摘要(Abstract)：

[目的]探讨二期翻修手术治疗膝关节假体周围感染的有效性、失败原因和骨水泥活动间隔物对二期置换术后膝关节功能的影响。[方法]回顾性分析2010年1月~2012年12月因膝关节假体周围感染而行二期翻修手术的病例21例,分析失败原因,比较术前术后患者膝关节评分(KSS)和膝关节活动度。[结果]2例真菌感染病例1例因一期手术后不能控制感染,1例因二期翻修手术后再次发生感染而最终行膝关节融合术。其余19例患者二期手术后平均随访31个月(19~44个月),二期清创膝关节翻修术获得成功。术后KSS膝关节评分、KSS功能评分和膝关节活动度比术前都有明显提高。[结论]膝关节假体周围感染通过一期清创、带抗生素活动型骨水泥间隔物置入、二期翻修手术可以有效治疗感染并重建膝关节功能,而真菌引起的感染是造成手术失败的原因之一。
