Background: Despite increasing use of quadriceps tendon (QT) autograft in anterior cruciate ligament (ACL) reconstruction (ACLR), limited data exist regarding its outcomes in high-risk adolescent athletes., Purpose: To (1) report the outcomes after QT ACLR in adolescent athletes and (2) identify patient-related and surgery-related factors that may influence failure rates after QT ACLR., Study Design: Case series; Level of evidence, 4., Methods: All patients aged 14 to 17 years who underwent primary anatomic, transphyseal, single-bundle QT ACLR between 2010 and 2021 with a minimum 2-year follow-up were included for analysis. Demographic and surgical data as well as preoperative International Knee Documentation Committee (IKDC) and Marx activity scores were collected retrospectively. All patients were also contacted to assess postoperative patient-reported outcomes (PROs), including IKDC and Marx activity scores, and return-to-sports (RTS) data. Outcomes of interest included rates of revision ACLR and ipsilateral complications, contralateral ACL tears, difference in pre- and postoperative PROs, and rates of RTS. Patient and surgical characteristics were compared between groups who required revision ACLR versus those who did not., Results: A total of 162 patients met inclusion criteria, of which 89 adolescent athletes (mean age 16.2 ± 1.1 years, 64% female) were included for analysis at mean follow-up of 4.0 years. Postoperative IKDC scores were significantly higher than preoperative scores (88.5 vs 37.5; P  < .001), whereas Marx activity scores decreased postoperatively (14.3 vs 12.2; P  = .011). Successful RTS occurred in 80% of patients at a mean time of 9.7 ± 6.9 months, and 85% of these patients returned to the same or higher level of sports. The most common reasons for failure to RTS included lack of time (n = 7, 70%) and fearing reinjury in the operative knee (n = 5, 50%). The overall revision ACLR rate was 10% (n = 9), and contralateral ACL tears occurred in 14% (n = 12) of patients. The overall ipsilateral knee reoperation rate was 22.5% (n = 20). No statistically significant differences in patient or surgical characteristics were observed between patients who underwent revision ACLR and those who did not., Conclusion: At a minimum 2-year follow-up after QT ACLR, adolescent athletes experienced significantly improved postoperative IKDC scores, high rates of RTS, and low rates of graft failure, despite a relatively high ipsilateral reoperation rate. Surgeons may utilize this information when identifying the optimal graft choice for adolescent athletes who have sustained an ACL injury and wish to return to high level of sporting activities., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: L.M. has received a grant from Arthrex; education payments from Mid-Atlantic Surgical Systems and Smith+Nephew; and hospitality payments from Stryker.

Background: Diminished postoperative knee extension strength may occur after anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autograft. Factors influencing the restoration of knee extensor strength after ACLR with QT autograft remain undefined., Purpose: To identify factors that influence knee extensor strength after ACLR with QT autograft., Study Design: Case-control study; Level of evidence, 3., Methods: The authors performed a retrospective review of patients who underwent primary ACLR with QT autograft at a single institution between 2010 and 2021. Patients were included if they completed electromechanical dynamometer testing at least 6 months after surgery. Exclusion criteria consisted of revision ACLR, <6 months of follow-up, concomitant procedure (osteotomy, cartilage restoration), and concomitant ligamentous injury requiring surgery. Knee extension limb symmetry index (LSI) was obtained by comparing the peak torque of the operated and nonoperated extremities. Univariable and multivariable analyses were performed to identify factors associated with knee extension LSI in the patient, injury, rehabilitation, and preoperative patient-reported outcomes score domains., Results: A total of 107 patients (58 male; mean age, 22.8 years) were included. Mean knee extension LSI of the overall cohort was 0.82 ± 0.18 at 7.5 ± 2.0 months; 35 patients (33%) had a value of ≥0.90. Multivariable analysis demonstrated significant negative associations between knee extension LSI and female sex (-0.12; P < .001), increased age at the time of surgery (-0.01; P = .018), and larger QT graft width (-0.049; P = .053)., Conclusion: Factors influencing knee extensor LSI after ACLR with QT autograft in this study population spanned patient and surgical factors, including female sex, older age at the time of surgery, and wider graft harvest. Surgeons should consider the association between these factors and lower postoperative knee extensor LSI to optimize patient outcomes., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding.

