Osteoarthritis (OA) in the glenohumeral joint is a concomitant lesion with rotator cuff tear that commonly occurs in older patients. The authors aimed to evaluate the effect of associated OA on the treatment outcome of rotator cuff repair.
A total of three hundred and forty-eight patients who underwent full-thickness arthroscopic rotator cuff repair were retrospectively reviewed, and the data were prospectively collected. The severity of OA was evaluated using the Samilson and Prieto method preoperatively and the Outerbridge classification intraoperatively. The patients were divided into the small-to-medium group and large-to-massive group according to rotator cuff tear size and were evaluated for presence or absence of OA. The postoperative clinical outcomes were assessed using the visual analog scale for pain, simple shoulder test (SST), University of California-Los Angeles, Constant, and American Shoulder and Elbow Surgeons (ASES) scoring systems at baseline and at final follow-up.
Forty-five patients were diagnosed with glenohumeral OA (12.9%). Overall, no significant differences were observed in demographic and baseline data between the two groups according to the presence or absence of OA. The clinical symptoms of both groups significantly improved at the final follow-up. At the final follow-up, no significant differences were found in the VAS for pain, SST, UCLA, Constant, and ASES scores between the two groups. In the large-to-massive tear group, patients with OA had significantly inferior clinical results compared with those without OA.
The clinical outcome scores improved after rotator cuff repair regardless of the presence of concomitant OA. However, glenohumeral OA should be considered as a potential negative prognostic factor in patients with large-to-massive rotator cuff tears.

肩盂肱关节骨关节炎（OA）是肩袖撕裂的伴随病变，常见于老年患者。作者旨在评估伴随 OA 对肩袖修复治疗效果的影响。
回顾性分析了 348 例接受全关节镜肩袖修复的患者，前瞻性收集了数据。术前采用 Samilson 和 Prieto 法、术中采用 Outerbridge 分级评估 OA 的严重程度。根据肩袖撕裂大小将患者分为小-中组和大-巨大组，并评估是否存在 OA。使用视觉模拟评分法（VAS）评估疼痛、简单肩部测试（SST）、加利福尼亚大学洛杉矶分校（UCLA）、Constant 和美国肩肘外科医师协会（ASES）评分系统评估两组患者的术后临床结果，基线和最终随访时。
45 例患者被诊断为盂肱关节 OA（12.9%）。总体而言，根据是否存在 OA，两组在人口统计学和基线数据方面无显著差异。两组的临床症状在最终随访时均显著改善。最终随访时，两组 VAS 疼痛评分、SST、UCLA、Constant 和 ASES 评分无显著差异。在大-巨大撕裂组中，OA 患者的临床结果明显低于无 OA 患者。
无论是否存在伴随的 OA，肩袖修复后临床结果评分均有所改善。然而，在肩袖巨大撕裂的患者中，盂肱 OA 应被视为潜在的负面预后因素。
