Time Required to Achieve Clinically Significant Outcomes After Anteroinferior Arthroscopic Capsular Release for Shoulder Adhesive Capsulitis.

The specific time required to reach clinically significant outcomes for patient-reported outcome measures (PROMs) after arthroscopic capsular release (ACR) for the treatment of shoulder adhesive capsulitis remains unknown. To determine the time required to achieve the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) score thresholds after ACR for visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons score (ASES), Single Assessment Numeric Evaluation (SANE), and Constant score and to identify patient factors associated with delayed achievement of these clinical benchmarks. Case series; Level of evidence, 4. A prospective analysis was performed of patients who underwent ACR for the treatment of idiopathic shoulder adhesive capsulitis between October 2019 and October2020. Patients completed PROMs preoperatively and at 1, 2, 4, 6, and 12 months postoperatively. Threshold values for MCID and PASS were obtained from previous literature for the VAS, ASES, SANE, and Constant scores. A total of 73 patients were included (mean age, 55.5 ± 9.3 years; body mass index [BMI], 26.6 ± 4.6 kg/m2). By 1-year follow-up, the cumulative percentage of patients achieving the MCID and PASS for VAS, ASES, SANE, and Constant scores was 98.6%, 100%, 100%, and 98.6%, and 95.8%, 91.7%, 98.6%, and 84.9%, respectively. The median time required to reach the MCID thresholds for VAS, ASES, SANE, and Constant scores was 1, 1, 2, and 1 month, respectively. The median time required to reach the PASS thresholds for VAS, ASES, SANE, and Constant scores was 4, 4, 4, and 2 months, respectively. Factors associated with delayed achievement of MCID for SANE included higher BMI (hazard ratio [HR], 0.94; 95% CI, 0.88-0.99) and diabetes (HR, 0.49; 95% CI, 0.2-0.99). Age was associated with delayed achievement of the PASS for VAS. Most patients undergoing ACR achieved clinically significant outcomes within a 4-month timeframe. The majority of patients reached MCID thresholds on outcome measures within 1 to 2 months and achieved satisfactory symptom states within 2 to 4 months postoperatively. By delineating the timeline of patient-perceived benefits, these results provide useful data to set appropriate expectations, guide rehabilitation, and optimize outcomes after ACR.

Midterm Outcomes After Osteochondral Allograft Transplantation in the Knee Using High-Chondrocyte Viability Grafts.

Osteochondral allograft transplantation (OCAT) has become a standard-of-care treatment option for patients with large symptomatic articular defects. Recent advances in allograft science and OCAT protocols have been reported to result in consistently robust outcomes after OCAT in the knee. However, only short-term comparisons have been reported, and analyses are lacking for treatment failure risk factors that account for confounding variables. Midterm functional graft survival rate would exceed 80% for all OCATs combined, with consideration of risk factors for lower survivorship including older patient age, higher body mass index (BMI), tibiofemoral bipolar OCAT, and nonadherence to prescribed postoperative rehabilitation protocols. Case series; Level of evidence, 4. Patients with outcome data available at ≥5 years after primary OCAT using high chondrocyte-viability (HCV) osteochondral allografts were analyzed according to 2 clinically relevant definitions: (1) initial treatment failure, defined by revision or arthroplasty surgery performed for the primary OCAT at any time point during the study period; and (2) functional graft failure, defined by documented conversion to arthroplasty after primary or revision OCAT at any time point during the study period. Analyses were used to assess outcomes for each definition, separately for age group, sex, obesity status, tobacco use, type of OCAT surgery, osteotomy status, concurrent ligament surgery status, and adherence to postoperative protocols. Kaplan-Meier analyses were used to assess differences in survival rates, and Cox proportional hazards models were used to assess risk factors and multivariable relationships with survival. Patient-reported outcome measures for pain, function, mobility, and satisfaction were also analyzed. Analysis included 137 primary knee OCATs performed in 134 patients with a mean follow-up of 66 months (59 female, 75 male; mean age, 37.8 years; mean BMI, 28.5). The midterm (5- to 8-year) functional graft survival rate for patients undergoing primary OCAT in the knee using HCV grafts was 82% for all cases combined, ranging from 69% for tibiofemoral bipolar HCV OCATs to 89% for patellofemoral bipolar, 94% for multisurface unipolar, and 97% for single-surface unipolar. Initial treatment failure rates (revision or arthroplasty after primary OCAT) and OCAT nonsurvival rates (arthroplasty after primary or revision OCAT) were greater for older patient age, concurrent ligament reconstruction, tibiofemoral bipolar OCAT, and nonadherence to the prescribed postoperative rehabilitation protocols. When adjusted for patients' age, BMI, and tobacco use status, different surgery types did not demonstrate an increased risk for failure, while concurrent ligament reconstruction and nonadherence did. Patients who experienced functional graft survival after primary OCAT reported significantly greater improvements in PROMIS Physical Function and Mobility (Patient-Reported Outcomes Measurement Information System), International Knee Documentation Committee questionnaire, and Single Assessment Numeric Evaluation scores such that they were significantly higher at final follow-up as compared with patients who required arthroplasty. Patient-reported improvements in pain, function, and mobility exceeded minimal clinically important differences for ≥5 years after primary OCAT. When asked if they were satisfied with primary OCAT surgery, 76.2% of patients were very satisfied or satisfied with their results, while 8.5% were neutral and 15.4% were unsatisfied or very unsatisfied. With use of HCV osteochondral allografts, midterm (5- to 8-year) functional graft survival rates for patients undergoing primary OCAT in the knee were notably higher than previously reported midterm rates for traditional OCATs. When adjusted for patient characteristics, risk factors for nonsurvival included concurrent ligament reconstruction for knee instability and nonadherence to the prescribed postoperative rehabilitation protocols. Patients who experienced functional graft survival for ≥5 years after primary OCAT reported statistically significant and clinically meaningful improvements in pain, function, and mobility.

