摘要 目的:为探索类风湿性关节炎患者的人工膝关节置换术手术疗效与并发症。方法:作者对44例62膝因严重类风湿性关节炎(RA)而施行人工膝关节置换术患者作了随访分析,患者最小年龄24岁,最大年龄86岁,平均年龄65岁。随访时间平均7.2年。结果:62膝中术前膝外翻大于5°者22膝(占35.5%),术前膝内翻大于5°者14膝(占22.5%),术后膝关节内外翻控制在0--3°以内。术后52膝(占84%)的假体维持原位并保护良好功能,膝关节HSS评分由术前平均33.4分提高至术后平均78.6分。另有7膝(占11.3%)发生各种机械性失败,3膝(占4.7%)发生感染性失败。结论:人工膝关节置换治疗类风湿性膝关节炎具有较好的中长期临床疗效,但其机械性失败率和感染性失败率均略高于退行性骨关节炎的全膝置换术。