Objective: To compare postoperative isometric quadriceps strength indices (QI%) and hamstring strength limb symmetry indices (HI%) between partial thickness quadriceps tendon (pQT), full thickness quadriceps tendon (fQT), and bone-patellar-tendon bone (BPTB) autograft anterior cruciate ligament reconstruction (ACLR)., Methods: Patients with primary ACLR with pQT, fQT, or BPTB autograft with the documentation of quantitative postoperative strength assessments between 2016 and 2021 were included. Isometric Biodex data, including QI% and HI% (calculated as the percentage of involved to uninvolved limb strength) were collected between 5 and 8 months and between 9 and 15 months postoperatively., Results: In total, 124 and 51 patients had 5-8- and 9-15-month follow-up strength data, respectively. No significant difference was detected between groups for sex. However, patients undergoing fQT were found to be older than those undergoing BPTB (24.6±7 vs 20.2±5; ​p = 0.01). There were no significant differences in the number of concomitant meniscus repairs between the groups (pQT vs. fQT vs. BPTB). No significant differences were detected in median (min-max) QI% between pQT, fQT, and BPTB 5-8 months [87 ​% (44%-130 ​%), 84 ​% (44%-110 ​%), 82 ​% (37%-110 ​%) or 9-15 months [89 ​% (50%-110 ​%), 89 ​% (67%-110 ​%), and 90 ​% (74%-140 ​%)] postoperatively. Similarly, no differences were detected in median HI% between the groups 5-8 months or 9-15 months postoperatively., Conclusion: The study was unable to detect differences in the recovery of quadriceps strength between patients undergoing ACLR with pQT, fQT, and BPTB autografts at 5-8 months and 9-15-months postoperatively., Level of Evidence: III., (Copyright © 2023 The Authors.

Background: Multiple-revision anterior cruciate ligament reconstruction (ACLR) presents several technical challenges, often due to residual hardware, tunnel widening, malposition, or staged surgeries., Purpose: To compare failure and complication rates between the over-the-top (OTT) and transportal drilling (TD) techniques in patients undergoing surgery for failed revision ACLR., Study Design: Cohort study; Level of evidence, 3., Methods: The medical records of patients with at least 2 revision ACLRs using either the OTT or TD technique were reviewed retrospectively. Data on patient demographics, graft characteristics, number of revisions, concomitant procedures, complications, and failures were collected. Between-group comparisons of continuous and categorical variables were conducted with the independent-samples t test and the Fisher exact or chi-square test, respectively., Results: A total of 101 patients undergoing multiple-revision ACLR with OTT (n = 37, 37%) and TD (n = 64, 63%) techniques were included for analysis. The mean follow-up time was 60 months (range, 12-196 months). There were no significant differences in age, sex, body mass index, laterality, or follow-up length between groups ( P > .05). Allograft was the graft used most frequently (n = 64; 67.3%) with no significant differences between groups in graft diameter ( P > .05). There were no statistically significant differences between groups regarding rate of concurrent medial and lateral meniscus, cartilage, or lateral extra-articular procedures ( P > .05). There was also no significant66 between-group difference in complication rate (OTT: n = 2 [5.4%]; TD: n = 8 [13%]) or graft failure rate (OTT: n = 4 [11%]; TD: n = 14 [22%]) ( P > .05 for both)., Conclusion: The results of this study showed notably high failure and complication rates in challenging multiple-revision ACLR. Complication and failure rates were similar between techniques, demonstrating that the OTT technique is a valuable alternative that can be used in a revision ACLR, particularly as a single-stage approach when the single-stage TD technique is not possible., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: E.A.O. was awarded a grant by ESSKA-University of Pittsburgh Sports Medicine Clinical and Research Fellowship, and The Scientific and Technological Research Council of Turkey (TUBITAK) outside the submitted work.

Background: Pectoralis major (PM) tears have been shown to occur most frequently at the tendinous humeral insertion. However, no substantial updates on tear location have been published in 20 years or are based on relatively small sample sizes. The primary purpose of this study was to evaluate PM tear location based on magnetic resonance imaging (MRI). A secondary purpose was to evaluate agreement between MRI and intraoperative assessments of tear characteristics. We hypothesized that PM tears at the myotendinous junction (MTJ) occur at a higher rate than previously reported and that intraoperative and MRI assessments would demonstrate agreement in at least 80% of cases., Materials and Methods: An observational study of consecutive patients evaluated for a PM tear at a single institution between 2010 and 2022 was conducted. Patient demographics as well as MRI and intraoperative assessments of tear location, extent of tear, and muscle head involvement were collected from the electronic medical record. Agreement was calculated by comparing radiographic and intraoperative assessments per variable and reported as percentages. Data and statistical analysis were performed with SPSS software with a significance level set to P  < .05., Results: A total of 102 patients were included for analysis. Mean age was 35.8 ± 10.5 years and mean body mass index was 29.4 ± 4.8 kg/m 2 . 60.4% of the study population had tears of the MTJ, 34.9% of the tendinous humeral insertion, and 4.7% within the muscle belly, as determined intraoperatively. Complete tears had significantly higher agreement between MRI and intraoperative assessments relative to partial tears (83.9% and 62.5%, respectively; P ≤ .01)., Discussion: The majority of PM tears occurred at the MTJ. Preoperative MRI and intraoperative assessments agreed in 80% of cases, a value that was significantly higher for complete over partial tears. These findings demonstrate that tears of the MTJ are increasingly more common and support the use of MRI in preoperative planning for complete PM tears., (© 2023 The Author(s).)

