Survival analysis studies of 40 patients treated with high tibial osteotomy for arthritis with angular deformity were performed to determine the dominant factors that adversely affected long-term knee function. Obesity, advanced age, and postoperative overcorrection or undercorrection resulted in short durations of successful function. On the average, the probabilities for continued useful function of the knee at tested intervals were: one year, 86%; three years, 64%; five years, 50%; and nine years, 28%.
对40例行高位胫骨截骨术治疗伴有角形畸形关节炎患者进行生存分析研究，以确定对长期膝关节功能产生不利影响的主要因素。肥胖、高龄以及术后过度矫正或矫正不足均导致膝关节成功发挥功能的时间较短。平均而言，在各测试时间点膝关节持续保持有效功能的概率分别为：1年时86%；3年时64%；5年时50%；9年时28%。
