National joint replacement registries were developed for prospective monitoring of outcomes and post-market surveillance of implants. Increasingly registry data informs practice. However, analysis of a registry can only be as good as the data it captures on the population of interest. We aimed to analyze completeness of reporting of hip and knee replacement procedures for all national registries worldwide.
We analyzed annual reports and data provided following written requests to all active national hip and knee replacement registries. Coverage was defined as the proportion of hospitals in the country that participate in the registry. Procedure completeness was defined as the proportion of procedures successfully captured by the registry.
14 national registries were included, spanning years 2004 to 2022. Coverage was complete in 10. Median procedure completeness for primary hip and knee replacement across all years was 96.5% (interquartile range [IQR] 94.0-97.7%). Median procedure completeness for revisions was 88.5% (IQR 81.0-92.5%). The terminology used and method of calculation of completeness estimates in the registries were variable.
National hip and knee replacement registry data generally reflects excellent coverage (full in 10 of 14 registries) and completeness (primary procedures 96.5% and revisions 88.5%) over the last 2 decades.
国家关节置换登记处是为前瞻性监测结果和植入物上市后监测而设立的。越来越多的登记处数据为实践提供信息。然而，对登记处的分析只能与它对目标人群所捕获的数据一样好。我们旨在分析全球所有国家髋关节和膝关节置换登记处报告的程序的完整性。
我们分析了年度报告和根据书面请求向所有活跃的国家髋关节和膝关节置换登记处提供的数据。覆盖率定义为参与登记处的医院比例。程序完整性定义为登记处成功捕获的程序比例。
共纳入 14 个国家登记处，涵盖 2004 年至 2022 年。10 个国家的登记处覆盖率完整。所有年份的原发性髋关节和膝关节置换的程序完整性中位数为 96.5%（四分位距[IQR]94.0-97.7%）。翻修手术的程序完整性中位数为 88.5%（IQR 81.0-92.5%）。登记处中使用的术语和计算完整性估计的方法各不相同。
在过去的 20 年里，国家髋关节和膝关节置换登记处的数据通常反映出出色的覆盖率（14 个登记处中有 10 个完整）和完整性（原发性手术 96.5%，翻修手术 88.5%）。
