Total knee arthroplasty (TKA) for preservation of ambulation is indicated in young adults with juvenile rheumatoid arthritis (JRA). The bony deformities of JRA require special measures to adequately seat the prosthesis. Thirteen patients with 25 knee arthroplasties were followed an average of 61 months. Prior surgical operations did not affect the outcome of this procedure. A 55% reduction in pain plus an average 30-point gain on Jergesen's functional assessment scale reflected the overall improvement attributable to TKA. To date, no revisions, infections, or loosenings have occurred in this series of patients.
对于患有幼年类风湿性关节炎（JRA）的年轻成年人，全膝关节置换术（TKA）用于保留行走能力。JRA的骨畸形需要采取特殊措施来妥善安置假体。对13例患者的25次膝关节置换术进行了平均61个月的随访。先前的手术操作并未影响该手术的结果。疼痛减轻55%，加上Jergesen功能评估量表平均提高30分，反映了TKA带来的总体改善。迄今为止，该系列患者未发生翻修、感染或松动情况。
