Unicortical versus bicortical plate fixation for midshaft clavicular fractures

BackgroundThe aim of this study was to compare the functional and radiological outcomes of unicortical vs bicortical fixation in patients with midshaft clavicular fractures who were treated using pre-contoured locking plates. MethodsWe performed a prospective multicenter study of 45 individuals who underwent open reduction and internal fixation of midshaft clavicular fractures with precontoured locking plates between March 2017 and December 2019. Twenty-five patients were treated with bicortical screws and 20 patients with unicortical screws. Functional outcomes were assessed at 6 months and 12 months after surgery using the Constant score, the 11-item version of the Disabilities of Arm, Shoulder and Hand (Quick- DASH) score and the Single Assessment Numeric Evaluation (SANE) score. Pain was evaluated using a visual analog scale (VAS). The rate of return to work and sports was also recorded. Radiologic evaluation was obtained in the immediate postoperative day, monthly until fracture consolidation, at 6 months and 12 months. All intraoperative and postoperative complications were documented. ResultsAt both 6 and 12 months, the follow-up rates were 100%, and the mean age was 28.5 years (range, 20 to 45 years). The mean postoperative Constant score, Quick DASH, and SANE score at 12 months were 93.5 (±6), 2.3 (±3), and 92% (±7), respectively. There were no significant differences in the functional scores between the groups neither at 6 months nor at 12 months. Of the 30 active workers, 97% were able to return to their previous working routine and from the 25 patients who practiced sports before the injury,92% returned to sports all at the same level. All the fractures healed in both groups. There were 6 complications (13%). ConclusionIn young, active patients with displaced midshaft clavicular fractures, both unicortical and bicortical locked plates achieved 100% bone consolidation, with excellent functional outcomes and a low rate of complications without significant differences between the groups. Therefore, locked plates with unicortical fixation could be a very good alternative for the management of young patients with midshaft clavicular fractures, potentially avoiding severe neurovascular complications.

Augmentation of ACL Autograft Reconstruction With an Amnion Collagen Matrix Wrap and Bone Marrow Aspirate Concentrate: A Pilot Randomized Controlled Trial With 2-Year Follow-up.

It is theorized that the lack of a synovial lining after anterior cruciate ligament (ACL) injury and ACL reconstruction (ACLR) contributes to slow ligamentization and possible graft failure. Whether graft maturation and incorporation can be improved with the use of a scaffold requires investigation. To evaluate the safety and efficacy of wrapping an ACL autograft with an amnion collagen matrix and injecting bone marrow aspirate concentrate (BMAC), quantify the cellular content of the BMAC samples, and assess 2-year postoperative patient-reported outcomes. Randomized controlled trial; Level of evidence, 2. A total of 40 patients aged 18 to 35 years who were scheduled to undergo ACLR were enrolled in a prospective single-blinded randomized controlled trial with 2 arms based on graft type: bone-patellar tendon-bone (BTB; n = 20) or hamstring (HS; n = 20). Participants in each arm were randomized into a control group who underwent standard ACLR or an intervention group who had their grafts wrapped with an amnion collagen matrix during graft preparation, after which BMAC was injected under the wrap layers after implantation. Postoperative magnetic resonance imaging (MRI) mapping/processing yielded mean T2* relaxation time and graft volume values at 3, 6, 9, and 12 months. Participants completed the Single Assessment Numeric Evaluation Score, Knee injury and Osteoarthritis Outcome Score, and pain visual analog scale. Statistical linear mixed-effects models were used to quantify the effects over time and the differences between the control and intervention groups. Adverse events were also recorded. No significant differences were found at any time point between the intervention and control groups for BTB T2* (95% CI, -1.89 to 0.63; P = .31), BTB graft volume (95% CI, -606 to 876.1; P = .71), HS T2* (95% CI, -2.17 to 0.39; P = .162), or HS graft volume (95% CI, -11,141.1 to 351.5; P = .28). No significant differences were observed between the intervention and control groups of either graft type on any patient-reported outcome measure. No adverse events were reported after a 2-year follow-up. In this pilot study, wrapping a graft with an amnion collagen matrix and injecting BMAC appeared safe. MRI T2* values and graft volume of the augmented ACL graft were not significantly different from that of controls, suggesting that the intervention did not result in improved graft maturation.

Sternoclavicular joint reconstruction for traumatic acute and chronic anterior and posterior instability: Patient-reported outcomes at a minimum of 2 years.

Instability of the sternoclavicular joint (SCJ) is a rare problem that is often treated closed, with few published outcomes of surgical treatment with tendon graft reconstruction. We reviewed a consecutive series of patients who underwent tendon graft reconstruction for SCJ instability over a 7-year period. Cases with acute fractures or fewer than 2 years of follow-up were excluded. Pre- and postoperative function and pain were assessed using Single assessment numeric evaluation (SANE), simple shoulder test (SST), and visual analog scale (VAS) outcome measures. Thirty cases were included, with 27 (90%) available for follow-up at a minimum of 2 years postoperatively. SANE scores improved from a median of 40 to 90. SST scores improved from a median of 3 positive responses to a median of 12 on a 12-point scale. VAS scores decreased from a median of 7 to 0 points. One patient underwent reoperation for recurrent instability and wound dehiscence. Three (11%) patients did not achieve a minimum 30% of maximum possible improvement in SST scores. Tendon graft reconstruction for SCJ instability is a safe procedure with a low complication rate and statistically and clinically significant improvements in patient-reported outcome measures at 2-year minimum follow-up. Level IV: Therapeutic.

