中文摘要：

目的探讨应用真空负压引流术（VSD）、内侧腓肠肌皮瓣转移术治疗全膝关节置换（TKA）术后皮肤坏死，挽救TKA的疗效。方法2007年至2009年本组共有4例患者采用内侧腓肠肌皮瓣转移术治疗TKA术后伤口皮肤坏死，平均随访19个月（12—32个月），采用KSS膝关节评分系统进行功能评价，在最后随访时对患者的感染消除情况进行临床评价，测量患者活动度。结果根据KSS膝关节评分系统，4例患者结果优良。所有患者均有良好的股四头肌力量。患者不需要助步器行走，所有皮瓣一期愈合，无感染复发。结论内侧腓肠肌皮瓣能提供良好的覆盖，允许早期活动和快速康复，可以降低TKA术失败后关节僵硬的发生率。

英文摘要：

Objective To investigate the effect of vaccum sealing drainage （VSD） and medial gastrocnemius graft on skin necrosis after total knee arthroplasty. Methods Four patients were treated with medial gastrocnemius muscle flap transfer after TKA for wound problems between 2007 and 2009. The average follow-up time was 19 months （range 12 -32 months）. Functional evaluation was performed by the KSS knee rating scale. The patients were evaluated clinically for resolution of infection at final follow-up. Range of motion was measured with a goniometer. Results Four patients had excellent or good outcomes according to the KSS knee rating scale. All patients had good or excellent quadriceps strength. No patient required a walking aid for community ambulation. All patients had resolution of infection. All flaps healed primarily with no recurrence of infection. Conclusions The medial gastrocnemius muscle flap provides good quality coverage, permits early mobilization and fast rehabilitation, and reduces the rate of joint stiffness after failure of total knee arthroplasty.
