摘　　要：目的:探讨采用微创内固定稳定系统(less invasive stabilization system,LISS)治疗全膝关节置换术后股骨髁上假体周围骨折的临床效果。方法:研究纳入2006年10月至2009年10月间收治的采用切开复位股骨远端LISS内固定治疗且获得完整随访资料的8例全膝关节置换术后股骨髁上假体周围骨折的患者,对患者术后的膝关节活动度、关节功能等进行评定。结果:随访时间3～39个月,平均11个月。8例患者未出现伤口感染,内固定松动、断裂,假体未见松动,至随访时骨折愈合好。患膝术后关节活动度平均为0～94°,患膝外翻角较术前无明显变化。膝关节功能平均HSS评分为79.38分,Lysholm评分为80.25分,优良率均为87.5%。结论:LISS是治疗全膝关节置换术后股骨髁上假体周围骨折一种有效的方法,结合植骨及早期功能锻炼,有利于患肢功能的早期恢复,结果满意。Objective：To investigate the clinical results of therapy of periprosthetic femoral supracondylar fractures after total knee arthroplasty（TKA） with open reduction and internal fixation（ORIF） using less invasive stabilization system（LISS）.Methods： Eight cases of periprosthetic femoral supracondylar fractures after TKA were treated with ORIF using distal femoral LISS in our department.They had full follow-up for 3 to 39 months.Their knee functions were evaluated through radiological and clinical checkups and functional evaluations by HSS（The Hospital for Special Surgery） scoring system and Lysholm Questionnaire.Results： None of the fractured patients had any infection or internal-fixation failure.The average knee motion range was 0-94°.There was no statistic difference of the femorotibial angle between pre-and postoperation.At the end of the last follow-up,the average HSS score was 79.38 and Lysholm score 80.25.All the average scores were good and excellent.Conclusion： ORIF with LISS is a one of the valuable treatments for periprosthetic femoral supracondylar fractures after TKA.