Clinical outcomes of revision to anatomic total shoulder arthroplasty

BackgroundAnatomic total shoulder arthroplasty (aTSA) remains the gold-standard for management of end-stage glenohumeral arthritis. However, in the setting of failed hemiarthroplasty or aTSA, the appropriate utilization of revision to an anatomic vs. reverse TSA remains unknown. This study aims to assess the outcomes of revision to aTSA. MethodsAll revision shoulder arthroplasty cases at a single institution by one of five fellowship-trained surgeons were reviewed. All aseptic revision cases where the revision construct was an aTSA were included. Attempts were made to contact each case for enrollment in the institution’s shoulder registry and ascertain any cases requiring revision surgery. Patient-reported outcome measures: American Shoulder and Elbow Surgeons score, single assessment numeric evaluation, visual analog scale for pain, patient satisfaction, and a validated scale of patient-reported shoulder range-of-motion were collected. ResultsTwenty eight cases underwent revision aTSA between 2004 and 2019. The average age was 53.4 years (range: 23-66), 16 (57%) were male, and 14 (50%) were revised from a hemiarthroplasty while the remainder were revised from an aTSA. Seven (25%) cases required revision surgery at a mean 1.8 years. Three of these cases had been revised from hemiarthroplasty. Reasons for revision included: glenoid loosening (1), infection (1), rotator cuff failure (3), and persistent pain of nonspecific etiology (2). Ultimately, 6 (21%; 6/28) were revised to reverse TSA at a mean of 2 years (range: 1 month-5.7 years) postoperatively. Patients requiring further revision surgery were older (58.8 vs. 51.4 years; P = .06) than those not requiring further revision. Of the patients managed with lesser tuberosity osteotomy, the revision rate was 7.1% (1/14) compared to 42.9% (6/14) for the remainder of the cohort (P = .08). Of the 21 patients with retained aTSA, 15 (71%) provided clinical follow-up at an average of 4 years (range: 1-8). These patients had a mean American Shoulder and Elbow Surgeons score of 70.2 (range: 41-94), visual analog scale pain score of 2.8 (range: 0-6), single assessment numeric evaluation score of 52.1% (range: 14-92), and satisfaction of 73% (range: 1-100). DiscussionThe outcomes of revision shoulder arthroplasty to an aTSA construct are varied. While in the appropriately indicated young patient high-quality results can be achieved, there is a high revision rate and highly variable patient-reported outcomes. Surgeons should be selective when recommending revision to an aTSA. Further study is needed to better predict successful outcomes in this patient population.

Prevalence, Timing, Locational Distribution, and Risk Factors for Heterotopic Ossification After Elbow Arthroscopy

Background: Arthroscopic techniques aim to reduce complications and accelerate recovery of the elbow after treatments for posttraumatic stiffness, arthritis diseases, lateral epicondylitis, ligament reconstruction, and elbow trauma. However, data on the true prevalence and characteristics of heterotopic ossification (HO) formation after elbow arthroscopy are limited. Purpose: To investigate the prevalence, timing, locational distribution, and risk factors of HO after elbow arthroscopy. Study Design: Cohort study; Level of evidence, 4. Methods: Data on 205 patients undergoing elbow arthroscopy by a single senior elbow surgeon at a single institution between May 2011 and January 2022 were retrospectively reviewed. The patients were evaluated at 2 weeks, 8 weeks, 6 months, and then annually after surgery or more frequently if HO developed, with a minimum of 1 year of postoperative follow-up. Postoperative anteroposterior and lateral elbow radiographs were taken at 2 weeks to rule out fracture and at 8 weeks to identify HO. The clinical outcomes were evaluated based on the pain visual analog scale; the shortened version of the Disabilities of the Arm, Shoulder and Hand score; Mayo Elbow Performance Score; and the Single Assessment Numeric Evaluation scores before and after surgery. Bivariate logistic regression analyses were used to determine factors affecting HO prevalence. Results: Thirteen (12 male, 1 female) of 205 (6.3%) patients developed HO, with 10 (76.9%) with HO that formed on the medial compartment of the elbow. Ten (76.9%) patients were diagnosed at 8 weeks after arthroscopic surgery, 1 (7.7%) at 6 months after surgery, and 2 (15.4%) at 12 months after surgery. HO was not found at 2 weeks after surgery in any patient. The mean follow-up time was 3.5 years (range, 1.0-11.8 years). Eleven asymptomatic patients were treated nonoperatively, and 2 symptomatic patients underwent HO excision arthroscopically or had a combination of open surgery and arthroscopy. Age was a protective factor for HO formation (odds ratio [OR], 0.953; 95% CI, 0.910-0.999; P = .047). The risk factors for HO formation were tourniquet time (OR, 1.042; 95% CI, 1.019-1.065; P < .001) and surgical time (OR, 1.026; 95% CI, 1.011-1.041; P < .001). Conclusion: Among 205 patients who underwent elbow arthroscopy, HO was a minor complication of elbow arthroscopy, with a prevalence rate of 6.3%, and was usually located on the medial compartment of the elbow. Although the presence of HO may not affect the clinical outcomes in most patients, it should be carefully monitored for a minimum of 8 weeks postoperatively. Younger age, longer tourniquet time, and longer surgical time contributed to HO formation after elbow arthroscopy.

