A retrospective matched-pair comparative analysis was done between 30 total knee arthroplasties following failed high tibial osteotomies and 30 total knee arthroplasties following failed unicompartmental knee arthroplasties. The groups were matched according to age, gender, type of prosthesis, primary disease, and length of followup. A minimum followup of 2 years was required for inclusion in the study, and the average followup was 3.8 years (range, 2-9 years). The Knee Society Knee Score for the high tibial osteotomy group was significantly higher than that for the unicompartmental arthroplasty group. More osseous reconstructions were required in the unicompartmental revisions. Difficulty with exposure was not significantly greater in the osteotomy group. Rates of component loosening were not significantly different between the groups. A failed unicompartmental knee arthroplasty and a failed high tibial osteotomy can be revised successfully to a total knee arthroplasty. The results confirm that revisions after unicondylar arthroplasty and high tibial osteotomy are technically demanding. In this series, the results of total knee arthroplasty following unicompartmental knee arthroplasty approached but did not equal those obtained after high tibial osteotomy.
对30例高位胫骨截骨术失败后行全膝关节置换术的患者与30例单髁膝关节置换术失败后行全膝关节置换术的患者进行了回顾性配对比较分析。根据年龄、性别、假体类型、原发性疾病和随访时间对两组进行匹配。纳入研究要求最短随访2年，平均随访时间为3.8年（范围2 - 9年）。高位胫骨截骨术组的膝关节协会膝关节评分显著高于单髁关节置换术组。单髁翻修术中需要更多的骨重建。截骨术组的暴露难度没有显著增加。两组之间假体松动率没有显著差异。失败的单髁膝关节置换术和失败的高位胫骨截骨术都可以成功翻修为全膝关节置换术。结果证实，单髁关节置换术和高位胫骨截骨术后的翻修在技术上要求较高。在本系列研究中，单髁膝关节置换术后全膝关节置换术的结果接近但不等于高位胫骨截骨术后的结果。
