Total knee arthroplasty (TKA) is a cost effective and extremely successful operation. As longevity increases, the demand for primary TKA will continue to rise. The success and survivorship of TKAs are dependent on the demographics of the patient, surgical technique and implant-related factors. Currently the risk of failure of a TKA requiring revision surgery ten years post-operatively is 5%. The most common indications for revision include aseptic loosening (29.8%), infection (14.8%), and pain (9.5%). Revision surgery poses considerable clinical burdens on patients and financial burdens on healthcare systems. We present a current concepts review on the epidemiology of failed TKAs using data from worldwide National Joint Registries.
全膝关节置换术（TKA）是一种性价比高且极为成功的手术。随着寿命延长，初次全膝关节置换术的需求将持续上升。全膝关节置换术的成功及假体生存率取决于患者的人口统计学特征、手术技术和植入物相关因素。目前，全膝关节置换术后十年需要翻修手术的失败风险为5%。翻修的最常见指征包括无菌性松动（29.8%）、感染（14.8%）和疼痛（9.5%）。翻修手术给患者带来了相当大的临床负担，也给医疗系统带来了经济负担。我们利用来自全球各国关节登记处的数据，对失败的全膝关节置换术的流行病学进行了一次当前概念综述。