Reverse Shoulder Arthroplasty Patients Younger Than 60 Years Old Exhibit Lower Clinically Significant Single Assessment Numeric Evaluation (SANE) Scores Compared to Older Patients.

The incidence of reverse shoulder arthroplasty (RTSA) in the United States has increased. Patients under 60 years old with failed rotator cuff repairs or degenerative joint disease with glenoid deformity may be candidates for RTSA and contribute to this increase. The single assessment numeric evaluation (SANE) score is a reliable post-operative scoring technique when compared with other post-operative measures. This study aimed to compare the effect of age on the likelihood of reaching clinically significant SANE scores following RTSA. A multicenter retrospective review was performed with a consecutive series of RTSA from December 2015 to September 2021. Patients were stratified into groups based on their age at the time of operation: (1) less than 60 years old, (2) 60-69 years old, (3) 70-79 years old, and (3) greater than 80 years old. The proportions of patients in all cohorts reaching and surpassing clinically significant thresholds at each visit were determined.Likelihood ratios were determined for each age cohort to compare the likelihood of reaching clinically significant SANE scores. A total of 292 of 885 (33%) patients had completed survey data over two years and were included in the study. The 70-79-year-old group was 3.152 (p=.035) times more likely to achieve minimal clinically important difference (MCID) and 2.125 (p=.048) times more likely to achieve patient-acceptable symptomatic state (PASS) compared with patients <60 years old. The cohort who was 80+ years old was also 4.867 (p=.045) times more likely to achieve MCID compared to the <60-year-old cohort. The <60 cohort had the lowest proportion of all patient cohorts achieving MCID. A lower proportion of patients younger than 60 years old undergoing RTSA achieved clinically significant post-operative SANE scores. The 70-79-year-old age group was more likely to reach MCID and PASS, and the patients who were 80+ years old were more likely to reach MCID compared to patients younger than 60 years old.

Increased patient resilience scores are related to positive postoperative outcomes in rotator cuff repairs

We sought to determine whether patients' preoperative resilience scores predict postoperative outcomes in arthroscopic rotator cuff repair surgery. Patients were prospectively enrolled and underwent data collection preoperatively and at 3, 6, 12, and 24 months postoperatively. Data collected included demographic characteristics and the Brief Resilience Scale (BRS) score, visual analog scale score, Veterans RAND 12-Item Health Survey scores (mental component [VR-12M] and physical component [VR-12P]), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score, Single Assessment Numeric Evaluation score, and Simple Shoulder Test (SST) score. In total, 131 patients had complete 1- or 2-year postoperative outcome measures. Female patients comprised 56.5% of our sample, and the average age was 57.6 years. Between the low, normal, and high resilience groups, there were significant differences in the VR-12M scores at 0, 12, and 24 months postoperatively (P<.01 for all). The VR-12P scores at 12 months were 44.2, 47.4, and 49.8 in the low, normal, and high resilience groups, respectively, showing a trend upward, but this failed to reach the level of significance (P=.08). The SST scores of the low, normal, and high resilience groups at 12 months were 69.1, 79.9, and 85.1, respectively, again showing a trend upward, but this failed to reach the level of significance (P=.07). The SST scores at 0 and 24 months did not differ between groups. There were no significant differences in American Shoulder and Elbow Surgeons, visual analog scale, and Single Assessment Numeric Evaluation scores at 0, 12, or 24 months postoperatively. We found a significant positive correlation between the BRS score and SST score at 12 months (R=0.18), VR-12M score at 12 months (R=0.38), VR-12M score at 24 months (R=0.31), and VR-12P score at 12 months (R=0.21). Our study provides evidence that BRS scores in patients undergoing arthroscopic rotator cuff repair are related to postoperative outcomes, measured through the VR-12M and SST scores at 2-year follow-up.

Mid-term outcomes of arthroscopically assisted lower trapezius tendon transfer using Achilles allograft in treatment of posterior-superior irreparable rotator cuff tear

