本文报告了10例（12膝）膝关节内翻畸形平均24 °（范围20 ° ~ 40 °）的患者行全膝关节置换术（TKA）的临床和影像学结果。我们描述了一种技术，即减小胫骨部件的尺寸并使其外侧化，随后取出胫骨近端内侧，使其与减小的部件齐平。平均随访42个月（范围：12 - 64个月）时，平均术前膝关节协会评分和功能评分分别从24和34改善至随访时的94和85。未对植入物进行翻修。在随访评价时，未观察到骨质溶解或放射学松动的证据，平均胫股角为4度外翻。该技术为严重内翻畸形患者提供了中期稳定的矫正和出色的临床和影像学结果。
The clinical and radiologic outcome of 10 patients (12 knees) with a mean varus deformity of 24degrees (range, 20degrees to 40degrees) 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 4degrees of valgus. This technique provides mid-term stable correction and excellent clinical and radiographic results in patients with severe varus deformity.
