To evaluate and compare the functional outcomes after arthroscopic repair of bursal-sided versus articular-sided partial-thickness rotator cuff tears.
We conducted a retrospective analysis of patients who had undergone arthroscopic tear completion and subsequent repair of symptomatic partial-thickness rotator cuff tears in a single institution from 2010 to 2015. Range of motion (ROM) (forward flexion and abduction), the pain score as measured on the Numeric Pain Rating Scale, and outcome scores (Constant-Murley score, University of California, Los Angeles shoulder score, and Oxford Shoulder Score) were calculated preoperatively and at 1 year and 2 years postoperatively. The delta difference was calculated for each outcome parameter at the respective follow-up points as the difference from the preoperative baseline score.
A total of 104 patients were included. All tears involved the supraspinatus tendon and did not exceed 2 cm. Of the patients, 65 had an articular-sided tear (AST) whereas 39 had a bursal-sided tear (BST). The mean age of the patients was 53.4 years in the AST group and 55.8 years in the BST group. The AST and BST groups did not differ preoperatively in terms of age, sex, and the measured outcome parameters. Postoperatively, the patients in both groups achieved statistically significant improvement in pain relief and functional outcomes at 2 years. No statistically significant difference was observed between the 2 groups in terms of the delta-difference outcomes in ROM in forward flexion (P = .781) or abduction (P = .348), pain score (P = .187), Constant-Murley score (P = .186), University of California, Los Angeles shoulder score (P = .911), and Oxford Shoulder Score (P = .186) at 2 years.
Partial-thickness rotator cuff tears treated with arthroscopic tear completion and subsequent repair achieved good outcomes in terms of ROM, functional outcomes, and pain relief at 2 years. There was no difference in outcomes regardless of whether the location of the tear was articular sided or bursal sided.
Level III, retrospective comparative study.
评估和比较关节侧和滑囊侧部分厚度肩袖撕裂关节镜修复后的功能结果。
我们对 2010 年至 2015 年在一家机构接受关节镜撕裂完成和随后治疗症状性部分厚度肩袖撕裂的患者进行了回顾性分析。运动范围（ROM）（前屈和外展）、数字疼痛评分量表测量的疼痛评分以及结果评分（常数-默雷评分、加利福尼亚大学洛杉矶肩部评分和牛津肩部评分）在术前和术后 1 年和 2 年进行计算。在各自的随访点，通过从术前基线评分中减去差异来计算每个结果参数的差值差异。
共纳入 104 例患者。所有撕裂均累及冈上肌腱且不超过 2cm。其中 65 例为关节侧撕裂（AST），39 例为滑囊侧撕裂（BST）。AST 组患者的平均年龄为 53.4 岁，BST 组为 55.8 岁。AST 和 BST 两组在年龄、性别和测量的结果参数方面术前无差异。两组患者术后在 2 年时在疼痛缓解和功能结果方面均取得统计学显著改善。在 ROM 的前屈（P=0.781）或外展（P=0.348）、疼痛评分（P=0.187）、常数-默雷评分（P=0.186）、加利福尼亚大学洛杉矶肩部评分（P=0.911）和牛津肩部评分（P=0.186）方面，两组间的差异无统计学意义。
关节镜完成撕裂和随后修复治疗部分厚度肩袖撕裂在 2 年内获得了良好的 ROM、功能结果和疼痛缓解效果。无论撕裂的位置是关节侧还是滑囊侧，结果都没有差异。
