From 1970 to 1978, 29 patients had a unilateral operation for bilateral recurrent dislocation of the patella. We examined 21 of them at a mean of 14 years postoperatively. Eighteen of these patients had evidence of generalised joint laxity. Six of the operated knees and four of the unoperated knees still had recurrent dislocations. The operated knees were clinically worse, with a significantly higher incidence of osteoarthritis. We concluded that the operations used to treat recurrent dislocation of the patella may have had short-term benefits, but did not cure the patients in the long term.
1970年至1978年期间，29例双侧复发性髌骨脱位患者接受了单侧手术。我们对其中21例患者进行了检查，术后平均随访14年。这些患者中有18例存在全身关节松弛的证据。6例接受手术的膝关节和4例未接受手术的膝关节仍有复发性脱位。接受手术的膝关节临床情况更差，骨关节炎发病率显著更高。我们得出结论，用于治疗复发性髌骨脱位的手术可能有短期益处，但从长期来看并不能治愈患者。
