The cases of twenty-one consecutive patients who had a minimally constrained total knee arthroplasty (six of whom had a cemented and fifteen, an uncemented prosthesis) after a failed proximal tibial osteotomy for osteoarthritis were compared with those of a non-consecutive group of twenty-one patients who had had a primary total knee arthroplasty for osteoarthritis. The groups were matched according to age and sex of the patient, type of prosthesis and fixation, and length of follow-up. At an average length of follow-up of 2.9 years, a good or excellent result was obtained in 81 per cent of the patients who had had a previous osteotomy. At an average length of follow-up of 2.8 years, a good or excellent result was obtained in 100 per cent of the patients who had had a primary arthroplasty. Two patients in the osteotomy group and none in the primary arthroplasty group required additional surgery. At the time of arthroplasty, technical difficulties in exposing the proximal part of the tibia were noted in three patients in the group that had undergone an osteotomy. The results of total knee arthroplasty after failed proximal tibial osteotomy approached but did not equal the results after primary total knee arthroplasty.
将21例因骨关节炎行胫骨近端截骨术失败后接受微创全膝关节置换术的连续患者（其中6例使用骨水泥型假体，15例使用非骨水泥型假体）与21例因骨关节炎接受初次全膝关节置换术的非连续患者进行比较。根据患者的年龄、性别、假体类型及固定方式、随访时间对两组进行匹配。在平均随访2.9年时，曾接受截骨术的患者中有81%获得了良好或优秀的结果。在平均随访2.8年时，接受初次置换术的患者中有100%获得了良好或优秀的结果。截骨术组有2例患者需要再次手术，初次置换术组无患者需要再次手术。在进行置换术时，截骨术组有3例患者在暴露胫骨近端时遇到技术困难。胫骨近端截骨术失败后行全膝关节置换术的结果接近但未达到初次全膝关节置换术的结果。
