We present a case of a surgically treated latissimus dorsi (LD) and teres major (TM) tear with a one-year outcome. The postoperative course was complicated by wound dehiscence requiring operative intervention and neuropraxia of the posterior cutaneous nerve of the arm. The report highlights previously unreported surgical risks associated with repair of LD/TM tendons.

Purpose/UNASSIGNED:To evaluate the outcomes of arthroscopic Bankart repair with remplissage (ABRR) compared with the arthroscopic Latarjet (AL) procedure for anterior shoulder instability in patients with a labral tear and a concomitant engaging Hill-Sachs lesion. Methods/UNASSIGNED:A retrospective review of patients who underwent either ABRR or the AL procedure for a diagnosis of anterior shoulder instability with a concomitant engaging Hill-Sachs lesion between 2011 and 2019 was performed. Recurrent instability, the visual analog scale score, the Subjective Shoulder Value, the Western Ontario Shoulder Instability score, patient satisfaction, willingness to undergo surgery again, and return to work or sport were evaluated. Results/UNASSIGNED: = .39). Conclusions/UNASSIGNED:In patients with anterior shoulder instability and a concomitant Hill-Sachs lesion, both ABRR and the AL procedure were shown to be reliable treatments, with a low rate of recurrent instability and excellent patient-reported outcomes in appropriately selected patients. However, our study could not determine whether there was critical glenoid bone loss in patients undergoing ABRR, and surgeons should still exercise caution in performing ABRR in patients with high-grade glenoid bone loss or in those with failed prior stabilizations. Level of Evidence/UNASSIGNED:Level III, retrospective cohort study.

BACKGROUND/UNASSIGNED:Multiple surgical options exist for the treatment of patellar instability; however, the most common procedures involve either a reconstruction of the medial patellofemoral ligament (MPFL) or a repair/plication of the MPFL and medial soft tissues. PURPOSE/UNASSIGNED:To perform a network meta-analysis of the randomized controlled trials (RCTs) in the literature to compare MPFL reconstruction, MPFL repair, and nonoperative management for patellar instability. STUDY DESIGN/UNASSIGNED:Systematic review and network meta-analysis; Level of evidence, 1. METHODS/UNASSIGNED:scores. RESULTS/UNASSIGNED:score for all outcomes in those with first-time dislocation. CONCLUSION/UNASSIGNED:The current study demonstrated that MPFL reconstruction results in the lowest rate of recurrent patellar instability and best functional outcomes as measured using the Kujala score.

BACKGROUND:Patient-reported allergies (PRAs) are often stigmatized as a potential nonmodifiable risk factor for increased pain and worse functional outcomes following surgery. However, there is a dearth of literature directly assessing the impact of PRAs on outcomes in sport surgeries such as medial patellofemoral ligament reconstruction (MPFLR). The purpose of our study was to determine whether PRAs were associated with worse outcomes following MPFLR. METHODS:We conducted a retrospective review of patients who underwent MPFLR at our institution from 2011 to 2019. Patients were included if they had at least 12 months of follow-up. PRAs were obtained from preoperative medical assessments and categorized by drug class. Demographic and perioperative data were obtained from electronic medical records. Postoperative outcomes were measured using a telephone survey and included recurrent instability, Visual analog scale (VAS) for pain, VAS for sports, Kujala score, MPFL-Return to Sport after Injury (MPFL-RSI) score, and overall satisfaction score. Multiple linear regression was used to determine association between PRAs and outcome measures, and p-values less than 0.05 were considered significant. RESULTS:The cohort included 141 MPFLR. Most patients were female (98, 70%) with an average age of 25 years (range 12-56 years). Average follow-up time was 47 months. Forty-seven patients (33%) reported at least one PRA. There were no significant differences in postoperative pain, functional outcomes, satisfaction, or return to sport between patients with or without PRAs (all p > 0.05). Absence of antibiotic PRAs was predictive of higher VAS (p < 0.007), but there were no other differences. There were no significant differences in outcomes between patients without PRAs, PRAs without a concomitant psychiatric disorder, or PRAs with a concomitant psychiatric disorder (all p > 0.05). CONCLUSIONS:In conclusion, PRAs with or without concomitant psychiatric diagnoses are not associated with worse postoperative pain, functional outcomes, or satisfaction following MPFLR with allograft, dispelling common misconceptions that increased number of allergies or psychiatric diagnoses lead to inferior surgical outcomes. Presence of antibiotic allergies was associated with lower VAS postoperative pain score. Future research should investigate the relationship between PRAs and other surgeries in the field of sports medicine.