Arthroscopically assisted lower trapezius tendon (aLTT) transfer is one of the treatment options for posterior-superior irreparable rotator cuff tears (PSIRCTs). Although short-term clinical outcomes have shown promising results, there are currently no reported clinical outcomes over a longer follow-up period. This study evaluated the mid-term outcomes of aLTT transfer in patients with a diagnosis of PSIRCT. This retrospective case-series study included patients who underwent aLTT transfer between May 2017 and May 2019. The clinical outcome assessment included the visual analog scale (VAS) pain score, Constant score, American Shoulder and Elbow Surgeons score, University of California-Los Angeles score, Activities of Daily Living Requiring Active External Rotation (ADLER) score, active range of motion, Single Assessment Numeric Evaluation score, and return-to-work rate. The radiographic analysis included the acromiohumeral distance, Hamada grade, and integrity of the transferred tendon at final follow-up. Subgroup analyses were performed based on the integrity of the transferred tendon and the trophicity of the teres minor (Tm). This study enrolled 36 patients with a mean age of 63.4 years who met the inclusion criteria and were followed up for a mean of 58.2±5.3 months. At final follow-up, the patients showed significant improvement in mean VAS score, Constant score, American Shoulder and Elbow Surgeons score, University of California-Los Angeles score, ADLER score, and active range of motion in all directions except internal rotation. A decrease in the acromiohumeral distance and an increase in the Hamada grade were observed at final follow-up (P=.040 and P=.006, respectively). Retears of the transferred tendon occurred in 7 patients, and postoperative infections developed in 2 individuals. An interesting finding was that the retear group still demonstrated improvement in the VAS score but did not show improvement in external rotation at the side by the final follow-up. Compared with the Tm non-hypertrophy group, the Tm hypertrophy group showed significantly better improvement in external rotation at 90° of abduction and at the side, as well as the ADLER score. Of the study patients, 30 (83.3%) were able to successfully resume their previous work. In this study, aLTT transfer in patients with PSIRCTs demonstrated significant improvements in clinical and radiologic outcomes by the final follow-up. These findings provide support for the mid-term safety and effectiveness of aLTT transfer as a viable joint-preserving treatment option for PSIRCTs. However, larger and longer-term studies are still needed to further validate these findings.

Simultaneous Arthroscopic Rotator Cuff Repair and Glenoid Microfracture in Active-Duty Military Patients Younger Than 50 Years: Outcomes at Midterm Follow-up.

While concomitant full-thickness rotator cuff tears and glenoid osteochondral defects are relatively uncommon in younger patients, military patients represent a unique opportunity to study this challenging injury pattern. To compare the outcomes of young, active-duty military patients who underwent isolated arthroscopic rotator cuff repair (ARCR) with those who underwent ARCR plus concurrent glenoid microfracture (ARCR+Mfx). It was hypothesized that ARCR+Mfx would produce significant improvements in patient-reported outcome measures. Cohort study; Level of evidence, 3. This was a retrospective analysis of consecutive active-duty military patients from a single base who underwent ARCR for full-thickness rotator cuff tears between January 2012 and December 2020. All patients were <50 years and had minimum 2-year follow-up data. Patients who underwent ARCR+Mfx were compared with those who underwent isolated ARCR based on the visual analog scale (VAS) for pain, Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion. A total of 88 patients met the inclusion criteria for this study: 28 underwent ARCR+Mfx and 60 underwent isolated ARCR. The mean final follow-up was 74.11 ± 33.57 months for the ARCR+Mfx group and 72.87 ± 11.46 months for the ARCR group (P = .80). There were no differences in baseline patient characteristics or preoperative outcome scores between groups. Postoperatively, both groups experienced statistically significant improvements in all outcome scores (P < .0001 for all). However, the ARCR+Mfx group had significantly worse VAS pain (1.89 ± 2.22 vs 1.03 ± 1.70; P = .05), SANE (85.46 ± 12.99 vs 91.93 ± 12.26; P = .03), and ASES (86.25 ± 14.14 vs 92.85 ± 12.57; P = .03) scores. At the final follow-up, 20 (71.43%) patients in the ARCR+Mfx group and 53 (88.33%) patients in the ARCR group were able to remain on unrestricted active-duty military service (P = .05). Concomitant ARCR+Mfx led to statistically and clinically significant improvements in patient-reported outcome measures at the midterm follow-up. However, patients who underwent ARCR+Mfx had significantly worse outcomes and were less likely to return to active-duty military service than those who underwent isolated ARCR. The study findings suggest that ARCR+Mfx may be a reasonable option for young, active patients who are not candidates for arthroplasty.

Similar return to sport between double cortical button and docking techniques for ulnar collateral ligament reconstruction in baseball players

A double cortical button technique for ulnar collateral ligament reconstruction (UCLR) has advantages including significant control over graft tensioning, less concern about graft length and minimized risk of bone tunnel fracture compared to traditional UCLR techniques. This double cortical button technique was recently found to be non-inferior in mechanical performance compared to the traditional docking technique regarding joint strength, joint stiffness, and graft strain. However, clinical outcomes have not been compared between these UCLR techniques. Therefore, the purpose of this study was to determine whether baseball players who underwent UCLR with a double cortical button (double button) technique have similar return to sport (RTS) outcomes compared to baseball players who underwent UCLR with the traditional docking (docking) technique. Baseball players that underwent primary UCLR from 2011-2020 across two institutions were identified. Included patients were contacted to complete a follow-up survey evaluating reoperations, RTS, and functional outcome scores. Functional outcome surveys include the Kerlan-Jobe Orthopaedic Clinic (KJOC) score, Conway-Jobe score, Andrews-Timmerman (AT) elbow score, and the Single Assessment Numeric Evaluation (SANE) score. Overall, 78 male baseball players (age: 18.9±2.4 years) with an average follow-up of 3.1±2.4 years were evaluated, with 73 of the players being baseball pitchers. Players in the double button group more frequently received palmaris longus autografts (78% vs. 30%) and less frequently received gracilis autografts (22% vs. 58%) compared to players in the docking group (p=0.001); however, all other demographic factors were similar between groups. All players in the double button group were able to RTS in 11.1±2.6 months, while 96% of players in the docking group were able to RTS in 13.5±3.4 months (p>0.05). All post-operative outcomes and patient-reported outcomes were statistically similar between groups, and remained similar after isolating pitchers only and after separating partial-thickness from full-thickness UCL tears (all p>0.05). Return to sport and other post-operative outcomes may be similar between baseball players who underwent UCLR with the double button technique and the docking technique. While future research may be necessary to strengthen clinical recommendations, these findings provide the first clinical outcomes in light of a recent cadaveric study finding similar elbow strength, joint stiffness, and graft strain compared to the docking technique.

