We evaluated anatomic total shoulders undergoing early revision (less than two years) in the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) and the Kaiser Permanente Shoulder Arthroplasty Registry (KPSAR).
A cross-sectional comparison of both registries was performed between the years of 2009 and 2012. Only patients who underwent anatomic total shoulder arthroplasty for a primary diagnosis of osteoarthritis were included. Aggregate-level data of patients undergoing early revisions done within two years of index arthroplasty were evaluated, and descriptive analysis was conducted.
During the study period, 4614 patients were identified in the AOANJRR compared to 2036 in the KPSAR. Rotator cuff pathology, component loosening, and prosthetic instability were among the most common reasons for revision in both registries. A higher rate of revision in the AOANJRR was found to be secondary to the failure of one specific prosthesis, which has since been discontinued.
Comparing reasons for early revision in total shoulder arthroplasty revealed several similarities between the AOANJRR and KPSAR. Differences were also noted, and this study served to highlight the importance prosthesis selection can play in determining outcomes. Cooperation among registries may allow for earlier identification of risk factors for failure in shoulder arthroplasty.
我们在澳大利亚骨科协会国家关节置换登记处（AOANJRR）和凯撒医疗永久肩部置换登记处（KPSAR）评估了接受早期翻修（不到两年）的解剖型全肩关节置换术。
在2009年至2012年期间对两个登记处进行了横断面比较。仅纳入因原发性骨关节炎的初步诊断而接受解剖型全肩关节置换术的患者。评估了在初次置换术两年内进行早期翻修的患者的汇总数据，并进行了描述性分析。
在研究期间，AOANJRR中识别出4614例患者，而KPSAR中为2036例。肩袖病变、假体松动和假体不稳定是两个登记处最常见的翻修原因。发现AOANJRR中较高的翻修率继发于一种特定假体的失败，该假体此后已停产。
比较全肩关节置换术早期翻修的原因发现，AOANJRR和KPSAR之间有几个相似之处。也注意到了差异，这项研究有助于突出假体选择在决定结果中可能发挥的重要作用。登记处之间的合作可能有助于更早地识别肩关节置换术失败的风险因素。