Comparison of clinical efficacy between reconstruction of the superior acromioclavicular ligament with acellular dermal allografts and clavicular hook plate in acromioclavicular dislocations

Purposes: We aimed to compare the clinical efficacy of superior acromioclavicular ligament reconstruction (SALR) using acellular dermal allograft with that of clavicular hook plate fixation (HP) in patients with acromioclavicular (AC) dislocations. We hypothesized that the SALR could provide more stability than hook plate. Methods: Twenty-two cases of acute AC joint dislocation between November 2021 to December 2023 were retrospectively reviewed. All patients were divided into 2 groups based on the treatment with SALR (12 cases) or HP (10 cases). Patients were evaluated radiologically and clinically using coracoclavicular distance and ratio, pain visual analogue scale (PVAS), Single Assessment Numerical Evaluation (SANE), and American Shoulder and Elbow Surgeons (ASES) at postoperative 3 months and 1 year. We evaluated whether patient achieve MCID of PVAS at the last visit, based on the minimal clinically important differences (MCIDs) of PVAS. Results: The SALR group showed a lower rate of reduction loss (8.3 % vs. 40.0 %) and similar clinical outcomes compared to the hook plate group. Initial SANE score was statistically significantly lower in SALR group (SANE: SALR, 45.8 ± 20.7; HP, 68.0 ± 15.5, p = 0.009), but there were no significant differences in final clinical outcomes, including PVAS, ASES, and SANE scores. Conclusion: SALR with acellular dermal allograft demonstrates comparable clinical outcomes to hook plate fixation and may offer a viable alternative, especially in complicated cases. Study Design: Case series; Level of evidence, 4.

Patients With Graft Tears Leaving the Tuberosity Covered Have Similar Functional Outcomes to Those With an Intact Graft After Superior Capsular Reconstruction.

Studies to date of superior capsular reconstruction (SCR) comparing outcomes of healed grafts versus torn grafts do not separate graft tears based on location of the tear, rather they combine and report all tears as a single group. The purpose of this study was to correlate functional outcome with graft integrity and graft tear location after SCR with a dermal allograft. It was hypothesized that the functional outcomes of patients with an intact graft would be equivalent to those with graft tears leaving the tuberosity covered. Cohort study; Level of evidence, 3. Patients who underwent SCR with an acellular dermal allograft at a single institution were included. Pre- and postoperative American Shoulder and Elbow Surgeons (ASES), Oxford Shoulder Score, visual analog scale (VAS) for pain, and postoperative Single Assessment Numeric Evaluation (SANE) scores were recorded. A magnetic resonance imaging scan was performed postoperatively to assess graft integrity. A total of 39 patients met inclusion criteria. Mean age of patients was 60.4 ± 8.7 years; mean follow-up was 53.3 ± 25 months (range, 14-98 months). Magnetic resonance imaging performed at a mean of 17.5 months (range, 6-66 months) demonstrated an intact graft in 14 (36%); tear from the glenoid in 11 (28%), from midsubstance in 4 (10%), and from the tuberosity in 8 (21%); and complete graft absence in 2 (5%). Patients were divided into group 1 (intact graft), group 2 (tuberosity covered: tears from glenoid and midsubstance tears), and group 3 (tuberosity bare: tears from the tuberosity and dissolved or absent grafts). In group 1, there was significant improvement in ASES (37.9 to 88.5; P < .001), Oxford (25.2 to 46.2; P < .001), and VAS (6.8 to 0.9; P < .001). In group 2, there was significant improvement in ASES (32.2 to 86.1; P < .001), Oxford (23.4 to 44.2; P < .001), and VAS (7.3 to 1.3; P < .001). In group 3, there was no significant improvement in ASES (40.3 to 45.8; P = .50) or Oxford (33.5 to 31.4; P = .81), but there was a significant reduction in VAS (7.1 to 5.4; P = .03). There was no significant difference between group 1 and 2 in postoperative ASES (88.5 vs 86.1; P = .59), Oxford (46.2 vs 44.2; P = .07), VAS (0.9 vs 1.3, P = .42) and SANE (85.4 vs 83.2; P = .92) scores. However, group 3 had significantly lower ASES (45.8; P < .001), lower Oxford (31.4; P < .001), lower SANE (45.4; P < .001), and higher VAS (5.4; P < .001) scores than groups 1 and 2. There were no differences in outcomes based on sex (P = .72), previous surgery (P = .06), preoperative acromiohumeral distance (P = .57), and preoperative Goutallier stage of the supraspinatus (P = .16). Patients who underwent SCR with a dermal allograft and developed a graft tear leaving the tuberosity covered had equivalent functional outcomes to those with an intact graft.

Increased Postoperative Deltoid Signal seen after Suprapectoral Biceps Tenodesis: Potential Risk to the Anterior Branch of the Axillary Nerve

BackgroundArthroscopic suprapectoral biceps tenodesis is a common procedure for lesions of the long head of the biceps in the setting of anterior shoulder pain. However, the distal portal poses a theoretical risk to the terminal branches of the axillary nerve as the nerve travels from posterior to anterior to innervate the anterior deltoid. The purpose of this retrospective cohort study was to assess for axillary nerve branch injury, identified by deltoid signal change in postoperative magnetic resonance imaging (MRI) in patients who underwent an arthroscopic suprapectoral biceps tenodesis. MethodsPatients who underwent rotator cuff repair with a concomitant arthroscopic suprapectoral biceps tenodesis, had a postoperative MRI, and at least 1 year of follow-up were included. The incidence of increased deltoid signal consistent with injury to an anterior branch of the axillary nerve on proton density fat saturated sequences was collected. Age, sex, body mass index (BMI), and patient reported outcome measures (PROMs) including the American Shoulder and Elbow Surgeons Shoulder Score (ASES) score, Patient-Reported Outcomes Measurement Information System (PROMIS) pain, physical function (PF), and upper extremity (UE) scores, and Single Assessment Numeric Evaluation (SANE) score were compared in patients with and without increased deltoid signal on postoperative MRI. P<0.05 was used for significance. ResultsTwenty-four patients were eligible for inclusion (9 female, average age 59.0±10.1, BMI 27.6±6.7). Edema-like signal within the anterior deltoid musculature was observed in 9 patients on postoperative MRI. Two patients had a second follow-up MRI performed which demonstrated resolution of signal, and one patient required a second surgery for release of adhesions. Patients with increased deltoid signal had higher BMI (p=0.03). There was no difference in any other demographic or postoperative PROM between patients with increased signal and those without at any follow-up time point. No patient demonstrated persistent weakness or numbness in the axillary nerve distribution at final follow-up. DiscussionOver one third of patients in our cohort had MRI evidence of axillary nerve branch injury as seen on proton density fat saturated MRI sequences postoperatively. The distal arthroscopic portal for a suprapectoral biceps tenodesis may place anterior terminal branches of the axillary nerve at risk for injury. Additional investigation and strategies for avoidance of nerve injury in this area should be pursued.

