Investigation of patient satisfaction after primary total knee arthroplasty using posteriorstabilized implants

目的调查后稳定型人工全膝关节初次置换术后患者的总体满意度。方法选择行后稳定型人工全膝关节初次置换术患者1465例,术后1年给纳入研究的患者邮寄一份由笔者设计并验证的膝关节置换术满意度量表,其中包含对手术的总体满意度和对具体功能或症状缓解程度的15个分项满意度。收集患者作答后的量表并统计分析。结果 1173例患者(1588例膝关节置换)寄回了量表,总体满意度为87.3%,最不满意的6个分项为盘腿坐(不满意率55.2%)、下蹲(52.1%)、快走或慢跑(45.2%)、膝关节活动时有响声(34.6%)、膝关节感觉不自然(31.4%)和爬楼(28.7%)。结论后稳定型人工全膝关节初次置换术满意度较高,术后1年WOMAC疼痛分值对满意度有显著影响。
