Short-Term Clinical Results of Middle Trapezius Tendon Transfer with Achilles Tendon Allograft for Irreparable Supraspinatus Tears

BackgroundAmong emerging options, Middle Trapezius Tendon (MTT) transfer has shown promise, particularly in isolated supraspinatus irreparable rotator cuff tears (ISIRCTs) and nonarthritic shoulders unsuitable for reverse total shoulder arthroplasty. This study aims to assess clinical and radiological results of MTT transfer utilizing an Achilles tendon allograft for ISIRCTs. MethodsWe retrospectively reviewed patients who received MTT transfer using Achilles tendon allograft for ISIRCTs between May 2020 and August 2021. Clinical assessments using pain VAS, Constant, ASES, UCLA, and SANE score were assessed pre- and postoperatively. Active Range of Motion (aROM) were obtained, and radiologic assessments included AHD, Hamada grade, and MTT integrity. Results18 patients were involved with mean age of 63.8 ± 7.1, followed for an average of 25.4 ± 4.4 months. Significant improvements were observed in pain relief (VAS:4.7±1.5 to 1.6±0.9, P<.001), shoulder function (Constant: 53.1±11.1 to 70.0±15.1, ASES: 57.7±13.5 to 78.2±17.0, UCLA: 13.6±4.5 to 22.0±6.4; all P<.001), and patient satisfaction (SANE: 51.3±14.1 to 73.7±15.0, P<.001). Active range of motion significantly improved in Forward elevation (FE) and abduction (ABD). Radiologic assessments showed no significant change in AHD and Hamada grade, with p-values of 0.503 and 0.260, respectively. ConclusionMTT transfer using Achilles tendon allograft showed improvement in pain relief, clinical scores, and active FE and ABD in patients with ISIRCTs. However, the validation of its effectiveness necessitates multicenter and long-term studies.

Minimum 10-year Follow-up after Open Reduction and Internal Fixation of Radial Head Fractures Mason Type II and III

The treatment of complex radial head fractures remains controversial with open reduction and internal fixation (ORIF), radial head arthroplasty, and radial head excision being the most common treatment options. While ORIF is the preferred treatment strategy for Mason type II fractures, the optimal treatment of Mason type III fractures is debated. To report minimum 10-year outcomes after ORIF of Mason type II and type III radial head fractures. We hypothesized that both Mason Type II and Type III fracture patients would demonstrate satisfactory clinical outcomes at minimum 10-year follow-up. All patients with Mason type II or III radial head fractures who were treated with ORIF by a single surgeon between 2005 and 2010 were included. Fractures with significant bone defects were treated with bone grafts and elbow ligament injuries were treated with either primary ligament repair or reconstruction. Patient reported outcome (PRO) questionnaires were administered at the time of last clinical follow-up and at a minimum of 10 years postoperatively. Twenty-four patients, including 13 male and 11 female patients with an average age of 39 (range 19-60) at the time of surgery met inclusion criteria. Thirteen patients suffered from Mason type II and 11 patients from Mason type III fractures. At initial follow-up, 21 out of 24 fractures (88%) demonstrated radiographic union. Three non-unions, 2 of which were Mason type III fractures, were treated with revision ORIF and iliac crest bone grafting. 11 patients developed postoperative elbow stiffness and required capsular release surgery. At last clinical follow-up, average flexion was 139 degrees, average extension was 4 degrees, average supination was 77 degrees, and average pronation was 81 degrees. The median DASH score was 7 (ranging from 0 - 32). Minimum 10-year follow-up (mean: 14.6 years) was collected on 18 of 24 (75%) of the patients. At a minimum of 10 years postoperatively, the median QuickDASH score was 4.5 (range: 0 to 25) and the median SANE score was 96.5 (range: 75-100). Median satisfaction with the surgical outcome was 10/10 (range: 3-10). ORIF of Mason type II and III radial head fractures results in high union rates with good functional outcomes at a mean of 14.6 years postoperatively. The study results suggest that ORIF of Mason type II and III radial head fractures leads to long-term positive functional outcomes.

Improved patient reported outcomes with knotless double-row rotator cuff repair with and without lateral row biceps tenodesis at 2- and 5-years

BackgroundThe purpose of this study is to report outcomes of an arthroscopic knotless double-row (DR) rotator cuff repair (RCR) technique at 2- and 5- years postoperatively, and to compare clinical outcomes in patients undergoing knotless DR RCR with incorporated lateral row biceps tenodesis vs. those without lateral row biceps tenodesis. MethodsAll primary RCR surgeries were performed by a single surgeon at a single institution using a knotless transosseous equivalent (TOE) technique. The postoperative rehabilitation protocol was standardized for all patients. The primary outcomes collected included ASES Function, ASES Index, SANE, SST, VR-12 physical and mental, and VAS scores. ResultsThree hundred forty-two patients met inclusion criteria, of which 262 patients underwent isolated RCR and 61 underwent RCR with a concomitant lateral row biceps tenodesis, 15 underwent RCR with concomitant tenotomy and 4 had RCR with débridement of the biceps. Significant improvements in VAS, ASES, SANE, SST, and VR-12 scores were observed at all time points in all patient groups. No statistically significant differences in outcomes were noted in patients undergoing RCR with a lateral row tenodesis vs. those undergoing RCR alone. Similarly, no differences were seen when stratified by age, sex, BMI, Worker’s Compensation (WC) status, smoking, and diabetes mellitus (DM). Based on ASES, 81% of patients met minimum clinically important difference (MCID), and 64% met maximum outcome improvement (MOI) at 1-year postoperatively. ConclusionKnotless DR TOE arthroscopic RCR significantly improves patient-reported clinical outcomes at 1-, 2- and 5-year follow-ups. These results are reflected in clinical practice because 80% achieve MCID postoperatively. Patient-related factors, including BMI, age, sex, WC, and DM do not significantly affect patient-reported outcomes in the first 5 years after surgery. Smokers have worse baseline scores which persist at 2-year follow-up. Lastly, adding an arthroscopic lateral row biceps tenodesis in knotless DR TOE arthroscopic RCR provides similar clinical outcomes to knotless DR TOE arthroscopic RCR without biceps tenodesis.