Autograft and Allograft ACLR in Patients Greater Than 40 Years Old Have Similar Short-Term Patient-Reported Outcomes with Higher Rates of ACL Graft Failure in Allograft Patients

PurposeThe purpose of this study was to evaluate short-term patient-reported outcomes (PROs) in patients aged 40 and older after primary ACLR between patients that received allograft or autograft. Secondary aims included assessing the effect of pre-existing osteoarthritis on short-term PROs. MethodsA retrospective review of an ambulatory surgery center’s electronic medical record was conducted for patients who underwent primary ACLR between 2009 and 2022. Patients aged younger than 40, those who underwent index revision procedures and/or concomitant ligament repair/reconstructions, and those with incomplete baseline or short-term (1- or 2-year) KOOS scores were excluded. Allograft and autograft patients were matched according to sex and body mass index (BMI) in a 2:1 fashion. PROs used included KOOS and Single Assessment Numeric Evaluation (SANE) at baseline and short-term follow up (minimum of 1 year). Minimum clinically important difference was calculated in a distribution-based fashion. Osteoarthritis severity was determined based on Kellgren-Lawrence grading of perioperative knee x-rays. Preexisting osteoarthritis was defined as KL grade 1 or more. ResultsA total of 331 patients were included after matching (215 allograft and 116 autograft patients). The average age was 47.7 ± 6.0 (range: 40-66). Age differed significantly between the two groups, with the allograft cohort having an average age of 48.6 ± 6.0 years and the autograft cohort having an average age of 46.1 ± 5.7 years (p < 0.001). Short-term change in KOOS and SANE scores did not differ by graft type (p = 0.154, p = 0.556, respectively). Sixty-seven percent of all patients met MCID for KOOS and 82% of patients with complete baseline and short-term SANE scores met MCID for SANE. There was a statistically significant difference in rupture rates between the allograft and autograft cohorts (n = 9 allograft vs n = 0 autograft; p = 0.030). There was no difference in re-operation rates between the autograft and allograft cohorts (p = 0.453). Perioperative Kellgren-Lawrence grading did not affect outcomes for either graft type (allograft: p = 0.905 vs. autograft: p = 0.522). ConclusionMiddle-aged patients undergoing ACLR with allograft or autograft demonstrate similar short-term patient reported outcomes. Pre-existing osteoarthritis similarly did not significantly affect short-term outcomes. However, rerupture rates were significantly higher in the allograft cohort than the autograft cohort.

Similar two‐year improvement in patient‐reported outcomes in patients 40 years and older with outerbridge grade III and IV lesions following ACL reconstruction

AbstractPurposeThis study aims to evaluate clinical and patient‐reported outcome measures (PROMs) of patients 40 years and older that underwent anterior cruciate ligament reconstruction (ACLR) and determine the influence of preexisting arthritis and chondral wear on ACLR outcomes. We hypothesized that patients aged 40+ with ACLR would have excellent clinical outcomes and PROMs regardless of preexisting arthritic changes.MethodsA total of 118 patients were included. Patients aged 40 years and older who underwent ACLR in a single healthcare system between 2009 and 2016 were eligible. Outcomes assessed include Knee Injury and Osteoarthritis Outcome Scores (KOOS), Single Assessment Numeric Evaluation (SANE) scores, intraoperative Outerbridge grading, preoperative Kellgren–Lawrence (KL) grading and postoperative complication rates over a 2‐year period.ResultsAverage increase in KOOS and SANE scores were 21.2 19.9 and 23.5 31.3, respectively. Patients with Outerbridge grade III and IV lesions in weight‐bearing compartments had lower baseline SANE and KOOS scores than those without (47.1 ± 22.0 vs. 64.5 ± 23.6 baseline SANE and 43.1 ± 18.1 vs. 63.5 ± 15.9 baseline KOOS; p = 0.002 and p &lt; 0.001, respectively) with no significant difference in the amount of change in SANE or KOOS scores (p = 0.111 and p = 0.165 respectively). Patients with KL‐grade 2+ osteoarthritis experienced similar changes in KOOS and SANE over the 2‐year period to their counterparts (p = 0.598 and p = 0.643, respectively).ConclusionThere is no correlation between preexisting osteoarthritic changes or chondral defects and PROs. KOOS and SANE scores both increased postoperatively. When treating older patients with an ACL tear, surgeons should consider the activity level and desires of the patient as they determine appropriate treatment. Preexisting osteoarthritis does not correlate with patient‐reported outcomes for ACLR.Level of EvidenceLevel IV

Considerations of throwing athletes with upper extremity injury when completing the Single Assessment Numeric Evaluation (SANE).

