The clinical and radiologic outcome of 10 patients (12 knees) with a mean varus deformity of 24 degrees (range, 20 degrees to 40 degrees ) treated with total knee arthroplasty (TKA) is presented. We describe a technique of downsizing and lateralizing the tibial component with subsequent removal of the proximal medial tibia flush with the downsized component. At a mean follow-up of 42 months (range, 12 to 64 months), the mean preoperative Knee Society and function scores had improved from 24 and 34 to 94 and 85, respectively, at follow-up. No implant has been revised. At follow-up evaluation, no evidence of osteolysis or radiographic loosening was seen and the mean tibiofemoral angle was 4 degrees of valgus. This technique provides mid-term stable correction and excellent clinical and radiographic results in patients with severe varus deformity.
本文报告了10例（12膝）平均内翻畸形24度（范围为20度至40度）患者接受全膝关节置换术（TKA）后的临床和影像学结果。我们描述了一种缩小并外移胫骨组件，随后将胫骨近端内侧与缩小后的组件齐平切除的技术。平均随访42个月（范围为12至64个月）时，随访时膝关节协会（Knee Society）术前平均评分和功能评分分别从24分和34分提高到了94分和85分。没有进行植入物翻修。在随访评估中，未发现骨溶解或影像学松动的证据，平均胫股角为外翻4度。该技术为重度内翻畸形患者提供了中期稳定的矫正效果以及出色的临床和影像学结果。