Increased glenoid baseplate retroversion improves internal rotation following reverse shoulder arthroplasty

BackgroundInternal rotation after reverse shoulder arthroplasty (RSA) is often unchanged or minimally improved. The primary purpose of this study was to investigate the effects of glenoid baseplate version on postoperative internal rotation. The secondary purpose to investigate the effects of baseplate retroversion on external rotation (ER) and patients reported outcomes (PROs). MethodsA retrospective review was performed on a prospectively maintained multicenter database of patients who underwent primary RSA using a 135° humeral prosthesis and lateralized glenoid with minimum 2-year clinical follow-up. Preoperative and postoperative radiographs were reviewed by two independent observers who assessed preoperative glenoid version and postoperative glenoid baseplate version. Patients were stratified by postoperative retroversion (<10°, 10-19° or >20°) and change in version from preoperative to postoperative (ΔRV). Primary outcomes were internal rotation with the arm at 90° (IR90) and internal rotation estimated to nearest spinal level (IRspine). Secondary outcomes were active external rotation in adduction (ER0), active external rotation with arm at 90° (ER90), forward flexion (FF), and PROs. Linear regression analyses and one-way analysis of variance (ANOVA) analyses were used for comparisons. Results274 patients with a mean of 71 years of age were included in the study. Patients with >10° of postoperative baseplate retroversion gained 20° of IR90 (p=0.005) without loss of ER90 (p<0.001) compared to patients with <10° of baseplate retroversion. More than 10° of postoperative baseplate retroversion was associated with significantly improved Constant-Murley scores (41.5, p=0.007) and SANE scores (45.4, p=0.047) compared to patients with less than <10° of baseplate retroversion. Patients with a ΔRV increase of > 10° had significantly improved IR90 (p=0.031) without loss of ER90 (p=0.019). There was no correlation between ΔRV and IRspine, ER0 or FF, or PROs. ConclusionWith a 135° and lateralized glenoid, postoperative baseplate retroversion of >10° was associated with significantly improved IR90, ER90, Constant-Murley and SANE scores at 2 years follow-up compared to <10° retroversion. Additionally an increased ΔRV from pre- to postoperative appears to improve IR90 without limiting ER0 or FF. While baseplate retroversion does not improve IRspine, overall function appears to be improved and therefore consideration may be given to accepting retroversion or intentionally retroverting the baseplate if fixation allows.

Subacromial injection of platelet-rich plasma provides greater improvement in pain and functional outcomes compared to corticosteroids at 1-year follow-up: a double-blinded randomized controlled trial

BackgroundStudies evaluating the results of platelet-rich plasma (PRP) for the treatment of rotator cuff tendinopathy (RCT) have demonstrated conflicting results and have been confounded by small patient samples, the absence of a control group, the combined analysis of isolated tendinopathies and rotator cuff tears, insufficient reporting of PRP preparations, The purpose of this study was to perform a randomized controlled trial comparing platelet-rich plasma (PRP) with standard corticosteroid (CS) injections in providing pain relief and improved function in patients with rotator cuff tendinopathy. MethodsThis was a double-blind RCT at a single center. We evaluated patients between 18 and 50 years old who had both a clinical and magnetic resonance (MRI) diagnosis of supraspinatus tendinopathy refractory to conservative treatment. A total of 50 patients received PRP treatment, whereas 50 patients received a corticosteroid, as a control group. Patients completed patient-reported outcome assessments at baseline and at 1, 3, 6 and 12 months after injection. The primary outcome was improvement in the VAS score for pain. Secondary outcomes included changes in ASES score, SANE score and the Pittsburgh Sleep Quality Index (PSQI). Treatment failure was defined as persistent pain at 3 months which required a subsequent injection. ResultsThe mean age was 27.7 (±7.4). All the patients completed 12 months clinical follow-up. At 12 months, patients in the PRP group showed a significantly greater improvement in the VAS than patients in the CS group 1.68(0.6) vs 2.3(1.0) (p<0.001). As well, at 12 months follow-up, the 3 scores evaluated were significantly higher in patients treated with PRP than in patients treated with CS ASES 89.8 (6.3) vs 78.0 (8.6) (p<.001); SANE 89.2 (6.3) vs 80.5 (9.6) (p< .001) and PSQI 2.72 (0.6) vs 4.02 (1.7) (p< .001)The overall failure rate, was significantly higher in the CS group (30%) than in the PRP group (12%) (p<0.01) ConclusionOne subacromial PRP injection in patients with rotator cuff tendinopathy showed significantly superior and sustained pain-relieving and functional improvements compared with one corticosteroid subacromial injection assessed by 4 patient-reported outcome scales at 12 months of follow-up. Moreover, the overall failure rate, was significantly higher in the CS group than in the PRP group.

