The purpose of the study was to establish radiologic and clinical occurrence of glenohumeral arthrosis after arthroscopic Bankart repair.
Between January 1994 and December 1998, an arthroscopic Bankart repair was performed in 187 patients at our institution. We were able to assess clinical and radiologic glenohumeral arthrosis in 72 of the 101 patients who met the inclusion criteria (74 shoulders) (71%) after a 13-year follow-up. An additional 9 patients were interviewed by telephone. Radiologic arthrosis was evaluated with the Samilson-Prieto classification and clinical arthrosis with an arthrosis-specific quality-of-life questionnaire (Western Ontario Osteoarthritis of the Shoulder test). In addition, functional impairment was assessed with the Constant score and subjective satisfaction with a questionnaire.
Radiologic arthrosis was diagnosed in 50 of 74 shoulders (68%), with 40 (80%) of them classified as mild. The mean score on the Western Ontario Osteoarthritis of the Shoulder questionnaire was 280 points (85% of the best possible score), which is considered relatively good. The mean Constant score was 78 points, and 75% of the patients were extremely satisfied or satisfied with the final results of operative treatment.
The radiologic evaluation and self-assessment of the patients imply that the incidence of glenohumeral arthrosis after arthroscopic Bankart repair is quite common but the symptoms are generally mild and comparable to nonoperative treatment.
Arthrosis rarely causes more than minor subjective symptoms or a minor objectively perceived disadvantage during 13 years' follow-up.
本研究的目的是确定关节镜下 Bankart 修复术后盂肱关节炎的放射学和临床发生情况。
1994 年 1 月至 1998 年 12 月，在我们的机构中对 187 例患者进行了关节镜下 Bankart 修复。在 13 年的随访后，我们能够评估符合纳入标准的 101 例患者中的 72 例（74 肩）（71%）的临床和放射学盂肱关节炎。另外，通过电话采访了 9 例患者。采用 Samilson-Prieto 分类评估放射学关节炎，采用关节炎特异性生活质量问卷（Western Ontario Osteoarthritis of the Shoulder test）评估临床关节炎。此外，使用 Constant 评分评估功能障碍，使用问卷评估主观满意度。
74 肩中有 50 肩（68%）诊断为放射学关节炎，其中 40 肩（80%）为轻度。Western Ontario Osteoarthritis of the Shoulder 问卷的平均得分为 280 分（最佳得分的 85%），这被认为是相对较好的。Constant 评分的平均得分为 78 分，75%的患者对手术治疗的最终结果非常满意或满意。
放射学评估和患者的自我评估表明，关节镜下 Bankart 修复术后盂肱关节炎的发生率相当常见，但症状通常较轻，与非手术治疗相当。
在 13 年的随访中，关节炎很少导致明显的主观症状或轻微的客观感知缺陷。
