We describe the mid-term results of a prospective study of total knee replacement in severe valgus knees using an osteotomy of the lateral femoral condyle and computer navigation. There were 15 knees with a mean valgus deformity of 21 degrees (17 degrees to 27 degrees) and a mean follow-up of 28 months (24 to 60). A cemented, non-constrained fixed bearing, posterior-cruciate-retaining knee prosthesis of the same design was used in all cases (Columbus-B. Braun; Aesculap, Tuttlingen, Germany). All the knees were corrected to a mean of 0.5 degrees of valgus (0 degrees to 2 degrees). Flexion of the knee had been limited to a mean of 85 degrees (75 degrees to 110 degrees) pre-operatively and improved to a mean of 105 degrees (90 degrees to 130 degrees) after operation. The mean Knee Society score improved from 37 (30 to 44) to 90 points (86 to 94). Osteotomy of the lateral femoral condyle combined with computer-assisted surgery gave an excellent mid-term outcome in patients undergoing total knee replacement in the presence of severe valgus deformity.
我们描述了一项前瞻性研究的中期结果，该研究采用股骨外侧髁截骨术和计算机导航技术对严重膝外翻患者进行全膝关节置换。共有15例膝关节，平均外翻畸形21度（17度至27度），平均随访28个月（24至60个月）。所有病例均使用相同设计的骨水泥固定、非限制性固定承重、后交叉韧带保留型膝关节假体（Columbus - B. Braun；德国图特林根市蛇牌）。所有膝关节均矫正至平均外翻0.5度（0度至2度）。术前膝关节屈曲平均受限至85度（75度至110度），术后改善至平均105度（90度至130度）。膝关节协会平均评分从37分（30至44分）提高到90分（86至94分）。对于存在严重外翻畸形的全膝关节置换患者，股骨外侧髁截骨术联合计算机辅助手术取得了优异的中期效果。
