It is debatable whether or not previous high tibial osteotomy (HTO) has negative effects on the results of subsequent medial unicompartmental knee replacement (UKR). The purpose of this study is to report, through a systematic review of the literature, the outcomes of medial UKR after failed HTO. It was hypothesized that this procedure would be safe and effective in providing satisfactory postoperative functional outcomes.

胫骨高位截骨失败后，内侧单髁膝关节置换术是一种可行的治疗选择：系统评价。

先前的胫骨高位截骨术（HTO）是否对随后的内侧单髁膝关节置换术（UKR）的结果产生负面影响是有争议的。本研究的目的是通过对文献的系统回顾，报告 HTO 失败后内侧 UKR 的结果。假设该程序在提供令人满意的术后功能结果方面是安全和有效的。