The Single Assessment Numeric Evaluation (SANE) is a widely used patient-reported outcome (PRO) measure that provides an efficient, but limited view of patient perceptions of health. Knowledge of what throwing athletes with upper extremity injury consider when answering the SANE would inform score interpretation and increase its value for clinical decision-making in this patient population. To investigate the global rating of the SANE and its ability to capture constructs of health reflected in patient-reported outcome measures that are commonly used in throwing athletes with upper extremity sport-related injury. Cross-sectional study. Retrospective database review. De-identified patient records of baseball and softball athletes diagnosed with upper extremity sport-related injury between October 2009 and June 2021 were reviewed. Primary outcomes were scores on the SANE; Functional Arm Scale for Throwers (FAST) total; Disabilities of the Arm, Shoulder and Hand (DASH) total; and Global Rating of Daily Activities (GRODA). The first administration of all PROs that patients completed post-injury were analyzed as potential predictors of SANE scores. The proportion of variance uniquely accounted for in the SANE by each predictor (R2) variable was estimated. Fifty-five patients completed PRO measures. The FAST total uniquely accounted for 32.9% (P <.001), the GRODA uniquely accounted for 11.6% (P <.001), and the DASH total uniquely accounted for 4.6% (P=.036) of the variance in the SANE score. Overall, the predictors accounted for 49.2% of the variance in the SANE score (P <.001). Given that the SANE captures multiple constructs of health, it may be useful in gathering a quick, broad view of throwing athletes' perception of their health. When SANE scores suggest diminished health, then multi-item PROs should be considered to further explore constructs of health most impacted.

Effects of Melatonin on Sleep Quality and Patient-Reported Outcomes After Arthroscopic Rotator Cuff Surgery: A Prospective Randomized Controlled Trial.

Sleep disturbance is a significant symptom associated with both rotator cuff tears and arthroscopic rotator cuff repair. Melatonin has been shown to be safe and effective in managing multiple sleep disorders, including secondary sleep disorders, with relatively minor adverse effects and lack of addictive potential. To investigate the effects of oral melatonin on postoperative sleep quality after arthroscopic rotator cuff repair. Randomized controlled trial; Level of evidence, 1. This was a prospective randomized clinical trial evaluating patients undergoing arthroscopic rotator cuff repair. Exclusion criteria included history of alcohol abuse, current antidepressant or sedative use, revision rotator cuff repair, severe glenohumeral arthritis, and concurrent adhesive capsulitis. Patients were randomly assigned in a 1:1 ratio to 1 of 2 groups: 5-mg dose of melatonin 1 hour before bedtime or standard sleep hygiene (≥6 hours per night, avoiding caffeine and naps in the evening). Patients in the melatonin group took their assigned melatonin dose for 6 weeks beginning the day of surgery. Patient-reported outcome assessments, including the Pittsburgh Sleep Quality Index (PSQI), the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and the Single Assessment Numeric Evaluation (SANE), and pain medication charts were collected preoperatively as well as at 2 weeks, 6 weeks, 3 months, 4 months, and 6 months postoperatively. Numeric variables were analyzed using paired and unpaired t tests, with significance set at P < .05. Eighty patients were included for final analysis (40 in the control group, 40 in the melatonin group). Patient characteristics such as age, sex, race, body mass index, and laterality did not differ significantly (P≥ .05). Preoperative ASES, SANE, and PSQI scores did not differ between groups (P≥ .055). PSQI scores were significantly lower (better quality sleep) in the melatonin group at the 6-week postoperative period (P = .036). There was a positive correlation between how patients rated the intensity of their pain and the PSQI at the 6-week postoperative period (0.566). The PSQI question regarding sleep quality was found to be significantly lower in the melatonin group at the 3-month, 4-month, and 6-month postoperative periods (P = .015, P = .041, and P≤ .05, respectively). SANE scores were significantly lower in the melatonin group (P = .011) at 6 weeks and then higher in the melatonin group (P = .017) at 6 months. ASES scores were significantly higher in the melatonin group at 4 and 6 months (P = .022 and P = .020, respectively). Lastly, patients who were randomized into the melatonin group were found to use significantly less narcotic medication at the 4-month postoperative period (P = .046). Melatonin use after arthroscopic rotator cuff repair led to improved sleep quality (PSQI) in the early postoperative period as well as improved functional outcomes (ASES and SANE scores) and decreased narcotic use in the later postoperative period. Patients with significant sleep disturbances associated with rotator cuff repairs may benefit from the use of melatonin. NCT04278677 (ClinicalTrials.gov identifier).

Predictors of Clinical Outcomes and Quality of Life After Sternoclavicular Joint Reconstruction With Hamstring Tendon Autograft

Background: Anterior instability of the sternoclavicular joint (SCJ) is a rare but potentially devastating pathological condition, particularly when it occurs in young or active patients. SCJ reconstruction using hamstring tendon autograft is a commonly used treatment option, yet to date results are limited to small case series. Studies on baseline, preoperative factors and their association with postoperative outcome are limited. Purpose: To assess the midterm clinical outcomes and survivorship after SCJ reconstruction using hamstring tendon autograft in patients experiencing anterior SCJ instability and to determine whether baseline patient or causative factors are associated with postoperative outcomes or patient satisfaction. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent SCJ reconstruction with a hamstring tendon autograft for anterior SCJ instability between October 2005 and October 2020 were included in this retrospective single-center study. At a minimum of 2 years postoperatively, clinical outcomes were collected, including the following patient-reported outcomes (PROs): the 12-Item Short Form Survey (SF-12) score; American Shoulder and Elbow Surgeons (ASES) score; Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score; Single Assessment Numeric Evaluation (SANE) score; and visual analog scale (VAS) pain score. Subjective postoperative satisfaction with the procedure was quantified on a scale from 0 (very unsatisfied) to 10 (very satisfied). The predictive role of patient factors, including age, sex, and injury in dominant arm, on postoperative PROs and satisfaction at short-term follow-up was evaluated using multiple linear regression. Results: A total of 49 patients (mean age, 29.6 ± 16.2 years; range 13.8-67.1 years; 27 females) were included in the final analysis. At a mean follow-up of 3.9 ± 2.1 years, all PROs had significantly improved, including the mean SF-12 Physical Component Summary score (40.4 ± 6.8 to 52.6 ± 6.9; P < .001), ASES score (54.9 ± 20.4 to 91.0 ± 11.3; P < .001), QuickDASH score (41.2 ± 18.5 to 10.2 ± 9.1; P < .001); SANE score (50.2 ± 21.1 to 88.3 ± 8.8; P < .001), VAS pain score (4.4 ± 2.6 to 0.8 ± 1.4; P < .001), and VAS pain score at its worst (7.4 ± 2.5 to 3.3 ± 2.6; P < .001). The median postoperative satisfaction score was 9 (range, 1-10). Revision-free survivorship was 95.9%. Male patients had a significantly lower VAS pain score at its worst compared with female patients (2.6 ± 2.6 vs 4.1 ± 2.4; P = .045); higher age was significantly correlated with a worse QuickDASH score (correlation coefficient, 0.314; P = .036). Overhead athletes had a significantly lower propensity to return to sport compared with nonoverhead athletes (P = .043), with only 45% of the overhead athletes returning to a level similar to their preinjury level, whereas 81% of the nonoverhead athletes were able to do so. Conclusion: The significant improvements in clinical and sport-specific outcomes and high patient satisfaction after SCJ reconstruction with a hamstring tendon autograft demonstrate the success of this procedure in treating anterior SCJ instability. Male sex and younger patient age are associated with superior outcomes, while overhead athletes have to be counseled about difficulties of returning to preinjury level of sport postoperatively.

