The Kaiser Permanente National Total Joint Replacement Registry (TJRR) is a national level database designed as a postmarket surveillance system for elective total hip and knee replacement. As of March 31, 2007, the TJRR recorded 16,945 primary total hip arthroplasties (THA), 2144 revisions (11.2%); and 30,815 total knee arthroplasties (TKA), 1794 revisions (5.5%). Statistically significant findings include: older age and higher American Society of Anesthesiology risk scores for revision THAs. Osteoarthritis is the most common diagnosis for THA and TKA, and aseptic loosening and instability are most common in revision THAs and TKAs. The TJRR has provided a mechanism for recalls, identified patients at risk for early revisions and changed practice by providing feedback to physicians.
凯撒医疗集团全国全关节置换登记处（TJRR）是一个国家级数据库，设计用作选择性全髋关节和膝关节置换的上市后监测系统。截至2007年3月31日，TJRR记录了16945例初次全髋关节置换术（THA），其中2144例翻修（11.2%）；以及30815例全膝关节置换术（TKA），其中1794例翻修（5.5%）。具有统计学意义的发现包括：翻修THA患者年龄较大且美国麻醉医师协会风险评分较高。骨关节炎是THA和TKA最常见的诊断，无菌性松动和不稳定在翻修THA和TKA中最为常见。TJRR提供了召回机制，识别出有早期翻修风险的患者，并通过向医生提供反馈改变了医疗行为。
