A review of 34 knees with osteonecrosis of the medial femoral condyle treated by unicompartmental arthroplasty is presented, with a minimum of two years' follow-up time and an average of five-and-one-half years. Excellent or good results were obtained in 89% of the patients. Of the four failures reported, two were caused by the development of osteonecrosis of the lateral compartment. Two other patients had persistent pain with no apparent cause. Unicompartmental arthroplasty is acceptable treatment of osteonecrosis of the knee joint because of the rapid recovery from the operation, the low morbidity rate, and the preservation of the cruciate ligaments, the patella, and the opposite compartment, which results in better function and motion than a high tibial osteotomy or a total knee arthroplasty.
本文对34例采用单髁关节置换术治疗的股骨内侧髁骨坏死患者进行了回顾性研究，随访时间最短为两年，平均为五年半。89%的患者获得了优良效果。在报告的4例失败病例中，2例是由于外侧间室发生骨坏死所致。另外2例患者持续疼痛，原因不明。单髁关节置换术是膝关节骨坏死的可接受治疗方法，因为手术恢复快、发病率低，并且保留了交叉韧带、髌骨和对侧间室，这导致其功能和活动度优于高位胫骨截骨术或全膝关节置换术。