Early results of reverse total shoulder arthroplasty using a patient-specific baseplate to address severe glenoid deficiency

Background The purpose of this study was to describe outcomes of patients undergoing reverse total shoulder arthroplasty (rTSA) using a patient-specific, custom glenoid component to address severe glenoid deficiency. Methods Retrospective chart review identified patients at a single institution undergoing rTSA using the glenoid vault reconstruction system (VRS) between 2017 and 2022. Radiographic evaluation, range of motion and patient-reported outcome (PRO) measures, complications, and re-operations were assessed. Results Fourteen shoulders were included. There was 100% implant survivorship of the glenoid baseplate at mean follow-up of 26.6 months. Mean range of motion improved in forward elevation (62–106 degrees), abduction (41–100 degrees), and external rotation (11–36 degrees). In 7 of 13 patients available for PRO collection, the mean final Visual Analog Pain Scale (VAS) score was 1.29, Single Assessment Numeric Evaluation (SANE) score was 72.14, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score was 77.14, and Penn Shoulder score was 72.26. Conclusions Use of this custom glenoid resulted in encouraging clinical and radiographic outcomes, with no failures in implant survivorship seen at early follow-up. Larger prospective studies with longer-term follow-up should be undertaken in order to better determine the efficacy and longevity of this implant. Study Design Retrospective case series; Level of evidence, 4.

Patient-reported outcomes of arthroscopic repair for partial or full-thickness upper third subscapularis tendon tears with open sub-pectoral biceps tenodesis: minimum 10-year outcomes

Although short-term results are promising, there are limited data for long-term results of arthroscopic SSC repair. The purpose of this study is to report minimum ten-year outcomes of primary arthroscopic repair of isolated partial or full-thickness tears of the upper third of the subscapularis (SSC) tendon. Patients who underwent arthroscopic repair of isolated upper third SSC tears, Lafosse type I (>50% of tendon thickness) or type II were included. Surgeries were performed by a single surgeon between 11/2005 and 8/2011. Patient reported outcome (PRO) measures were prospectively collected and retrospectively reviewed at minimum follow-up of 10 years. PROs utilized included the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation Score (SANE), Quick Disabilities of the Arm, Shoulder and Hand Score (QuickDASH), the Short Form 12 physical component summary (SF-12 PCS), return to activity, and patient satisfaction. A sub-analysis of patient age and outcomes was performed. Retears, revision surgeries, and surgical complications were recorded. In total, 29 patients with isolated upper third SSC repairs were identified. After application of exclusion criteria, 14 patients were included in the final analysis. Follow-up could be obtained from 11 patients. The mean age at surgery was 52.7 years (range: 36-72) and the mean follow-up was 12 years (range 10-15 years). The ASES score improved from 52.9 ± 21.8 preoperatively to 92.2 ± 13.7 postoperatively (p<.001). Regarding the SANE and QuickDASH Scores, only postoperative data was available. Mean postoperative SANE, QuickDASH, and SF-12 PCS scores were 90.27 ± 10.5, 14.6 ± 15.5, and 49.2 ± 6.6, respectively. Median patient satisfaction was 10 (range 6-10). Patients reported improvements in sleep, activities of daily living, and sport. There was no correlation between patient age and clinical outcome (p>.05). No patients underwent revision surgery for a SSC retear. Arthroscopic repair of upper third SSC tendon tears leads to improved clinical scores and high patient satisfaction at minimum 10-year follow-up. The procedure is durable, with no failures in the presented cohort.

Functional and Sport-Specific Outcome Following Traumatic First-Time Shoulder Dislocation and Arthroscopic Surgical Repair in Rock Climbers.

Traumatic shoulder dislocations rank among the most common shoulder injuries in climbers, with rising numbers over the last years. The objective of this study was to analyze the outcome following traumatic first-time shoulder dislocation and subsequent surgical treatment in this population. In a retrospective study, climbers who experienced a traumatic shoulder dislocation were treated with an arthroscopic repair of the labrum-ligament complex (LLC). The functional outcome was assessed with a standardized questionnaire and clinical examination, including the Constant Murley and Single Assessment Numeric Evaluation scores. The sport-specific outcome was analyzed using the Union Internationale des Associations d'Alpinisme (UIAA) scale of difficulty and a sport-specific outcome score. The functional and sport-specific outcome for 27 climbers (20 men; 7 women; 3 with bilateral injuries; age, 34±11 [17-61] y; data presented as mean±SD [range]) was assessed 53±29 (12-103) mo after surgery. The postoperative Constant Murley score was 95±8 (67-100) points. At follow-up, 93% (n=25) of patients had started climbing again. Twenty-one climbers (78%) reached a climbing level within the range of ±0.33 UIAA grades of their initial capability or even exceeded their preinjury grade. Only 7% (n=2) of the patients had a recurrent shoulder dislocation, leading to a secondary surgery, and, therefore, required ongoing postoperative treatment at the time of follow-up. Arthroscopic repair of the LLC following first-time traumatic shoulder dislocation in climbers shows a good outcome and a low recurrence rate. After surgery, most patients are able to regain a high level of rock-climbing ability.

