From 1974 to 1981, we performed 28 core decompressions of the distal femur for pathologically confirmed avascular necrosis. At a mean follow-up of 54 months (range 20 to 140 months) and using the Ficat stages, all seven cases in stage I and stage II had good results. Of 21 cases in stage III, 11 cases had good results, four had poor results, and six needed total knee replacement. There were no significant orthopaedic complications. The procedure is worthwhile and will be more accurate with new methods of imaging.
1974年至1981年期间，我们对经病理证实为缺血性坏死的股骨远端进行了28次髓芯减压术。平均随访54个月（范围20至140个月），采用菲卡特分期，I期和II期的所有7例患者效果良好。III期的21例患者中，11例效果良好，4例效果不佳，6例需要进行全膝关节置换。未出现明显的骨科并发症。该手术是值得的，并且随着新的成像方法将更加精确。
