A series of 17 primary total hip arthroplasties in patients with juvenile rheumatoid arthritis (JRA) were performed at a mean age of 18 years with an average follow-up period of 9.3 years. There were 13 cemented prostheses and four noncemented. All patients were satisfied with their hip surgery and reported either slight or no hip pain according to the Harris hip rating system. Ambulation improved postoperatively and all but one patient was at least a limited community ambulator (able to ambulate short distances outside the home with crutches, walker, or cane). Roentgenogram evaluation showed five cemented hips that were believed to be definitely loose with impending failure. All were functioning well. One acetabular component has been revised to date. No femoral components have been revised. The four noncemented hips with an average follow-up period of five years were functioning well.
对17例幼年类风湿性关节炎（JRA）患者进行了初次全髋关节置换术，平均年龄为18岁，平均随访期为9.3年。其中有13个骨水泥型假体和4个非骨水泥型假体。根据Harris髋关节评分系统，所有患者对髋关节手术均满意，报告髋关节疼痛轻微或无疼痛。术后行走能力有所改善，除1例患者外，所有患者至少是有限的社区行走者（能够借助拐杖、助行器或手杖在家外短距离行走）。X线片评估显示，5个骨水泥型髋关节被认为肯定松动且即将失败。但所有髋关节功能良好。迄今为止，有1个髋臼部件已进行翻修。尚无股骨部件进行翻修。4个非骨水泥型髋关节平均随访5年，功能良好。