Correlation between the optimal screening for prediction of referral and outcome yellow flag tool and patient-reported legacy outcome measures in patients undergoing shoulder surgery

BackgroundThe Optimal Screening for Prediction of Referral and Outcome Yellow Flag (OSPRO-YF) Tool is a 10-item multidimensional screening tool utilized to evaluate pain-related psychological traits in individuals with musculoskeletal pain conditions. The validity of postoperatively collected OSPRO-YF is unclear. This study sought to assess validity of the OSPRO-YF by comparing it to PRO scores in both pre- and postoperative settings. HypothesisThe authors hypothesized that OSPRO-YF overall score would correlate with shoulder and global function PROs at pre- and postoperative timepoints. MethodsA review of 101 patients undergoing shoulder surgery by one sports medicine orthopedic surgeon at a large academic institution was conducted. 90 and 54 patients had complete pre- and postoperative PRO responses. OSPRO-YF, American Shoulder and Elbow Surgeons Evaluation Form (ASES), and Patient-Reported Outcomes Measurement Information System Computer Adaptive Test (PROMIS-CAT) were routinely administered before and after surgery at the senior author’s clinic visits. Concurrent validity of OSPRO-YF at either timepoint was assessed by comparing scores with PROs cross-sectionally using Pearson correlations and multiple comparison corrections. ResultsPreoperatively, higher OSPRO-YF total score was associated with greater concurrent PROMIS-CAT Pain Interference (r=0.43; p<0.01) and Depression (r=0.36; p=0.05) and lower ASES (r=-0.34; p<0.01). Higher postoperative OSPRO-YF was also associated with greater concurrent PROMIS-CAT Pain Interference (r=0.43; p<0.01) and Depression (r=0.36; p<0.01) and lower ASES (r=-0.34; p=0.01). ASES had strong correlation with SANE and Pain scores at both pre- and postoperative timepoints. SANE was not significantly associated with OSPRO-YF total score or number of YFs at either timepoints. ConclusionThe study findings support the clinical validity of the 10-item OSPRO-YF tool when administered before or after shoulder surgery. For patients exhibiting suboptimal recovery or those identified as high risk at initial screening, assessment of pain-related psychological distress postoperatively may be particularly beneficial in guiding rehabilitation.

Solid organ transplant patients do well after shoulder arthroplasty: a propensity matched analysis

Solid organ transplant (SOT) recipients are commonly prescribed immunosuppressive therapies which may predispose patients to higher infection and complication rates following total shoulder arthroplasty. This article aims to analyze the effects SOT and subsequent immunosuppressive regimens have on the functional and patient-reported outcomes of total shoulder arthroplasties. A single institution, multisurgeon retrospective case-control study investigating the functional and patient-reported outcomes of shoulder arthroplasty after SOT was conducted between the years of 2010 and 2020. To be included in the study, patients must have undergone SOT prior to primary total shoulder arthroplasty. A 4:1 match-paired control group lacking SOT prior to arthroplasty was then constructed. Thirty-four SOT patients (18 males and 16 females) and 136 control patients (77 male and 59 female) were included in the study. Patients were analyzed who underwent SOT prior to shoulder arthroplasty, with outcomes compared to controls that only underwent arthroplasty. The primary outcomes include range of motion and strength in forward elevation, external rotation, and internal rotation, and patient reported outcomes. There was no significant difference in improvement for range of motion and strength between the 2 cohorts, but within each cohort, improvement was statistically significant. In the SOT patients, forward elevation improved by 56° ± 52°, external rotation increased by 13° ± 20°, and internal rotation increased by 2 vertebral levels. In the non-SOT patients, forward elevation improved by 45° ± 51°, external rotation increased by 16° ± 25°, and internal rotation increased by 3 vertebral levels. SOT patients had equivocal visual analog scale pain and Simple Shoulder Test scores but lower American Shoulder and Elbow Surgeons (59±13 vs. 79±2; P=.002) and SANE (61±30 vs. 84±17; P<.001) scores than non-SOT patients. Complication rates were not significantly higher in the SOT group (15% vs. 6%; P=.05), but incidence of surgical revisions was not significantly different (SOT=3%; non-SOT=5%; P=.59). Shoulder arthroplasty is a safe, effective surgical intervention for improving shoulder function in patients with a history of SOT. Despite being on chronic immunosuppressive regimens, our solid organ transplants had comparable clinical outcomes and revision rates, but higher complication rates.

