A long-term follow-up study is presented of 162 patients who were treated for knee arthrosis with proximal tibial osteotomy, 10 of whom had undergone a bilateral operation. The average follow-up time was 8 years. Pre-operatively, varus deformity was found in the knees of 117 patients; 45 of them had valgus knees. In 142 knees curved osteotomy was performed and wedge osteotomy in 30. At follow-up, 33% of the patients were found to have no pain. Significant long-term improvement was achieved, as registered at the time of follow-up, in 80% of the patients, whereas in 11% pain remained unchanged. Better results were recorded in women than in men (P less than 0.01). In the present study, slightly better results were obtained statistically using curved osteotomy (P less than 0.05). Postoperative plaster sleeve immobilisation for approximately 6 weeks (10 weeks at the most) gave the best results. Internal fixation seemed unnecessary.
本文介绍了一项针对162例行胫骨近端截骨术治疗膝关节骨性关节炎患者的长期随访研究，其中10例接受了双侧手术。平均随访时间为8年。术前，117例患者的膝关节存在内翻畸形；其中45例为外翻膝。142例膝关节行弧形截骨术，30例行楔形截骨术。随访时，33%的患者无疼痛。随访时记录显示，80%的患者获得了显著的长期改善，而11%的患者疼痛无变化。女性的结果优于男性（P<0.01）。在本研究中，使用弧形截骨术在统计学上获得了稍好的结果（P<0.05）。术后石膏套筒固定约6周（最长10周）效果最佳。似乎无需内固定。
