Follow-up examinations of 45 patients who received shoulder arthroplasty for osteoarthritis following shoulder instability were conducted after 44 months. The goal of this study was to describe the clinical findings associated with advanced glenohumeral arthritis due to shoulder instability and instability repairs and to present the clinical results and complications of treating this with shoulder arthroplasty. The weighted average Constant score increased significantly from 49.4 to 81.3 points. There was no significant difference in the type of arthroplasty with 35 cases of total shoulder replacements and ten cases of hemiarthoplasty. The rate of complications was 40% (18/45 patients) with 20% (9/45 patients) requiring an operative revision. Patients with arthritis after instability repair showed great improvement in all qualities of the Constant score. Nonetheless, further analyses are required to determine why such a relatively young group of patients showed high complication rates.
对 45 例因肩关节不稳定而行肩关节置换术治疗骨关节炎的患者进行了 44 个月的随访。本研究的目的是描述因肩关节不稳定和不稳定修复而导致的进展性全肩关节关节炎的临床发现，并介绍用肩关节置换术治疗这种疾病的临床结果和并发症。加权平均Constant 评分从 49.4 分显著增加到 81.3 分。全肩关节置换 35 例，部分肩关节置换 10 例，两种关节置换术类型无显著差异。并发症发生率为 40%（45 例患者中有 18 例），需要手术翻修的患者占 20%（45 例患者中有 9 例）。不稳定修复后关节炎患者的 Constant 评分各项质量均有显著改善。尽管如此，仍需要进一步分析为什么这么年轻的一组患者会出现较高的并发症发生率。