Paper 23: Functional Stability Testing and Athletic Shoulder Performance Testing Higher in Patients Able to Return to Sport Following Arthroscopic Shoulder Stabilization

Objectives: There is a paucity of literature on return to sport functional testing following arthroscopic labral repair for shoulder instability leading to uncertainty of when it is safe to return to sport. Currently, the most commonly used evaluation metrics are time after surgery and less commonly range of motion and strength of operative extremity. There is currently no validated return to sport testing protocol after arthroscopic labral repair. The aim of this study was to compare elements of a proposed return to sport battery for those undergoing arthroscopic Bankart repair between those able to return to play and those who were not able to by 6 months. Methods: All patients who participated in athletics who underwent arthroscopic labral repair for shoulder instability from June 2021 to December 2022 with a fellowship trained orthopedic surgeon were eligible to participate. Study protocol was to undergo functional testing at 4 months post operatively and every 2 months thereafter until cleared for athletics. Functional testing included Closed Kinetic Chain Upper Extremity Stability Test (CKCUES), Posterior Shoulder Endurance Test (PSET), Strength via handheld dynamometry at various range of motion positions. The Athletic Shoulder Test (ASH) has two components- peak force in I, T, Y position (PEAK), and rate of force development in I, T, Y position (RATE). Absolute value as well as limb symmetry index (LSI) were compared. For each test, passing was determined to be greater than 90% symmetry with contralateral extremity. Tests that had a greater than 20% difference in pass rates between the not return to play group (NRTP) and the return to play (RTP) groups were considered to be predictive. Results: Overall, 22 patients with at least 6 months of follow up, completed functional testing battery, and cleared to return to play were included. Mean age was 19.8 years (range 11-44 years), with 12 males and 10 females, and the mean follow up was 11 months (6-24 months). Seventeen returned to play (RTP) at mean 6.3 months (range 4.5-23.1), five did not to return (NRTP). Mean SANE score was higher in RTP vs NRTP, 61 (range 25-95) vs 86.7 (60-100), p=0.03). Those that returned to sport met a mean of 6.25 of the 12 criteria at 4 months compared to 4.20 of those that did not return to sport (p-value = .22). At 4 months, RTP group passed several tests at higher rates than NRTP group - CKCUES (78% vs 0%), PEAK (62.5% vs 20%), RATE (50% vs 0%), and Shoulder Flexion strength (88.9% vs 50%). Other strength measurements were not significantly different between groups. Conclusions: CKCUES and ASH (PEAK and RATE) performance testing criteria were significantly higher at 4 months in patients who are able to eventually be cleared to return to sport compared to those that are not able to. Traditional strength testing did not demonstrate differences between groups. Therefore, we recommend that CKCUES testing and ASH testing with force plates should be incorporated in functional testing as early as 4 months.

Paper 21: Anatomic Medial Ulnar Collateral Ligament Reconstruction with Internal Brace Augmentation in Throwing Athletes

Objectives: Injury to the Medial Ulnar Collateral Ligament (MUCL) is a common setback experienced by many throwing athletes often requiring reconstruction with 12-18 months of rehabilitation. Current reconstructive techniques fail to anatomically restore the MUCL which may contribute to the prolonged course of rehabilitation. In recent years, we described an anatomic MUCL reconstruction with internal brace augmentation which demonstrated improved biomechanical strength when compared to the docking technique in cadaveric specimens. The purpose of this study was to evaluate the postoperative course of both amateur and professional throwing athletes that underwent anatomic MUCL reconstruction with internal brace augmentation. We hypothesized that throwers would return to the same level of play and that return to play (RTP) would be a shorter duration compared to current reported outcomes. Methods: In this surgical technique, the native MUCL is formally repaired. The graft and a suture tape are folded over a suspensory loop and secured in a socket of the medial epicondyle of the humerus to maximize tendon to bone contact. On the ulnar side, the graft and internal brace are secured proximally by two suture anchors on either side of the sublime tubercle and further secured across the sublime tubercle ridge distally to re-create the anatomic triangular insertion of the native ligament. All surgeries were performed by a single surgeon. Patient reported outcomes in addition to date of RTP, level of play, and functional outcomes were retrospectively gathered. All patients initially followed an Accelerated Rehabilitation Protocol and were converted to a Standard Paced protocol if setbacks were encountered. Results: A total of 26 baseball players underwent primary (n=23) or revision (n=3) MUCL reconstruction with the Anatomic Technique. Of these, 15 were professional and 11 were amateur athletes. 92% of throwers returned to play at a mean of 9.9 months following reconstruction. 89% were able to advance through the accelerated postoperative protocol without issues and 85% returned to the same role and level of play. Post injury KJOC scores improved from 41 to 86.9 and SANE scores improved from 32.5 to 95.5. No significant difference was identified in pre-injury versus post-reconstruction throwing velocity, ball spin rate, or horizontal/vertical ball movement. Conclusions: Anatomic reconstruction of the MUCL with internal bracing is a viable option for MUCL injuries. Advantages include increased tendon-bone contact of the reconstruction, multiple fixation points, and anatomic restoration of the MUCL. This technique allowed an expedited return to sport for these baseball athletes.

