Eighty-nine knees with medial tibio-femoral and patellofemoral osteoarthritis were treated by high tibial osteotomy between 1972 and 1978, and 71 were followed up for at least 5 years, the average being 6 years and 9 months. There was no significant loss of motion as recorded before and after operation. In most patients pain decreased or disappeared, and walking ability was regained. Evaluation using the Japanese rating system showed that there were Good and Fair results in 86% of the cases. The average tibio-femoral angle in the Good group was 169 +/- 5 degrees. The angles in the Poor group varied over a wide range. There were serious complications such as nonunion, malunion and infection in a few cases. In Group 1 (30 knees) high tibial osteotomy alone was performed. In Group 2 (41 knees) there were associated osteoarthritic changes in the patellofemoral joint and a high tibial osteotomy was combined with anterior displacement of the tibial tubercle (ventralization). In comparison, Group 2 had better results with regard to both clinical and radiological evaluation.
1972年至1978年间，89例患有胫股内侧和髌股骨关节炎的膝关节接受了高位胫骨截骨术治疗，其中71例进行了至少5年的随访，平均随访时间为6年9个月。手术前后记录的活动度没有明显损失。大多数患者的疼痛减轻或消失，并恢复了行走能力。采用日本评分系统评估显示，86%的病例结果为良好和中等。良好组的平均胫股角为169±5度。差组的角度变化范围很广。少数病例出现了诸如骨不连、畸形愈合和感染等严重并发症。第1组（30例膝关节）仅进行了高位胫骨截骨术。第2组（41例膝关节）髌股关节存在相关骨关节炎改变，高位胫骨截骨术联合胫骨结节前移（腹侧化）。相比之下，第2组在临床和影像学评估方面都有更好的结果。
