Efficacy analysis of non-limiting total knee prosthesis in the application of knee stiff

目的探讨采用非限制型全膝关节假体治疗僵直型膝关节的临床疗效。方法选择2011年6月至2013年6月收治的17例僵直型膝关节患者的临床资料，全部患者均给予应用非限制型全膝关节假体手术治疗。结果本组患者手术时间（91±11）min，手术失血量（350±45）ml，术后仅1例患者出现切口边缘少许发黑现象。给予全部患者6周～1年随访，患者治疗前后膝关节屈曲与HSS评分比较差异有统计学意义（P〈0．05）。结论采用非限制性全膝关节假体治疗僵直型膝关节，疗效较为满意，是较为有效的治疗方法。
