Revision total knee arthroplasty (TKA) is a challenging surgical procedure. Although good results are presented, the outcomes are worse in comparison with those of primary TKA, with a higher failure rate. The main reasons for the failure of revision TKA include: sepsis, loosening and instability. There are multiple variables linked to these results, and it is difficult to determinate the exact cause as it is often a multifactorial issue. These variables may be related to the quality of the index-procedure (TKA), to the revision procedure or to patient characteristics. The purpose of this review was to highlight the outcomes of revision knee arthroplasty and main factors that may influence the results. Considerable progress has been made during the last 30 years regarding infection treatment and prevention, complex revision prosthetic design and surgical technique development. Although the outcomes have improved over time, patients who undergo revision TKA may need further re-operations in the future.
全膝关节置换翻修术（TKA）是一项具有挑战性的外科手术。尽管有良好的结果报道，但与初次全膝关节置换术相比，其结果更差，失败率更高。全膝关节置换翻修术失败的主要原因包括：感染、假体松动和不稳定。有多个变量与这些结果相关，很难确定确切原因，因为这往往是一个多因素问题。这些变量可能与初次手术（全膝关节置换术）的质量、翻修手术或患者特征有关。本综述的目的是强调膝关节置换翻修术的结果以及可能影响结果的主要因素。在过去30年中，在感染治疗与预防、复杂翻修假体设计和手术技术发展方面取得了相当大的进展。尽管随着时间推移结果有所改善，但接受全膝关节置换翻修术的患者未来可能仍需要进一步的再次手术。