OBJECTIVES/OBJECTIVE:An isolated medial patellofemoral ligament (MPFL) reconstruction (MPFLR) has been demonstrated to be an effective treatment option in the prevention of patellar instability, but there is growing support for performing a tibial tubercle osteotomy (TTO) in patients with an elevated tibial tubercle-trochlear groove distance. The purpose of this study was to evaluate the impact of adding a TTO to MPFLR on patient-reported outcomes. METHODS:A retrospective review of patients who underwent MPFLR with or without TTO with a minimum of 12-month follow-up was performed. Patients in both groups were matched based on age, gender, and follow-up time. Recurrent instability (including redislocation and subluxation), visual analogue scale (VAS) score, Kujala score, and satisfaction were evaluated. RESULTS:There were 59 patients who underwent MPFLR with concomitant TTO performed at our institution and met our inclusion and exclusion criteria. These patients were then matched to patients undergoing isolated MPFLR based on demographics and follow-up time. The mean age was 25.0 years, 76.3% were female, and the mean follow-up time was 49 months. There was a significant difference in mean tibial tubercle-trochlear groove distance (19.8 ± 3.9 vs. 14.1 ± 2.8) between groups. There was no significant difference in VAS (1.48 ± 2.0 vs. 1.49 ± 2.1, p = 0.972), satisfaction (86.1% ± 24.2% vs. 81.2% ± 27.9, p = 0.311) or revision surgeries (10.2% vs. 10.2%) between groups. CONCLUSION/CONCLUSIONS:Matched patients undergoing MPFLR with TTO compared with isolated MPFLR demonstrate no statistically significant difference in patient-reported outcomes, levels of pain, and satisfaction postoperatively. Furthermore, the addition of a TTO does not increase the risk of further surgery or complications. LEVEL OF EVIDENCE/METHODS:III, retrospective comparative study.

IMPORTANCE/OBJECTIVE:There have been several recent systematic reviews of quadriceps tendon autografts (QT), which have not shown any significant difference in outcomes between QT and hamstring tendon autograft (HS) for ACL reconstruction (ACLR). However, several recent comparative studies have been published comparing QT to HS for ACLR. AIM/OBJECTIVE:The purpose of this study is to perform a systematic review and meta-analysis of the studies comparing QT to HS for ACLR. EVIDENCE REVIEW/METHODS:Two independent reviewers performed the literature search based on the PRISMA guidelines, with a senior author arbitrating discrepancies. Cohort studies comparing QT with HS were included. FINDINGS/RESULTS:There were 15 studies comparing 611 patients with QT to 543 patients with HS, with a mean of 27.4 months follow-up. QT resulted in a significantly lower rate of graft re-rupture (2.5% vs 8.7%, p = 0.01), and donor site morbidity (17.6% vs 26.2%, p = 0.02). There was a significant difference in favour of QT for the positive pivot shift test (Grade I/II: 15.8% vs 23.0%, p = 0.02), but not in the rate of the positive Lachman test (Grade I/II: 18.3% vs 26.7%, p = 0.16). Additionally, there was no difference in the side to side difference in knee stability (1.8 mm vs 2.0 mm, p = 0.48). Functionally, both grafts had similar functional outcomes in terms of the IKDC score (88.0 vs 87.9, p = 0.69), and Lysholm score (89.3 vs 87.6, p = 0.15). CONCLUSIONS AND RELEVANCE/CONCLUSIONS:Our study showed that QT has a lower re-rupture rate than HS in ACLR, with lower donor site morbidity. QT appeared to be slightly better for residual pivot shift, but there was no difference in patient-reported outcomes. LEVEL OF EVIDENCE/METHODS:III.