Complications after primary and revision shoulder arthroplasty: a matched cohort study

BackgroundPatients who undergo total shoulder arthroplasty typically have excellent clinical outcomes, though some patients require revision shoulder arthroplasty to address complications such as infection, instability, and persistent pain. The purpose of this study was to compare the rates and types of complications, as well as patient-reported outcomes, following primary and revision shoulder arthroplasty. MethodsRetrospective chart review was conducted for patients who underwent revision anatomic or reverse shoulder arthroplasty between January 2015 and May 2021 (N = 152). A cohort of patients who underwent primary shoulder arthroplasty in the same period was generated by matching 1:1 for implant type (anatomic/reverse), age, and surgery date. Demographic data, patient-reported outcomes, surgical details, surgical complications, and reoperations were collected for both cohorts (N = 304). Chi-square, t-test, Fisher’s exact test, and Mann-Whitney test were used as appropriate. ResultsThe revision cohort had a significantly higher rate of surgical complications than the primary cohort (N = 58, 38.2% vs. N = 22, 14.5%; P < .0001). The distribution of complication types differed significantly between the primary and revision cohorts (P = .018). Revision patients reported less improvement in Single-Assessment Numeric Evaluation score from baseline to 2-year follow-up compared to primary patients (postoperative and preoperative scores 33.9 ± 35.9 vs. 52.3 ± 32.5; P = .036). Patients in the primary cohort who underwent a previous shoulder surgery before their shoulder arthroplasty were more likely to experience complications than those who did not (P < .001). The most common surgical complications in the revision cohort were persistent pain (N = 20) and periprosthetic joint infection (N = 10), while the most common complications in the primary cohort were persistent pain (N = 6) and instability (N = 4). 63.6% of complications in primary patients and 55.2% of complications in revision patients necessitated reoperation. Total procedure time was higher on average in revision patients (120 ± 68 min) than primary patients (94 ± 31 min; P < .0001). Revision patients were more likely than primary patients to have had cemented humeral stems in their primary arthroplasty (P = .043). ConclusionPatients undergoing revision shoulder arthroplasty are at an increased risk for subsequent surgical complications and worse clinical improvement compared to primary shoulder arthroplasty patients. The differing profiles of postoperative complication types following primary and revision shoulder arthroplasty should be considered when advising patients on the risks of surgery and creating preoperative surgical plans to minimize these risks.

Timing of Surgical Treatment for High-Grade Acromioclavicular Joint Injuries Does Not Affect Functional Outcomes

PurposeTo determine whether patient-reported outcomes are associated with surgical timing utilizing a multivariate regression. MethodsAC joint surgery patients from 2010-2019 were included if they underwent primary AC joint surgery for a Rockwood grade III-V AC joint separation. Chart review was conducted to determine time from injury to surgery, Rockwood injury grade, and surgical technique. Post-operative complications, revisions, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) scores, and radiographic outcomes were collected. Radiographic outcomes were determined by measuring coracoclavicular (CC) distance on preoperative, immediate postoperative, and all follow-up anterior-posterior views of the operative shoulder. Multivariate regressions were conducted with post-operative ASES, SANE, and CC distance as the outcomes of interest. ResultsOverall, 221 patients (104 early, 117 delayed) with an average age of 40±15 years were included in this study. Significant differences in patient age, BMI, injury grade, surgical technique utilized, and pre-operative CC distance were observed between groups (all p<0.05). After controlling for confounding variables such as age, sex, BMI, injury grade, and surgical technique, multivariate regression found that time from injury to surgery was not related to post-operative ASES score (R2=0.137, p=0.563) or post-operative SANE score (R2=0.087, p=0.441). Female patients had lower ASES scores than male patients (estimate: -8.25, 95% CI: -15.99 to -0.050, p=0.039), however no other significant relationships were identified from multivariate regression. ConclusionTiming of AC joint surgery did not affect functional outcomes. Clinicians may counsel patients that either early or delayed surgery may be appropriate.

Risk for Revision ACLR After Primary All-Inside Quadrupled Semitendinosus Hamstring Tendon Autograft ACLR With Independent Suture Tape Augmentation: A Retrospective Cohort Study.