Background: Multiple rehabilitation protocols after shoulder surgery have been proposed. The coronavirus pandemic adds an extra layer of complexity to postoperative rehabilitation after shoulder surgery., Hypothesis: The combined use of a home-based rehabilitation system, the Shoulder Strengthening and Stabilization System (SSS), and telehealth visits will lead to acceptable patient self-reported outcomes and satisfaction after shoulder surgery., Study Design: Prospective observational cohort., Level of Evidence: Level 4., Methods: A total of 132 patients were prescribed SSS after shoulder surgery. A virtual clinical specialist monitored patients through telehealth visits as prescribed by the treating physician. Data were collected prospectively during each telehealth visit. Patients completed an exit survey during their last telehealth visit., Results: The use of SSS with telehealth revealed a positive impact on postoperative shoulder rehabilitation (96%), pain (71%), and stiffness (92%) as reported by patients. Both pain scores and pain medication use decreased from the 1st to 8th postoperative telehealth session ( P < 0.01). Nearly all (93%) patients recommended SSS after shoulder surgery upon completing the SSS protocol., Conclusion: Postoperative management of shoulder surgery with SSS combined with telehealth results in a reduction in patient pain levels in the early postoperative period. Patients reported high levels of improvement with SSS in shoulder rehabilitation, pain, and stiffness. The overwhelming majority (93%) of patients recommended SSS for postoperative shoulder rehabilitation and SSS yielded high patient satisfaction scores. Elucidating the impact of SSS on clinical outcomes and function in comparison with traditional rehabilitation protocols is warranted., Clinical Relevance: SSS in combination with telehealth was tolerated well by patients and may represent an alternative or adjunct to traditional rehabilitation protocols.

Background: Leg length and hip offset are important principles in total hip arthroplasty (THA). Patients may endorse leg length differences (LLD) postoperatively that may be anatomical or functional. The objective of this study was to determine the normal radiographic variation in leg length and hip offset in a preosteoarthritic population without a THA., Methods: A retrospective study was completed using data from the Osteoarthritis Initiative, a prospective longitudinal study. Patients at risk of developing or with early osteoarthritis without inflammatory arthritis or prior THA were included. Measurements were made from full limb length anterior-posterior (AP) radiographs. Multiple linear regression models were employed to predict side-to-side differences in LLD, Δ femoral offset (FO), Δ abductor muscle length (AML), Δ abductor lever arm, and Δ AP pelvic offset., Results: The mean radiographic LLD was 4.6 mm, with 12 mm within 1 standard deviation. No significant differences were detected between LLD and sex, age, body mass index, or height. The median radiographic differences in FO, AML, abductor lever arm, and AP pelvic offset were 3.2 mm, 4.8 mm, 3.6 mm, and 3.3 mm, respectively. Height was predictive of Δ FO, while both height and age were predictive of Δ AML., Conclusions: Radiographic leg length variations in a population without symptomatic or radiographic osteoarthritis exist. FO and AML are dependent on patient characteristics. Preoperative radiographic LLD is not predicted by age, gender, body mass index, or height. It should be stressed that anatomic reconstruction is one of the many goals of arthroplasty and can stand in conflict with the priority and primary goals of stability and fixation, which should be prioritized., (© 2023 The Authors.)

Purpose: To evaluate factors associated with postoperative anterior shoulder pain following arthroscopic suprapectoral biceps tenodesis (ABT) and to determine the clinical impact of postoperative anterior shoulder pain., Methods: A retrospective study of patients that underwent ABT between 2016 and 2020 was conducted. Groups were categorized by the presence (ASP+) or absence (ASP-) of postoperative anterior shoulder pain. Patient-reported outcomes (American Shoulder and Elbow score [ASES], visual analog scale [VAS] for pain, subjective shoulder value [SSV]), strength, range of motion, and complication rates were analyzed. Differences between continuous and categorical variables were tested with two-sample t -tests and chi-squared or Fisher's exact tests, respectively. Variables collected at different postoperative timepoints were analyzed using mixed models with post hoc comparisons when significant interactions were detected., Results: A total of 461 (47 ASP+, 414 ASP-) patients were included. A statistically significant lower mean age was observed in the ASP+ group ( P < .001). A statistically significant higher prevalence of major depressive disorder (MDD) ( P  = .03) or any anxiety disorder ( P  = .002) was observed in the ASP+ group. Prescription medication with psychotropic medications ( P  = .01) was significantly more prevalent in the ASP+ group. No significant differences were observed in the proportion of individuals reaching the minimal clinical important difference (MCID) for ASES, VAS, or SSV between groups., Conclusions: A pre-existing diagnosis of major depressive disorder or any anxiety disorder, as well as the use of psychotropic medications was associated with postoperative anterior shoulder pain following ABT. Other factors associated with anterior shoulder pain included younger age, participation in physical therapy before surgery, and lower rate of concomitant rotator cuff repair or subacromial decompression. Although the proportion of individuals reaching MCID did not differ between groups, the presence of anterior shoulder pain after ABT resulted in prolonged recovery, inferior PROs, and a higher incidence of repeat surgical procedures. The decision to perform ABT in patients diagnosed with MDD or anxiety should be carefully considered, given the correlation to postoperative anterior shoulder pain and inferior outcomes., Level of Evidence: Level III, retrospective case-control study., (© 2023 The Authors.)
