Abstract：
BACKGROUND: International joint registries provide high volumes of information in relation to the performance of total knee arthroplasty on a global scale. Distillation of this data can be challenging, particularly with the establishment of more arthroplasty registries on a yearly basis. We therefore aim to present key information from these registries in relation to primary total knee arthroplasty. The specific questions of interest include: Which fixation type is superior in TKA? Does the level of constraint impact on clinical performance? How do partial knee replacements perform in the registries? Does patellar resurfacing lead to superior results? Are there any specific implants which perform particularly well or poorly?
METHODS: A comprehensive review of the major English-speaking knee arthroplasty registries across the globe was performed. Given the expanding large number of registries worldwide, it was not possible to perform a comprehensive review of all registries and so, a detailed review of the major English-speaking knee arthroplasty registries was included. Key trends and developments in implant performance were identified and presented in the current article.
RESULTS: Total knee replacements have lower revision rates than both unicompartmental and patellofemoral joint replacement procedures. Patellofemoral joint replacements have the highest failure rate of all knee replacement procedures. Cruciate-Retaining (CR) TKR designs have superior outcomes to Posterior-Stabilized (PS) designs across all registries. Patellar resurfacing appears to confer an advantage over non-resurfaced patellas in primary TKR.
CONCLUSIONS: We present current global trends in the utility and performance of TKA based on data from English-speaking arthroplasty registries.

摘要：
背景：国际关节注册在全球范围内提供了与全膝关节置换术有关的大量信息。这些数据的蒸馏可能具有挑战性，特别是随着每年建立更多的关节成形术登记处。因此，我们旨在从这些注册表中提供与初次全膝关节置换术有关的关键信息。感兴趣的具体问题包括：哪种固定类型在TKA中更胜一筹？约束水平对临床表现有影响？部分膝关节置换在注册中的表现如何？髌骨重修会导致更好的结果吗？是否有特定的植入物表现特别好或不好？
方法：对全球主要的英语膝关节置换注册进行了全面审查。鉴于全球注册管理机构的数量不断扩大，不可能对所有登记册进行全面审查，因此，我们对主要的英语膝关节置换术注册进行了详细的回顾.本文确定并介绍了植入物性能的主要趋势和发展。
结果：全膝关节置换手术的翻修率低于单室和髌股关节置换手术。在所有膝关节置换手术中，髌股关节置换的失败率最高。交叉保留（CR）TKR设计在所有注册表中都比后路稳定（PS）设计具有更好的结果。在原发性TKR中，髌骨重铺似乎比未重铺的髌骨具有优势。
结论：我们基于来自英语关节成形术注册的数据，介绍了TKA的效用和性能的当前全球趋势。
