2、例患者均确诊为膝关节置换术后深部感染,2例为甲氧西林敏感金黄色葡萄球菌感染,1例为大肠杆菌感染,1例为表皮葡萄球菌感染。入院后根据细菌培养药敏试验使用抗生素i~2w,并行膝关节融合术。手术采用原切口,取出假体,彻底冲洗,将股骨远端与胫骨近端融人膝关节屈曲1O。、外翻5。,1例采用交叉克氏针内固定加外固定架固定,3例采用髌前(皮肤外)锁定钢板固定。一期缝合皮肤或肌瓣转移二期游离植皮。术后继续使用抗生素(术前、术后共4~6w)。结果4例患者随访6月~5年,伤口均一期愈合,无窦道形成,术后查CRP、WBC、USR均正常,膝关节在5~8月一期融合,手术肢体平均短缩4.5cm,患者跛行,无疼
3、痛,能够室内日常生活。结论一期关节融合治疗全膝关节置换术后深部感染安全、简便、效果可靠,适于伸膝装置受损、皮肤缺损较大、对肢体功能要求不高、全身情况差以及经济困难患者,但会遗留较大残疾。【关键词】融合;全膝关节置换术;感染【中图分类号】R687.4【文献标志码】BTheArthrodesisTreatsoftheInfectionAftertheTotalKneeArthroplastyJIANGTao,HEJun,LINYahjing,XIANGDeng,LIUJin—wang,ZHAOWen,LINYang—shui.DepartmentofOrthopedicandJoint
