摘    要:目的探讨后方稳定型膝关节置换术(PSKA)治疗膝关节骨关节炎的术后疗效及其受影响的因素。方法1998年1月~2007年4月,应用PSKA对67例(110膝)骨关节炎患者行手术。以术后膝关节功能(HSS)评分和各单项评分的改善率评定PSKA术后疗效;采用Pearson相关分析对PSKA术后HSS评分与术前患者自身的有关因素进行相关性分析。结果67例患者获随访14~120个月;平均47个月。术后膝关节HSS评分、疼痛、功能、关节活动度、肌力、屈曲畸形及稳定性评分分别为(85.06±9.53)分,(24.55±5.13)分,(17.94±3.01)分,(12.94±1.21)分,(9.91±0.42)分,(9.90±0.65)分,(9.88±0.10)分,均较术前均有不同程度改善(P〈0.05)。疗效评定优良率为98.18%。10膝发生局部并发症。随访1年有并发症的患者膝关节优良率(60.00%)明显低于无并发症患者(98.70%)(P〈0.05),随访2年二者无明显差异。相关分析显示PSKA术后HSS评分与单/双膝接受PSKA、术后康复方式、膝关节术前HSS评分、疼痛和功能评分相关(P〈0.05);而与患者术前关节活动度、肌力、屈曲畸形、稳定性、年龄、体重和体重指数等无相关(P〉0.05)。结论采用PSKA是治疗重症膝关节骨性关节炎的有效方法。术后疗效与单/双膝接受PSKA、术后半年康复方式有关,与术前膝关节HSS评分、疼痛和功能评分呈正相关;并发症的发生对术后1年疗效有明显负面影响,2年以上则无关。