The rate of failed anterior cruciate ligament reconstruction (ACLR) remains high in the younger and more active patient populations. Suture tape augmentation (STA) in addition to ACLR may reduce the risk for revision surgery. The purpose of this study was to compare patient outcomes between patients who underwent primary all-inside quadrupled semitendinosus hamstring tendon autograft (QST-HTA) ACLR with and without STA. It was hypothesized that the STA cohort would demonstrate a lower incidence of subsequent revision ACLR while maintaining comparable patient-reported outcomes. Cohort study; Level of evidence, 3. All patients ≤40 years of age who received primary all-inside QST-HTA ACLR with and without independent STA augmentation were identified. The following validated patient-reported outcome measures (PROMs) were collected: visual analog scale for pain, Single Assessment Numeric Evaluation, Knee injury and Osteoarthritis Outcome Score subscales, and Tegner activity scale. KT-1000 arthrometer measurements were collected pre- and postoperatively. Cox proportional hazards model and nominal logistic regression analysis were used to assess additional variables associated with revision ACLR. A total of 104 patients with a mean age of <22 years were included in the final data analysis (STA: 36 patients; control: 68 patients). Significantly fewer patients in the STA group sustained a graft failure necessitating revision surgery at the final follow-up (5.6% vs 24%; relative risk, 0.24 [95% CI, 0.06-0.97]; P = .017). Four-year graft survival was significantly higher in the STA group (97.2% vs 82.4%; P = .031). All PROMs significantly improved postoperatively except for Tegner levels, which decreased in both groups compared with their preinjury levels (P < .001). Return to sports was similar in both groups with >70% of patients returning to their previous level of competition. Regression analysis demonstrated increased risk for revision ACLR in younger patients, high school athletes, and those with higher postoperative activity levels. QST-HTA ACLR with STA was associated with reduced risk for revision ACLR compared with nonaugmented QST-HTA ACLR in this young patient population. Furthermore, the addition of suture tape did not appear to affect postoperative patient-reported and return-to-sports outcomes.

Analysis of Patients Who Undergo Index Arthroscopy With Biopsy but Not Implantation for Staged Chondrocyte Cell Transplantation.

Autologous chondrocyte implantation (ACI) and matrix-induced autologous chondrocyte implantation (MACI) are 2-stage procedures requiring an index full-thickness cartilage biopsy. Only a portion of patients ultimately undergo second-stage ACI/MACI. To identify patients with articular cartilage defects who underwent arthroscopic debridement with biopsy for ACI/MACI and compare those who did with those who did not proceed with implantation within 2 years after biopsy. Additionally, the authors sought to identify why patients did not proceed with implantation. Case-control study; Level of evidence, 3. Patients who underwent arthroscopy and autologous chondrocyte biopsy from January 1, 2015, to December 31, 2019, and who had minimum 2-year follow-up data were grouped into those who proceeded with second-stage ACI/MACI (implant group; n = 97) and those who did not (biopsy group; n = 63). Demographic factors, cartilage defect characteristics, and preoperative International Knee Documentation Committee (IKDC) scores were analyzed. Patients in both groups were evaluated postoperatively using the IKDC, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) for pain, and patients who did not undergo implantation were asked for their reasoning. Body mass index (BMI) (P < .001) and Outerbridge grades at index arthroscopy (P = .047) were significantly higher for the implant group than the biopsy group. Both groups had significantly improved IKDC scores from their initial presentation to final follow-up (implant group: 46.4 ± 16.2 preoperative vs 69.6 ± 20.6 postoperative [P < .001]; biopsy group: 47.2 ± 15.9 preoperative vs 70.7 ± 19.1 postoperative [P < .001]); however, the level of improvement did not differ significantly between groups. Postoperative WOMAC, SANE, and VAS pain scores were also similar between groups. In the biopsy group, 23 patients (37%) cited symptom resolution or activity level improvement after initial arthroscopy as the reason for not proceeding with implantation. Patients who proceeded to the second stage of chondrocyte implantation via either ACI or MACI had higher-grade articular defects and higher BMI compared with those who underwent biopsy with concomitant debridement chondroplasty alone. Postoperative outcomes were similar between the groups.

Comparison of clinical outcomes of anterior combined latissimus dorsi and teres major tendon transfer for anterior superior irreparable rotator cuff tear between young and elderly patients.

Anterior combined latissimus dorsi and teres major (aLDTM) tendon transfer has shown promise as a treatment for anterior superior irreparable rotator cuff tears (ASIRCTs). Our study aimed to compare aLDTM clinical outcomes for ASIRCTs between young and elderly patients. This retrospective study reviewed data from patients who underwent aLDTM tendon transfer for ASIRCTs with minimum 2-year follow-up. Clinical evaluations included visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), active range of motion (aROM), strength, and complications. Radiologic assessments included acromiohumeral distance, Hamada classification, and integrity of transferred tendon. Patients were divided into group total (all ages), group old (≥70 years), and group young (≤60 years). A total of 123 patients were enrolled with 39 in group young (mean age, 56.6±4.9 years) and 27 in group old (mean age, 73.6±2.3 years). Postoperatively, both groups showed significant improvements in VAS, ASES, and SANE scores and improved aROM for forward elevation, abduction, and internal rotation. No significant differences in clinical coutcomes were noted between the groups. Furthermore, similar rates of complications, including retears and postoperative infections, were observed across all three groups. Our study highlights the effectiveness of aLDTM transfer for ASIRCTs with minimal glenohumeral arthritis, demonstrating similar outcomes in both group young and group old patients. Moreover, patients in these distinct age groups showed comparable clinical results when compared to group total. Level of evidence: III.

