Patellar resurfacing was performed by the authors. From 1983 to 1988, 19 cases (22 knees) with patello-femoral osteoarthritis were treated with this procedure in our hospital. Excellent and good results were recorded in 13 cases (59.1%) one year after operation, but were zero in the long-term follow-up (average 8.7 years) because of recurrent knee pain due to the wearing of the cortex of the femoral groove. Further operation was necessary for those cases, such as patellectomy or total knee replacement. Since 1991 Y-L-Q's type of patellofemoral replacement has been used in 11 cases in our department to alter the isolated resurfacing of the patella. The femoral groove was replaced with a metallic implant that allows sliding of a polyethylene patella to prevent the wearing of the femoral cortex. Preliminary results are good.
作者进行了髌骨表面置换术。1983年至1988年，我院采用该手术治疗了19例（22膝）髌股关节炎患者。术后1年，13例（59.1%）效果优良，但长期随访（平均8.7年）时优良率为零，原因是股骨髁皮质磨损导致膝关节反复疼痛。这些病例需要进一步手术，如髌骨切除术或全膝关节置换术。自1991年以来，我科使用Y-L-Q型髌股关节置换术治疗11例患者，以改变单纯的髌骨表面置换。用金属植入物替换股骨髁，该植入物允许聚乙烯髌骨滑动，以防止股骨皮质磨损。初步结果良好。
