High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis of the knee with varus malalignment. The outcome of total knee arthroplasty (TKA) after HTO remains uncertain. The aim of this paper is to revise the literature with the aim of answering the following question: Does a previous (HTO) influence the long-term function or survival of a TKA?. The search engine was MedLine. The keywords used were: total knee arthroplasty after high tibial osteotomy. One hundred and ten articles were found. Of those, only 19 were selected and reviewed because they were strictly focused on the topic and the question of this article. The reports published so far have a low grade of evidence (levels III and IV). Most of them are prospective case series (level IV). One is a systematic review of level III studies reported in 2009. Two recent studies based in a great number of cases (registers) showed similar survival in the 2 groups: around 92% at 10 years, and 88% at 15 years. The review of the literature suggests that a previous HTO does not influence the function or survival of a TKA in the long-term. III.
高位胫骨截骨术（HTO）是治疗伴有内翻畸形的膝关节内侧骨关节炎的一项成熟技术。HTO术后全膝关节置换术（TKA）的结果仍不确定。本文的目的是对文献进行综述，以回答以下问题：既往的HTO是否会影响TKA的长期功能或生存率？检索引擎为MedLine。使用的关键词为：高位胫骨截骨术后全膝关节置换术。共找到110篇文章。其中，仅19篇被选中并进行综述，因为它们严格聚焦于本文的主题和问题。目前发表的报告证据等级较低（III级和IV级）。大多数是前瞻性病例系列（IV级）。其中一篇是2009年报道的III级研究的系统综述。两项基于大量病例（登记数据）的近期研究显示两组的生存率相似：10年时约为92%，15年时约为88%。文献综述表明，既往的HTO在长期内不会影响TKA的功能或生存率。III.