Tunnel-free acromioclavicular joint reconstruction is associated with improved initial reduction and higher patient satisfaction

Many surgical techniques have been described for acromioclavicular (AC) joint reconstruction. Creation of bone tunnels through the clavicle or coracoid has been shown to be a risk factor for fracture. Use of an AC reconstruction technique that does not create bone tunnels may obviate this risk. This study aims to evaluate clinical outcomes of AC joint reconstruction using a tunnel-free technique compared to reconstruction using a cortical button and clavicular drill holes. Consecutive patients who underwent AC joint reconstruction by a single surgeon in a subspecialty referral practice were included. One group of patients received cortical button fixation (button group), in which sutures were passed around the coracoid, brought up through a drill hole in the clavicle, and tied over a cortical button. The other group of patients received tunnel-free fixation, in which a self-locking tape suture was passed in a cerclage fashion around the base of the coracoid and the clavicle and tensioned with a tensioning device (cerclage group). Both groups underwent reconstruction of the coracoclavicular (CC) ligament and AC joint capsule using tibialis anterior allograft. Patient-reported outcome scores and satisfaction were collected and compared between groups. Radiographs were reviewed to evaluate CC ligament distance and loss of reduction. Twenty-two patients were included in the study (button n= 10, cerclage n= 12). Preoperative demographics and injury characteristics were not different between groups. Average radiographic follow-up was not different between groups (button: 231 days, cerclage: 105 days). Postoperative American Shoulder and Elbow Surgeons, visual analog scale, and Single Assessment Numeric Evaluation scores were similar between groups. Two postoperative clavicle fractures were sustained in the button group. These occurred through clavicular drill holes and were preceded by tunnel widening. No fractures occurred in the cerclage group. CC distance at initial follow-up was significantly less in the cerclage group (button: 11.2 ± 4.5 mm, cerclage: 7.0 ± 2.9 mm, P=.023). Loss of reduction was similar throughout the postoperative period (button: 4.3 ± 2.6 mm, cerclage: 4.8 ± 4.1 mm, P >.05. Forty percent of patients were unsatisfied with their clavicle after button fixation (n= 4/10), compared with zero after cerclage fixation (n= 0/12, P=.03). Reasons for dissatisfaction were fracture (n= 2) and persistent cosmetic deformity (n= 2). Tunnel-free AC joint reconstruction is associated with improved initial radiographic appearance and patient satisfaction compared to single cortical button fixation. Postoperative clavicle fracture and persistent cosmetic deformity drive patient dissatisfaction, which may be minimized by avoiding clavicular drill holes and using a tensioned self-locking cerclage suture to improve initial reduction.

Arthroscopic Scapulothoracic Bursectomy with and without Superomedial Angle Scapuloplasty: A Comparison of Patient-Reported Outcomes.

Operative treatment of scapulothoracic bursitis most commonly comprises arthroscopic scapulothoracic bursectomy with or without partial superomedial angle scapuloplasty. There is currently no consensus regarding if or when scapuloplasty should be performed. Prior studies are limited to small case series and optimal surgical indications are not yet established. The purposes of this study are to 1) retrospectively review patient reported outcomes of arthroscopic treatment of scapulothoracic bursitis and, 2) compare outcomes between scapulothoracic bursectomy alone and bursectomy with scapuloplasty. The authors hypothesized that bursectomy with scapuloplasty would provide superior pain relief and functional improvement. All cases of scapulothoracic débridement with or without scapuloplasty completed at a single academic center from 2007 through 2020 were reviewed. Patient demographics, symptomatology, physical exam findings, and corticosteroid injection response data were collected from the electronic medical record. Visual analog scale (VAS) pain, American Shoulder and Elbow Surgeons (ASES) scores, Simple Shoulder Test (SST), and SANE scores were collected. Comparisons between bursectomy alone and bursectomy with scapuloplasty groups were made using Student's t-test for continuous variables and Fisher's exact test for categorical variables. Thirty patients underwent scapulothoracic bursectomy alone, and 38 patients underwent bursectomy with scapuloplasty. Final follow-up data was completed for 56 of 68 (82%) cases. Final postoperative VAS pain scores (3.4±2.2 vs. 2.8±2.2 (p=0.351)), ASES scores (75.8±17.7 vs. 76.5±22.5 (p=0.895)), and SST scores (8.8±2.3 vs. 9.5±2.8 (p=0.340)) were similar between the bursectomy only and bursectomy with scapuloplasty groups, respectively. Both arthroscopic scapulothoracic bursectomy and bursectomy with scapuloplasty are effective treatments for scapulothoracic bursitis. Operative time is shorter without scapuloplasty. In this retrospective series, these procedures have similar outcomes regarding shoulder function, pain, surgical complications, and rates of subsequent shoulder surgery. Further studies with a focus in 3D scapular morphology may help optimize patient selection for each of these procedures.