Pectoralis major tendon rupture repairs using intramedullary suture anchors shows high patient-reported outcomes in military service members

BackgroundIn the general population pectoralis major tendon ruptures are uncommon; however, it is a common injury in the military population. The military service members have greater physical demands than the general population. The purpose of this study is to critically assess the post-operative outcomes of pectoralis major tendon ruptures in military service members following a repair using intramedullary suture anchors. PurposeTo report outcomes of pectoralis major repairs utilizing intramedullary suture anchors in military service members. MethodsA retrospective chart review was performed between 2014 to 2022, identifying patients who underwent a pectoralis major rupture repair performed by the senior surgeon using intramedullary suture anchors. Records were reviewed for age, gender, mechanism of injury, chronicity, VAS, and SANE scores. Patients who had less than 1 year of follow-up were excluded from the study. During the study period, 18 patients underwent surgical repair of their torn pectoralis major, and 15 patients were greater than 1-year post-operative. Twelve of these 15 patients (80%) were successfully contacted, and patient reported outcomes were collected. ResultsA total of 12 patients (12 male, 0 female) with a mean age of 34.5 years, were identified. Average time from injury to surgery was 471.4 days. The average duration of follow-up was 3.7 years. There was a decrease in the preoperative average single repetition maximum (1RM) barbell bench press of 277 lbs to a postoperative average 1RM bench press of 225 lbs (p-value=0.03). The average change in average 1RM barbell bench press is a 19.04% decrease postoperatively. Postoperative SANE score was 80.8 and an ASES of 86.9. Seven patients (58.3%) stated that they were afraid to bench press at their previous weight due to fear of reinjury. None of the patients were medically discharged from the military due to limitations from their repaired shoulder. Ten patients (83%) reported that they were extremely satisfied with their shoulder function post-operatively. ConclusionRepair of the pectoralis major tendon ruptures using intramedullary suture anchors has high rates of return to duty, patient satisfaction and patient reported outcomes. Greater than half of the patients reported that they were afraid to bench press at their preinjury weight due to concerns of reinjury; the decrease in post-operative strength may be a result of the patients’ fear of reinjury rather than physiologic limitations.

No clinical difference in outcomes between inlay and onlay arthroscopic biceps tenodesis techniques during rotator cuff repair

BackgroundBoth inlay and onlay arthroscopic biceps tenodesis (ABT) are common procedures performed during rotator cuff repair. The inlay method involves creating a bone socket in the bicipital groove to secure the long head of the biceps tendon (LHBT) using an interference screw. The onlay method utilizes a suture anchor to secure the LHBT on the surface of the bicipital groove. Little is known on the long-term differences in patient reported outcomes (PROs) between these two techniques. The primary purpose of this study was to compare PROs of inlay versus onlay ABT with a minimum follow-up of two years. Secondary aims were to evaluate the impact of rotator cuff tear size on outcomes and compare rates of complications between the two techniques. MethodsA retrospective chart review was performed to identify patients who had an ABT during a full-thickness rotator cuff repair. Any symptom specific to the biceps were noted, including pain and cramping, Popeye deformity, or revision surgery. Complication rates were compared between groups. The VAS pain score, ASES, SANE, and VR-12 scores were compared at two years. The impact of rotator cuff tear size was analyzed by categorizing into small/medium or large/massive based on operative reports and arthroscopic images. ResultsThere were 165 patients identified (106 in the inlay group and 59 in the onlay group). No revision surgeries were performed secondary to the biceps tendon in either group. Eleven patients (10%) in the inlay group complained of biceps pain or cramping compared to 2 patients (3%) in the onlay group (p = .11). One Popeye deformity was noted in each group (p = .67). No significant differences were found between groups for VAS (p=.41), ASES functional (p = .61), ASES Index (p = .91), SANE (p = .09), VR-12 PCS (p = .77), or VR-12 MCS (p = .09). Rotator cuff tear size within the groups also did not demonstrate statistical significance. ConclusionNo clinical differences or complications were found at minimum two-year follow-up between inlay and onlay arthroscopic biceps tenodesis in patients undergoing rotator cuff repair when controlling for tear size. The clinical relevance suggests either technique is effective and can be based on surgeon preference.

Functional outcomes and survivorship following aseptic revision shoulder arthroplasty

BackgroundRevision shoulder arthroplasty (SA) is a surgical procedure performed to address complications or failures of primary total SA. However, limited evidence exists regarding the functional outcomes and longevity of implants following revision. MethodsA retrospective analysis was conducted on patients who underwent revision SA for failed primary arthroplasty at a single institution between 2009 and 2021 with a minimum of 2-years follow-up. Data was collected from medical records, including type of arthroplasty (anatomic total SA [TSA], reverse total SA [RSA], or hemi-SA [HSA]), demographics and patient-specific information, functional measurements, and implant survival. Patient reported outcomes were obtained during follow-up by phone. ResultsThe mean age at index and revision surgeries was 60.5 ± 12.1 years and 64.8 ± 11.1 years, respectively, and average total follow-up was 5.5 ± 3.5 years. The average time to revision was 4.5 ± 5.2 years (range 0.01–24.5 years). Among 99 revision shoulder arthroplasty procedures, 28 were TSA/HA to TSA/HA, 51 were TSA/HA to RSA, 18 were RSA to RSA, and 2 were RSA to HA. Revision surgery significantly improved functional outcomes in forward elevation (preoperative: 79.8 ± 41.0 vs postoperative: 118.5 ± 38.3; p < 0.001), external rotation (preoperative: 27.8 ± 19.3 vs postoperative: 34.3 ± 16.2; p = 0.028), internal rotation (preoperative: glute vs postoperative: S1; p = 0.002), and forward elevation strength (preoperative: 4+/5 vs postoperative: 5/5; p = 0.002). Postoperative patient reported outcomes included: VAS pain (2.2 ± 2.9), SANE (72.6 ± 21.5), ASES (73.3 ± 20.4), and SST (7.7 ± 2.8) scores. The overall 2-, 5-, and 10-year post-revision implant survival rate was 85.48%, 83.06%, and 79.84%, respectively. Patients who had an initial RSA and were revised to RSA were at higher risk of implant failure and subsequent re-revision (RSA to RSA: 1.5 ± 2.5 years vs. TSA/HA to RSA: 2.5 ± 2.1 years vs. TSA/HA to TSA/HA: 4.0 ± 3.5 years; p = 0.0046) ConclusionRevision shoulder arthroplasty improved patient outcomes post-index arthroplasty failure. Revisions were more likely to be successful when revising from TSA/HA to RSA. Level of evidenceLevel III – retrospective comparative study.