BACKGROUND/UNASSIGNED:Performing open subpectoral biceps tenodesis in overhead athletes with a superior labrum anterior to posterior (SLAP) tear may affect their ability to return to overhead sports. PURPOSE/UNASSIGNED:To investigate clinical outcomes in overhead athletes undergoing biceps tenodesis for the treatment of symptomatic, isolated SLAP tears involving the biceps-labral complex. STUDY DESIGN/UNASSIGNED:Case series; Level of evidence, 4. METHODS/UNASSIGNED:value of <.05 was considered to be statistically significant. RESULTS/UNASSIGNED:The current study included 44 overhead athletes. The mean age was 34.9 years (range, 16-46 years), 79.5% were male, and the mean follow-up was 49.0 months (range, 18-107 months). Overall, 81.8% of patients returned to play their overhead sport after biceps tenodesis, and 59.1% of patients returned to the same or higher level of play. It took patients, on average, 8.7 months to return to play after biceps tenodesis. The mean SLAP-RSI score was 69.4, and 70.5% of patients passed the SLAP-RSI threshold of 56. The mean ASES score, VAS score, SSV, and satisfaction were 92.0, 0.8, 80.6, and 87.9%, respectively. No patients in our cohort required revision surgery. CONCLUSION/UNASSIGNED:This study found that athletes undergoing biceps tenodesis for the treatment of a symptomatic, isolated SLAP tear had a high rate of return to play, good functional outcomes, and a low rate of revision surgery.

PURPOSE/OBJECTIVE:The purpose of this study was to evaluate the outcomes of patients 5-years post-operatively following arthroscopic superior-labrum anterior-posterior (SLAP) repair, and to evaluate factors associated with satisfaction. METHODS:A retrospective review of patients who underwent SLAP repair with a minimum of 5-year follow-up was performed. Recurrence, Visual Analogue Scale (VAS) score, Subjective Shoulder Value (SSV), American Shoulder & Elbow Surgeons (ASES) score, satisfaction, whether they would undergo the same surgery again, and the rate, level and timing of return to play (RTP) were evaluated. Multi-linear regression models were used to evaluate factors affecting postoperative satisfaction. RESULTS:Overall, 122 patients who underwent SLAP repair were included, with a mean age of 33.4 years. 81% were males, and 58.2% were participating in sport pre-operatively. The mean follow-up was 86.4 ± 14.4 months. At final follow up, the mean satisfaction was 87.7%, and the mean SSV was 82.9. Overall, the rate of RTP was 85.9%, with 64.8% returning at the same level at a mean of 10.5 ± 8 months. Ultimately, 13 (10.7%) patients had a further surgery, including 10 (8.2%) patient that had a biceps tenodesis. VAS during sport (p = 0.025), SSV (p < 0.001), and time to RTP (p = 0.0056), were associated with higher satisfaction. CONCLUSION/CONCLUSIONS:There was a high rate of satisfaction at 5-year follow-up, with excellent patient reported outcomes but with a tenth of patients requiring revision surgeries. Additionally, while there was an overall high rate of RTP, there was only a modest rate of RTP at their pre-injury level and overhead athletes took longer to RTP.

BACKGROUND/UNASSIGNED:As platelet-rich plasma injection for knee osteoarthritis (OA) has increased in popularity, it has become more important to assess its effectiveness and satisfaction with its use in the context of its high cost. The purpose of this study was to determine satisfaction, commercial appeal, and effectiveness of platelet-rich plasma (PRP) for the treatment of knee OA. METHODS/UNASSIGNED:A retrospective review of patients who underwent PRP injection in the knee from 2016 to 2019 was performed. Satisfaction with the PRP injection (out of 100), whether the patient would want to undergo PRP injection again, whether they would recommend the injection and whether they felt that the injection was worth the cost was collected. VAS pain scores were collected and measured out of 100. RESULTS/UNASSIGNED:Overall, 114 patients were included. The mean pre-injection pain score was 70.4, and the mean pain level decreased after injection to 36.8. Patients rated their satisfaction on average at 49.2, 50.9% stated that they would get the PRP injection again, 60.5% would recommend to a friend, and 50.9% felt the injection was worth the cost. Younger age and improved post-injection pain correlated with increasing likelihood of desiring further PRP injection. CONCLUSIONS/UNASSIGNED:Patients on average rated satisfaction slightly below average, indicating net indifference skewing towards dissatisfaction with their injection, and only half indicated that it was worth the cost and that they would receive it again. Younger age and pain relief increased desire for further injection, but efficacy did not correlate with patients saying that the injection was worth the cost.