Validation of the ACL-RSI Scale in Pediatric and Adolescent Patients

Background: The Anterior Cruciate Ligament–Return to Sport after Injury (ACL-RSI) scale is a 12-item questionnaire assessing psychological readiness to return to sport after anterior cruciate ligament reconstruction. It has been validated for use in adults in multiple languages and in an abbreviated 6-question short form. Additionally, literature has been published using this scale in pediatric and adolescent populations, however it has not yet been validated for use with them. Purpose: To validate the ACL-RSI scale for use with pediatric and adolescent patients. Study Design: Cohort study (Diagnosis); Level of evidence, 2. Methods: Scores of 6- and 12-item ACL-RSI scales for patients undergoing return-to-sport readiness testing 6 to 8 months after anterior cruciate ligament reconstruction were analyzed. Convergent validity testing was performed against the International Knee Documentation Committee (IKDC)/Pediatric IKDC score, Single Assessment Numeric Evaluation (SANE) score, and peak torque asymmetry of knee flexion and extension using Spearman correlations. Discriminant validity testing was performed against age (Spearman correlation), body mass index (Spearman correlation), and sex (Mann-Whitney U test). Reliability testing was performed by calculating Cronbach’s alpha. Floor and ceiling effects were assessed by calculating the number of minimum and maximum scores in the cohort. Results: A total of 51 patients were included in the final analysis. The mean age at surgery was 15.2 ± 2.2 years, and 51.0% were female. The 6- and 12-item ACL-RSI scales demonstrated a strong significant positive correlation with IKDC/Pediatric IKDC scores (R = 0.723 and 0.717, respectively; P < .001) and moderate significant positive correlation with Single Assessment Numeric Evaluation scores (R = 0.516 and 0.502, respectively; P < .001) Age at surgery, body mass index, and sex were not correlated with either ACL-RSI scale. Cronbach’s alpha values of the 12- and 6-item ACL-RSI scales in this population were 0.959 and 0.897, respectively. For both the 12- and the 6-item ACL-RSI scales, no floor or ceiling effects were found as the minimum score (0) was not observed in either version, and the maximum score (100) was only observed twice (3.9%) in both versions. Conclusion: The ACL-RSI scale is valid to use with pediatric and adolescent patients. The 6-item scale may be a better choice because it has fewer redundancies and minimizes the risk of questionnaire fatigue.

Efficacy and Long-Term Outcomes of Intra-Articular Autologous Micro-Fragmented Adipose Tissue in Individuals with Glenohumeral Osteoarthritis: A 36-Month Follow-Up Study.

Glenohumeral osteoarthritis (GOA) is associated with disabling shoulder pain that affects everyday life. Its management comprises various treatment approaches, both conservative and surgical. Regenerative medicine has gained a major role in the conservative treatment of osteoarthritis. Intra-articular injection of adipose-derived mesenchymal stem cells (ADMSCs) is a widely used regenerative medicine approach. The aim of this retrospective study was to report the safety and clinical outcomes of intra-articular injection of ADMSCs in patients with GOA over 36-months. This retrospective observational study involved patients with chronic shoulder pain resistant to standard conservative treatment and a diagnosis of concentric GOA, who received an intra-articular injection of autologous micro-fragmented adipose tissue (μFAT). The values of the Constant-Murley score (CMS), the visual analog scale (VAS), and the simple shoulder test (SST), collected at baseline and at 12, 24, and 36 months, were analyzed to assess treatment efficacy. The single assessment numeric evaluation (SANE) was used to rate patient satisfaction. The Friedman test was used to compare observations of CMS, VAS, and SST values repeated on the same subjects. The significance threshold was set at 0.05. The participants were 65 patients with a mean age of 54.19 years and a nearly equal gender distribution. Most had mild concentric GOA classified as Samilson-Prieto grade 1. The mean follow-up duration was 44.25 months. The postoperative clinical scores showed significant improvement. At 36 months, the CMS was 84.60, the VAS score was 3.34, and the SST score was 10.15 (all p < 0.0001). The SANE score at 36 months indicated that 54 patients (83.08%) were completely satisfied with the treatment. ADMSC treatment exerted favorable effects on the clinical outcomes of patients with GOA, providing pain relief and improving shoulder function. Our data support its use as a conservative treatment option for osteoarthritis.

Statistical Literacy in Hand and Upper-Extremity Patients

Statistical literacy is the ability of a patient to apply basic statistical concepts to their health care. Understanding statistics is a critical component of shared decision making. The purpose of this investigation was to define levels of statistical literacy in an upper-extremity (UE) patient population. We aimed to determine if patient demographics would be associated with statistical literacy. An electronic survey was administered to a consecutive series of UE patients at a single institution. We recorded baseline demographics, Single Assessment Numeric Evaluation scores, the Berlin Numeracy Test (BNT), and General Health Numeracy Test. We also included a surgical risk question, which asked: "Approximately 3% of patients who get carpal tunnel surgery develop an infection. If 100 patients get this surgery, how many would you expect to develop an infection?" A covariate-controlled adjusted odds ratio reflecting the association between each statistical literacy outcome measure and patient characteristics was reported. A total 254 surveys were administered, 148 of which were completed and included. Fifty percent of respondents had a high-school education or less. For the BNT, 78% scored in the bottom quartile, and 52% incorrectly answered all questions. For the General Health Numeracy Test, 34% answered 0 or 1/6 questions correctly. For the surgical risk question, 24% of respondents answered incorrectly. Respondents who had a college or graduate degree had 2.62 times greater odds (95% confidence interval, 1.09-6.32) of achieving a BNT score in a higher quartile than patients who did not have a college or graduate degree. Overall levels of statistical literacy are low for UE patients. When engaging in management discussions and shared decision making, UE surgeons should assume low levels of statistical literacy. Consideration of alternative formats, such as frequencies, video-based materials, and pictographs, may be warranted when discussing outcomes and risks of surgical procedures.