Distal clavicle autograft for large glenoid defects during revision reverse total shoulder arthroplasty

IntroductionRevision reverse total shoulder arthroplasty (rTSA) can be complicated by significant glenoid bone loss and require augmented baseplates or structural bone grafts to fill the defect while optimizing glenosphere lateralization. Distal clavicle autografting is a newly described type of structural graft that has shown promising outcomes in revision reverse rTSA to address severe glenoid bone loss. Additionally, distal clavicle autografts are an option that is proposed to be more cost effective and have low morbidity in addressing glenoid bone defects. The technique for distal clavicle autografting during revision rTSA and the outcomes of a series of cases are contained within this report. Materials and MethodsA retrospective chart review was conducted for 9 patients who underwent revision rTSA with a distal clavicle autograft for glenoid bone loss between January 2013 to January 2022. The primary outcome was component survivorship at two years postoperatively. Patient charts were reviewed for clinical and radiographic information, and any complications were recorded. Postoperative radiographs were assessed for evidence of component loosening or failure. Distal clavicle and glenoid defect dimensions were measured using preoperative CT scans and compared. Results9 patients were identified who underwent revision rTSA with distal clavicle autograft to address glenoid bone loss. All patients had clinical and radiographic data available two years postoperatively. There was significant improvement in active forward flexion and abduction, and no-significant change in external rotation compared to preoperative measurements. Patient-reported QuickDASH score improved significantly with non-significant improvements in VAS function, SANE, and ASES scores. 8 of 9 (88.9%) of patients had stable prostheses with no evidence of loosening or failure at two years. One patient experienced component failure and graft osteolysis requiring conversion to hemiarthroplasty. No other complications were noted. Dimensions of the distal clavicle are similar to the dimensions of contained glenoid vault defects and glenoid defects with minimal loss of containment. ConclusionUsing a distal clavicle autograft during revision rTSA is an effective technique that can address severe glenoid bone loss. This technique has excellent radiographic outcomes at short-term follow-up and is a fortuitous autograft option in revision rTSA due to its location, dimensions, and low cost.

Role of placental membrane in ACL graft healing – A series of 18 patients

IntroductionACL injuries are common and the standard treatment remains to be ACL reconstruction. Controversy still remains around graft ligamentisation and various methods have been experimented to augment this process. In this series we discuss the outcome of using dehydrated umbilical cord derived membrane in ACL reconstruction. Material and methodA prospective Level IV analysis of outcome in 30 consecutive patients of complete isolated ACL tear presenting to us between May 2022 to September 2022 was done. There was no age or sex restriction. Revision cases were excluded from this series. ACL reconstruction was done using standard all inside technique using the ipsilateral semitendinosus graft which was wrapped with dehydrated umbilical cord derived membrane (5*3 cm2) after soaking in normal saline (Cord Thick - Life Cell; LifeCell international private limited, Chennai, Tamil Nadu, India) and secured with Monocryl 3-0 sutures in a continuous manner. Results18 patients completed the one year follow up and were analysed for final results. Eleven of the patients followed up were females and seven males, with an average age of 30.3 years.The average VAS score at 6 weeks was 2.2. The mean KOOS score at the follow up visits were 72.3, 82.3, 90.7, 95.8. The mean SANE score reported at 6 weeks, 3 months, 6 months and 1 year were 68.8, 80, 87.5, 95.1.The follow up MRI's confirmed good ligamentisation of the graft even as early as 6 weeks with minimal fluid in the tunnel. ConclusionThe use of dehydrated umbilical cord derived membrane augmentation to potentiate graft integration in ACL reconstruction seems promising and helps improve patient outcomes.

Current Concepts in Management of Acromioclavicular Joint Injury.

Background: The management of acromioclavicular joint injuries requires a thorough understanding of the anatomy and biomechanics of the joint, as well as knowledge of the pertinent physical exam findings and classification to determine an appropriate treatment approach, whether operative or nonoperative. In this article, we present a narrative review of the current state of understanding surrounding these issues. Although there are a large number of options for operative intervention, we additionally present our experience with anatomic coracoclavicular ligament reconstruction (ACCR) with imbrication of the deltoid fascia. Methods: A retrospective review of prospectively collected data on a total of 45 patients who had undergone ACCR between 2003 and 2016 were collected. Results: We found that improvements were seen in American Shoulder and Elbow Surgeons Score (ASES) (53 ± 19 to 81 ± 23), Simple Shoulder Test (SST) (6 ± 3 to 12 ± 13), Constant-Murley (CM) (60 ± 18 to 92 ± 8), and Rowe (67 ± 14 to 89 ± 11) and the mean post-operative SANE score was 86 ± 17. Conclusions: ACCR has the advantage of addressing both horizontal and vertical stability with good outcomes.

