PURPOSE/OBJECTIVE:To present the short-term outcomes of arthroscopic in situ biceps tenodesis combined with partial rotator cuff repair in patients with massive irreparable rotator cuff tears (MIRCTs) and minimal arthritis. METHODS:A retrospective review was conducted using prospectively maintained institutional databases to identify patients who had undergone a partial rotator cuff repair with in situ biceps tenodesis between March 2017 and December 2022. Patients were included if they (1) were diagnosed pre- or intraoperatively with MIRCT and (2) had complete preoperative and minimum 1-year postoperative patient-reported outcome measures. RESULTS:Thirty-nine patients met the eligibility criteria and were included for analysis. The mean age of the study participants was 65 ± 7 years (range, 46-76) with 76.9% (n = 30) being male. The average follow-up was 21 ± 12 months (range, 12-58). Patients experienced significant improvement in visual analog scale for pain (VAS), American Shoulder and Elbow Surgeons (ASES) score, and subjective assessment numeric evaluation (SANE) score (P < .001 for all comparisons). The pre- to postoperative improvement was 3.1 ± 2.3 for VAS, 27.5 ± 20.6 for ASES, and 31.3 ± 24.8 for SANE. Postoperatively, the average scores for VAS, ASES, and SANE were 1.3 ± 1.5, 79.5 ± 17.0, and 69.6 ± 20.1, respectively. Twenty-six patients (66.7%) achieved the minimal clinically important difference (MCID) for VAS, 33 patients (84.6%) achieved the MCID for ASES, and 30 patients (76.9%) achieved the MCID for SANE. CONCLUSIONS:Partial rotator cuff repair with in situ biceps tenodesis is an effective treatment for MIRCT, leading to significant improvements in patient-reported outcome and range-of-motion measures compared to preoperative conditions. LEVEL OF EVIDENCE/METHODS:Level IV, retrospective case series.

INTRODUCTION/BACKGROUND:As reverse shoulder arthroplasty (RSA) continues to grow in popularity for the treatment of glenohumeral osteoarthritis (GHOA) with an intact rotator cuff, it becomes increasingly important to identify factors that influence postoperative outcome. Although recent studies have demonstrated excellent postoperative range of motion and patient-reported outcome scores following RSA for GHOA, there continues to be surgeon hesitation to adopt RSA as a viable treatment in the younger patient population due to greater functional demands. In this study, we sought to determine the effect of age on clinical outcomes following RSA for GHOA through a comparison of patients over and under the age of 70. METHODS:A retrospective review of prospectively collected data from an institutional registry was performed. Propensity score matching was utilized to match patients under the age of 70 (U-70) to those over 70 (O-70) in a 1:1 ratio based on sex, body mass index (BMI), preoperative ASES score, preoperative active forward elevation (FE), Walch classification, and American Society of Anesthesiologists comorbidity score. Clinical outcomes obtained preoperatively and at a minimum of 2 years postoperatively consisted of Visual Analog Scale (VAS) for pain, Single Assessment Numeric Evaluation (SANE) score, and American Shoulder and Elbow Surgeons (ASES) score, as well as active (FE), internal rotation, and external rotation. Descriptive statistics and univariate analysis were performed to compare cohorts. RESULTS:After matching, each cohort consisted of 66 patients with similar mean follow-up periods (U-70, 28.1 ± 7.5 months vs. O-70, 27.4 ± 7.5 months; P = .887). Mean age of the U-70 cohort was 66.2 ± 3.3 while the O-70 cohort had a mean age of 75.3 ± 3.8. Both groups demonstrated significant improvement in VAS, SANE, and ASES scores, as well as active range of motion in all planes. The only significant difference between cohorts was greater postoperative FE in younger patients (143 ± 16° vs. 136 ± 15°; P = .017), though the baseline-to-postoperative improvement in FE was similar between cohorts (50 ± 29° vs. 43 ± 29°, P = .174). CONCLUSION/CONCLUSIONS:RSA is a successful surgical treatment for GHOA regardless of age. Aside from greater postoperative FE in younger patients, there were no other differences in clinical outcomes between younger and older patients in this retrospective analysis, which compared patients who were matched by sex, BMI, and Walch classification, among other factors. Based on our results, 70 years of age should not be used as a threshold in preoperative counseling when determining whether a patient with GHOA with an intact rotator cuff is indicated for reverse shoulder arthroplasty.