Does the addition of post-operative gabapentin reduce the use of narcotics after orthopedic surgery?

ABSTRACT Objectives To evaluate the efficacy of post-operative gabapentin administration as an analgesic agent and its effect on narcotic use after orthopedic surgery in an outpatient sports medicine practice by comparing patients prior to and after initiating the routine use of gabapentin as part of a standardized post-operative pain medication regimen. We hypothesized that adding gabapentin to a multimodal post-operative pain regimen would decrease the number of requested pain medication refills and have no detrimental effect on Visual Analogue Scale and Single Assessment Numerical Evaluation scores at these early post-operative visits. Methods All outpatient surgical patients, <90 years of age, undergoing outpatient orthopedic surgery by the study’s senior author were included between 08/05/2021 and 02/22/2022. Patients were allowed 1 narcotic refill post-operatively and only in the first 3 weeks. The primary outcome was difference in percentage of patients who requested a narcotic refill within 3 weeks post-op. Two- and 6-week Visual Analogue Scale and Single Assessment Numerical Evaluation scores, and baseline health and demographic data. T-tests were run on continuous variables, Chi-Square or Fisher’s Exact Test were run on dichotomous variables, and Mann–Whitney U test was run on all other categorical variables. Statistical significance was set at P < .05 for all tests. Results There was a significant difference in narcotic refills at 3 weeks: 23 pre-gabapentin patients and 9 post-gabapentin patients (22.8% vs 9.0%, respectively: P = .006). There were no differences between 2- and 6-week Visual Analogue Scale and 2-week Single Assessment Numerical Evaluation scores. There was a significant difference in 6-week SANE between groups: mean difference = 6.4 (P = .027) though less than the established MCID. Conclusion Addition of gabapentin to a post-operative multimodal pain regimen reduced the use of narcotics after orthopedic sports medicine surgeries while also providing equivalent pain control.

Primary Anterior Cruciate Ligament Reconstruction with Suture Tape Augmentation: A Case Series of 252 Patients.

Anterior cruciate ligament reconstruction (ACLR) using suture tape augmentation to internally brace is a relatively new technique. The primary goal of this study was to prospectively collect patient-reported outcomes (PROs) and surgical history from patients who underwent primary ACLR with internal bracing to determine if internal bracing resulted in a low graft failure rate while maintaining acceptable PROs. A total of 252 patients with a mean age of 23.6 years (95% confidence interval [CI]: 22.1-25.1) and a mean follow-up of 37.9 months (95% CI: 35.8-40.0) were included in this study. Patients who underwent primary ACLR with internal brace augmentation between July 12, 2016 and July 31, 2021 were eligible. A total of 222 patients were contacted via telephone and administered the visual analog scale (VAS), the single assessment numeric evaluation (SANE), the Lysholm knee score scale, and, if applicable, the short version ACL return to sport after injury (SV-ACL-RSI) survey. Additionally, patients were asked to give an updated orthopaedic history. Thirty additional patients were included from either our institution's registry or by completing their surveys in-office or by e-mail. The minimal clinically important difference (MCID) and patient-acceptable symptom states (PASS) were calculated based on our patient population and applied to each individual patient. The patients' electronic health record (EHR) was searched for pre- and postoperative clinical data including KT-1000 arthrometer measurements. Two patients (0.8%) had subsequent graft failures and one patient (0.4%) required a revision surgery. MCID was achieved in 242 patients (96.0%) for the Lysholm, 227 patients (90.1%) for the SANE, and 146 patients (57.9%) for the VAS. PASS was achieved in 214 patients (84.9%) for the Lysholm, 198 patients (78.6%) for the SANE, and 199 (80.0%) patients for the VAS, postoperatively. Of note, 65 patients (25.8%) exceeded the PASS threshold for the VAS preoperatively. A total of 127 patients (84.4%) met the cutoff of ≥60/100 for the SV-ACL-RSI survey postoperatively. Postoperative KT-1000 measurements showed near-identical side-to-side differences at both the 13.6-kg pull and manual maximum pull. When stratifying patients based on age at the time of surgery, it was noted that patients younger than 25 years had significantly higher SANE scores (91.6 [95% CI: 90.2-92.9] vs. 82.6 [95% CI: 79.0-86.2]; p < 0.0001) and lower VAS pain scores (0.7 [95% CI: 0.5-0.8] vs. 1.2 [95% CI: 0.8-1.5]; p = 0.004). Primary ACLR with internal bracing led to acceptable patient outcomes and a graft failure rate of less than 1%. LEVEL OF EVIDENCE:: case series, IV.