Fresh Osteochondral Allograft Transplantation of the Capitellum for the Treatment of Osteochondritis Dissecans

Background: Osteochondritis dissecans (OCD) of the humeral capitellum is a rare and challenging condition to treat. Several surgical options exist, but in the last few years, the pendulum has swung from debridement and microfracture to restoration of the articular surface. Osteochondral autografts from the rib and knee have been described, but donor-site morbidity is a concern. Purpose: To expand the results of fresh osteochondral allograft transplantation (FOCAT) in a previously published report with inclusion of additional patients and a longer follow-up period. Study Design: Case series; Level of evidence, 4. Methods: After institutional review board approval, the charts of patients who underwent FOCAT for OCD of the capitellum between 2006 and 2022 by a single surgeon were reviewed. The majority of cases (94%) had unstable lesions (Minami grades 2 and 3). A trial of nonoperative treatment had failed in all. All patients underwent diagnostic arthroscopy, followed by a mini-open, ligament-sparing approach with grafting using commercially available guides and instruments. Results: A total of 35 patients were identified, of whom 25 were male. The mean age was 16 ± 3.9 years (range, 11-32 years). There were 24 baseball players (19 pitchers and 5 position players), 5 gymnasts, 3 cheerleaders/tumblers, 1 tennis player, 1 student (who did not participate in athletics), and 1 patient with avascular necrosis from chemotherapy. Eighteen patients had a mean flexion contracture of 14.1°± 11.9°. A single osteochondral allograft plug was used in 23 patients (mean diameter, 11.3 ± 2.8 mm), and 12 patients required 2 plugs (Mastercard technique). The mean follow-up was 92.6 ± 54.5 months (range, 24-204 months). There was significant improvement in Oxford (from 25.5 ± 4.9 to 46.7 ± 3.5; P < .00001) and visual analog scale for pain (from 7.5 ± 2 to 0.3 ± 1.0; P < .0001) scores. The mean Single Assessment Numeric Evaluation score at the time of follow-up was 90.6 ± 10.8 (range, 60-100). In overhead athletes, there was significant improvement in the Kerlan-Jobe Orthopaedic Clinic score (from 40.8 ± 11.8 to 90.6 ± 10.8; P < .00001). A postoperative magnetic resonance imaging scan was obtained in 16 (46%) patients at a mean of 32.6 months. In all cases, the graft was incorporated. All overhead athletes were able to return to their sport and perform at the same level or higher for >2 years. Two elbows required a subsequent arthroscopy for loose-body removal; otherwise, there were no other complications. Conclusion: FOCAT is an excellent option for treating OCD lesions of the humeral capitellum. Excellent outcomes and high return-to-sport rates were observed, with midterm follow-up showing no graft failures. FOCAT eliminates donor-site morbidity.

Sensory neurapraxia after distal biceps repair is not associated with patient-reported outcomes or satisfaction: a retrospective cohort study

Cutaneous neurapraxia is the most common complication following distal biceps tendon repair (DBTR). Currently, no patient demographic factors have been implicated in its occurrence, course, or resolution. The purpose of this study is to explore various patient demographics and their association with postoperative neurapraxia. Further it investigates how mental health scores correlate with patient-reported outcomes, and whether occurrence of neurapraxia alters this association. This retrospective review evaluates a consecutive series of patients who underwent distal biceps repair with a single-incision cortical button technique. Patients with reported outcome data at a minimum of 1year (n=47) were included for analysis. Demographic data including age, sex, body mass index, diabetes, smoking status, and occurrence of neurapraxia were recorded. Patient-reported outcome measures include the American Shoulder and Elbow Surgeons-Elbow score, Single Assessment Numeric Evaluation score, Visual Analog Scale for pain, Disabilities of the Arm, Shoulder, and Hand Score, and Veterans RAND 12 (VR-12) Mental Component Score and Physical Component Score quality-of-life assessment. Postoperative neurapraxia of any duration occurred in 45% (21/47) of patients in this cohort following DBTR. Of these, 62% (13/21) reported resolution of symptoms by the latest follow-up. Mean time to resolution of neurapraxia was 148days. Patient age, body mass index, smoking history, time to surgery, tear thickness, and increasing surgeon experience across the study period were not significantly associated with the incidence or time to resolution of postoperative neurapraxia. Scores for patient satisfaction, Visual Analog Scale, American Shoulder and Elbow Surgeons, Disabilities of the Arm, Shoulder, and Hand Score, Single Assessment Numeric Evaluation, VR-12 Mental Component Score, VR-12 Physical Component Score, and flexion ROM did not differ significantly between patients with and without postoperative neurapraxia. Patient satisfaction following DBTR was not significantly associated with postoperative neurapraxia. Patient and surgical characteristics did not influence the occurrence or time to resolution of neurapraxia. The occurrence of postoperative neurapraxia did not result in significant functional limitations.

Rate of graft retear is higher in over-the-top superior capsular reconstruction for massive posterosuperior rotator cuff tears with subscapularis tear.

To compare side-to-side superior capsular reconstruction (SCR) with over-the-top SCR in terms of functional outcomes, pain relief and allograft survival rates. Patients who had undergone arthroscopic dermal allograft SCR for massive irreparable rotator cuff tears and clinical follow-up for ≥2 years were recruited. All patients underwent postoperative assessment with routine radiographic analysis for acromiohumeral distances, ultrasound imaging 1 and 3 months after SCR and magnetic resonance imaging (MRI) at least 12 months after SCR. The outcome measures were visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), Constant and Single Assessment Numeric Evaluation (SANE) scores. SCR was performed in 56 patients including side-to-side SCR in 32 and over-the-top SCR in 24. Postoperative MRI showed that the grafts were intact in 46 patients (82.1%; 26 who underwent side-to-side SCR and 20 who underwent over-the-top SCR). The proportion of nonhealing grafts in the over-the-top group was significantly higher with concomitant subscapularis tears (60% vs. 5.3%; p = 0.02). VAS scores and functional outcomes improved postoperatively in both groups and postoperative VAS (1.4 vs. 1.7; n.s.), Constant (74.8 vs. 76.0; n.s.), mean ASES (87.4 vs. 89.1; n.s.) and mean SANE (81.7 vs. 84.3; n.s.) scores did not differ significantly. For massive rotator cuff tears, over-the-top and side-to-side SCR achieve similar pain relief and functional improvement, and the rate of healing allografts is high. However, over-the-top SCR is not recommended for massive posterosuperior rotator cuff tears with repairable subscapularis tendon tears due to a higher nonhealing rate. Level III.