The role of body mass index in survivorship and clinical outcomes in total shoulder arthroplasty

Increased body mass index (BMI) is a potential risk factor for poorer outcomes and complications. However, the influence of BMI on the long-term outcomes of anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) remains to be fully elucidated. Institutional records were queried to identify patients who underwent primary total shoulder arthroplasty (TSA) between 2009 and 2020 with a minimum of 2 years of clinical follow-up. Retrospective review was performed to collect demographic characteristics; comorbidity status; and range-of-motion and strength measurements in forward elevation, external rotation, and internal rotation. Patients were contacted by telephone to provide patient-reported outcomes (PROs). Patients were stratified into 3 cohorts by BMI: underweight or normal weight (U/NW, BMI ≤25 kg/m2), overweight (OW, BMI >25 to ≤30 kg/m2), and obese (BMI >30 kg/m2). Among 466 TSA patients, 245 underwent aTSA whereas 221 underwent rTSA. In the aTSA cohort, 40 patients were classified as U/NW; 72, as OW; and 133, as obese. Comparatively, the rTSA cohort was composed of 33 U/NW, 79 OW, and 209 obese patients. Patients in the aTSA and rTSA cohorts had an average follow-up period of 5.8±3.2 years and 4.5±2.3 years, respectively. No differences in age at surgery were found in the aTSA group (U/NW vs. obese, 65.2±7.9 years vs. 61.9±8.9 years; P=.133); however, in the rTSA cohort, BMI was found to be inversely related to age at surgery (U/NW vs. obese, 72.4±8.8 years vs. 65.7±8.3 years; P<.001). Across all BMI cohorts, patients saw great improvements in range of motion and strength. Postoperative PROs after TSA did not vary by BMI in terms of Single Assessment Numeric Evaluation, Simple Shoulder Test, visual analog scale pain, and American Shoulder and Elbow Surgeons scores. There was no significant difference in survival rates at 10-year follow-up in the aTSA cohort (U/NW vs. obese, 95.8% vs. 93.2%; P=.753) or rTSA cohort (U/NW vs. obese, 94.7% vs. 94.5%; P=.791). With dramatic improvements in range of motion, minimal differences in PROs, and high rates of implant survival, TSA is a safe and effective treatment option for all patients, including overweight and obese patients.

Bilateral reverse shoulder arthroplasty versus bilateral anatomic shoulder arthroplasty: a meta-analysis and systematic review.

As the population is aging and indications are expanding, shoulder arthroplasty is becoming more frequent, especially bilateral staged replacement. However, surgeons are hesitant to use bilateral reverse prostheses due to potential limitations on activities of daily living. This meta-analysis was conducted to compare bilateral anatomic to bilateral reverse shoulder implants. PubMed, Cochrane, and Google Scholar (pages 1-20) were searched until April 2023. The clinical outcomes consisted of postoperative functional scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], Physical Component Score [PCS], Mental Component Score, and Simple Shoulder Test), pain, and range of motion (external rotation and forward elevation). Three studies were included in this meta-analysis. Bilateral anatomic implants had better postoperative functional outcomes and range of motion, but no significant difference was seen in postoperative pain when compared to the reverse prosthesis. Better ASES score, SANE score, and PCS as well as better external rotation and forward elevation were seen in the bilateral anatomic shoulder replacement group, but no significant difference in pain levels was seen between the two groups. The results may be explained by the lower baseline seen in the reverse prosthesis group, which may be due to an older population and different indications. Nevertheless, more randomized controlled studies are needed to confirm these findings. Level of evidence: III.

The COVID-19 Pandemic Shut Down Did Not Adversely Affect Outcomes of Arthroscopic Rotator Cuff Repair

Introduction We investigated whether patients who received an arthroscopic rotator cuff repair (RCR) in January-March 2020 had a difference in outcomes compared to patients who received it the previous year. Materials and Methods Institutional records were queried to identify patients who underwent an arthroscopic RCR between 1/1/19 to 3/17/19 and 1/1/20 to 3/17/20. The 2020 patients were contacted by phone in October 2022 for follow-up. Patients were divided into cohorts based on year of surgery. Demographic information, range of motion (ROM), and physical therapy were analyzed using inferential statistics. Results This study identified 50 and 51 patients in 2020 and 2019, who had a minimum of 1 year follow-up. Rotator cuff repairs done in 2019 had improvements in forward elevation (FE) (135º to 161º; p&lt;0.01) and internal rotation (IR) (L4 to L1; p-value&lt;0.01) whereas those done in 2020 did not improve their forward elevation (146º to 151º; p=0.42) or internal rotation (L3 to L2; p=0.29). Patients in 2019 completed more physical therapy sessions (2019: 25.0; 2020: 16.7; p&lt;0.01). Patients in 2020 also experienced a significant delay from date of surgery to date of first physical therapy session (2019: 28.5 ± 11.9 days; 2020: 35.0 ± 16.5 days; p-value=0.03). Of the 2020 patients, 8% (4/50) patients did not initiate physical therapy after RCR, 16% (8/50) reported a delay in physical therapy while 44% (22/50) reported that the COVID-19 pandemic affected their recovery following RCR. At final follow up, patients reported a SANE score of 78.2 ± 12.1 on the affected shoulder, 91.3 ± 10.4 on the unaffected shoulder, a mean VAS pain score of 2.3 ± 1.8. Discussion Patients who underwent arthroscopic RCR in early 2020 had a longer delay to starting PT, did less PT overall, but still had comparable range of motion and strength at final follow-up.

