On three occasions we have reviewed a series of knees after high tibial osteotomy for osteoarthritis: 99 were reviewed at one to two years; 81 at a mean of 5.7 years; and 65 at a mean of 11.9 years. At one to two years and at 5.7 years over 50% were good and over 75% acceptable. At 11.9 years, 43% were good and 60% acceptable. We determined the mechanical axis through the knee in maximum varus and maximum valgus; significantly better results were found if a mean angulation of 3 degrees to 7 degrees of valgus had been achieved at operation. We also measured intercondylar distances under varus and valgus stress, and found no significant lateral compartment narrowing. The best results were seen in knees with pre-operative grade I or grade II osteoarthritis and valgus deviation after osteotomy.
99例在术后1至2年进行复查；81例平均在术后5.7年进行复查；65例平均在术后11.9年进行复查。在术后1至2年以及5.7年时，超过50%的结果为良好，超过75%的结果可接受。在术后11.9年时，43%的结果为良好，60%的结果可接受。我们测定了膝关节在最大内翻和最大外翻时的机械轴；如果在手术中实现了平均3度至7度的外翻成角，则结果明显更好。我们还测量了在内翻和外翻应力下的髁间距离，未发现外侧间室有明显变窄。术前为I级或II级骨关节炎且截骨术后有外翻畸形的膝关节效果最佳。