Single Assessment Numeric Evaluation score in shoulder pathologies: cross-cultural adaptation and validation into Russian

Background. Single Assessment Numeric Evaluation (SANE) Score is a single-answer scale widely used within the global medical community. However, to date, it has not been adapted and validated into Russian, particularly as a tool to assess orthopedic shoulder conditions. The aim of the study is to conduct a cross-cultural adaptation and validation of the Russian version of the SANE score as an assessment tool of orthopedic shoulder conditions. Methods. The study included a total of 160 patients with various shoulder pathologies, of which 101 (63%) males and 59 (37%) females. The median age was 45 (37-52) years. At the first stage of the study, we performed cross-cultural adaptation of the SANE score into Russian. The second stage was the validation of the obtained score. Its reliability, validity and responsiveness were evaluated. Reliability was assessed by “test-retest” method. It allowed to measure an intra-class correlation coefficient (ICC) between the SANE score results obtained at the time of the first appointment and again in 14 days. The validity assessment was based on the comparison of the SANE and ASES (have already been adapted into Russian) score results. Responsiveness was assessed using statistical analysis for two dependent samples and calculation of the Guyatt’s Responsivity Index (GRI). Floor and ceiling effects were evaluated as the percentage of patients who reported either minimum or maximum scores. Results. The psychometric properties assessment has revealed good indicators of reliability (ICC = 0.77), validity (a strong direct correlation between SANE and ASES scores = 0.707; a moderate strength inverse correlation with ASES “Intensity of pain” subsection = 0.542) and responsiveness (GRI = 1.861). Floor and ceiling effects accounted for 1% and 3%, respectively, (all below 15%). Conclusions. Adapted to assess the shoulder conditions, the Russian version of the SANE score has good psychometric properties. Its advantage is the combination of completion speed and ease of use with a high-quality integrated subjective assessment of the patients’ set of complaints.

Poster 147: Patient-Reported and Clinical Outcomes up to 2 Years after Primary Rotator Cuff Repair: Do We Need a 2-Year Follow-Up Visit?

Objectives: Rotator cuff tears (RCTs) are the number one cause of shoulder pain and are becoming increasingly common as the population ages. The increasing incidence of RCTs present a significant economic burden, with shoulder pain being the No. 1 cause of disability in the United States. Repair of RCTs, in return, result in a cumulative $3.4 billion savings annually in the United States. Historically, follow-up for rotator cuff repair (RCR) mirrors that of hip and knee arthroplasty, with minimum of 2-year outcomes reported in most peer-reviewed studies. Recent literature, however, demonstrates no significant increase in clinically significant improvement after 6 months regarding functional outcomes and patient-reported outcomes (PROs) such as American Shoulder and Elbow Surgeons Shoulder Score (ASES), visual analog scale (VAS), and Disabilities of the Arm, Shoulder, and Hand (DASH) scores among others. The purpose of this study is to demonstrate degradation of outcome improvement in patient-reported outcomes after 1-year follow-up of RCR. We hypothesize that there will be no clinically significant increase in Single Assessment Numeric Evaluation (SANE) scores after 1 year postoperatively. The primary outcome of interest is change in SANE score over the 2-year episode of care. Methods: All patients that underwent primary RCR within a single health care system were eligible for inclusion in this study. Exclusion criteria included history of surgery on the affected shoulder, incomplete PROs at baseline, 1 year, or 2 years postoperatively, and concomitant fractures about the affected shoulder. Patient demographics, injury characteristics, and operative technical characteristics were obtained through review of the patients’ electronic medical records and operative reports. PROs included SANE, ASES, and VAS scores and were collected prospectively, then stored in a HIPAA-compliant database until reviewed retrospectively for this study. An anchor-based minimum clinically important difference (MCID) was calculated for the study cohort at 1 and 2 years postoperatively and was anchored on a 1-point increase in the Patient-Reported Outcomes Measurement Information System global 10 quality of life question. The primary outcomes of interest are baseline (preoperative), 1-year, and 2-year SANE scores. Secondary outcomes of interest included rates of symptomatic retear, reoperation, and revision. Statistical analysis was performed with a statistical analysis software (Intellectus). Analyses included descriptive statistics, t tests, chi-square tests of independence, Fischer exact tests, and analyses of variance, as appropriate. Statistical significance was defined as an alpha value of p ≤ 0.05. Results: A total of 495 patients met criteria for inclusion in the study (Table 1). The average age of the study population was 61.5 ± 8.4 years old, and the average body mass index (BMI) was 29.9 ±5.5. Most patients were men (287, 58.0%). A total of 24 patients were under workers’ compensation. Other medical comorbidities of interest included diabetes (74, 15.0%), depression (85, 17.2%), anxiety (74, 15.0%), and rheumatoid arthritis (6, 1.2%). Just over half of patients had chronic tears as described by the surgeon in clinical notes or operative reports (259, 52.3%), and most patients had full-thickness tears documented in the operative report (402, 81.2%). The most common adjuvant procedures included subacromial decompression (SAD) (419, 84.6%), biceps tenodesis (211, 42.6%) and distal clavicle excision (DCE) (133, 26.9%). Baseline SANE scores for the study cohort averaged 40.8 ± 20.3 with a subsequent of 43.4 within the first year postoperatively, bringing the 1-year SANE average to 84.1 ± 196 (p &lt; 0.001). After the 1-year follow-up, however, there was small but statistically significant change in SANE scores with the 2-year SANE scores averaging 87.5 ± 18.1, p &lt; 0.001) (Figure 1). One-year anchor-based MCID for SANE was found to be 45.5, with 238 (48.1%) meeting this MCID. At 2-years, 213 patients (43.0%) met the MCID of 50.6. Conclusions: Over the 2-year episode of care following primary RCR, patients saw an overall increase in SANE of 46.8. Even after the 1-year follow-up, patients continued to see statistically significant increases in SANE scores; however, they did not see clinically significant increase in PROs, as demonstrated by fewer patients meeting the 2-year MCID compared with the 1-year MCID.