Time required to achieve clinically significant outcomes after arthroscopic superior capsular reconstruction

AbstractPurposeTo investigate the time‐dependent nature of clinically significant outcomes, including the minimal clinically important difference (MCID), substantial clinical benefit, and Patient Acceptable Symptomatic State (PASS) after arthroscopic superior capsular reconstruction, and the factors contributing to the achievement of early clinically significant outcomes.MethodsPatients who underwent ASCR between March 2015 and September 2020 with complete preoperative and postoperative 6‐month, 1‐year, and 2‐year patient‐reported outcome measures (PROMs) were retrospectively analysed. Threshold values for MCID, substantial clinical benefit, and PASS were obtained from the previous literature for the PROMs. The time required to achieve clinically significant outcomes was calculated using Kaplan–Meier analysis. Multivariate Cox regression was performed to evaluate the variables predictive of an earlier or delayed achievement of MCID.ResultsFifty‐nine patients with a mean age of 64.5 ± 8.7 years old were included. The time of mean achievement of MCID, substantial clinical benefit, and PASS for VAS was 11.2 ± 0.9, 16.3 ± 1.1, and 16.6 ± 0.9 months, respectively. The time of mean achievement of MCID, substantial clinical benefit, and PASS for ASES was 13.2 ± 1.0, 16.8 ± 1.0, and 18.3 ± 0.9 months, respectively. The time of mean achievement of MCID, substantial clinical benefit, and PASS for the Constant score was 11.6 ± 0.9, 15.1 ± 1.0, and 14.7 ± 0.9 months, respectively. The time of mean achievement of MCID, substantial clinical benefit, and PASS for SANE was 14.4 ± 1.0, 16.1 ± 1.0, and 15.5 ± 0.8 months, respectively. Patients with a higher preoperative VAS score achieved an earlier MCID for VAS (P = 0.014). However, patients with a higher preoperative ASES and SANE scores achieved delayed MCID for ASES and SANE (P = 0.026, and P &lt; 0.001, respectively).ConclusionMost patients achieved MCIDs around 1 year after arthroscopic superior capsular reconstruction. A higher preoperative VAS score favours faster MCID achievement, while higher preoperative ASES and SANE scores contribute to delayed MCID achievement.Study designCohort studyLevel of evidenceLevel IV.

Remplissage reduced sense of apprehension and increased the rate of return to sports at preinjury level of elite overhead athletes with on-track anterior shoulder instability.

The purpose of this study was to compare the results of arthroscopic isolated Bankart repair (B) with Bankart repair plus Remplissage (B + R) procedure in contact overhead athletes with on-track anterior shoulder instability. A total of 64 athletes playing basketball, volleyball and handball in elite professional level who underwent arthroscopic isolated Bankart repair (34 patients) or Bankart repair plus Remplissage procedure (30 patients) with the diagnosis of recurrent anterior shoulder instability between 2017 and 2020, were retrospectively reviewed. Radiologically all patients had on-track Hill-Sachs defects and minimal or subcritical glenoid bone loss (< 13.5%). Patients were evaluated using pre- and postoperative pVAS, SANE, ASES, ROWE, WOSI scores and postoperative active ROM assessment. Patients were also asked for the frequency of any subjective apprehension and satisfaction with the surgery in four grades. The mean ages of the groups B and B + R were 26.8 and 26years (SD = 3.22), respectively; the mean follow-up times were 37.8 and 36.2months (SD = 11.19). Compared with the preoperative status, there was a statistically significant improvement of all 5 postoperative outcome scores in both groups (P < 0.001). However, significant difference between the improvement of the groups were only found for the SANE (B: 22.3 ± 4.1, B + R: 26.3 ± 4.3; P = 0.0004), ASES (B: 26.1 ± 2.6, B + R: 30.2 ± 3.6; P < 0.001) and ROWE (B: 42 ± 3.7, B + R: 47.7 ± 2.8; P < 0.001) scores in favor of the group B + R. The loss of internal and external rotation of the adducted arm in group B + R was found to be approximately 5 degrees compared to the group B (P < 0.001). More than 80% of group B + R showed no apprehension in sports activities and almost completely returned to pre-injury athletic level, depicting statistically significant improvement compared to group B athletes (P = 0.002 and 0.036, respectively). 3 patients developed re-dislocation after isolated Bankart repair, whereas no re-dislocation occurred in the B + R group. Adding Remplissage procedure to the Bankart repair provided an advantage in terms of both return to sport at preinjury level and the frequency of apprehension sensation during sports activity. III.
