Seventy-four patients, age 75 or older, who had undergone 98 primary total knee arthroplasties were evaluated in a retrospective cohort study, with validated questionnaires that assessed self-reported pain, physical function, mental health, and satisfaction. Average follow-up period was 34 months (range, 12-67 months). Overall, 90.8% reported improvement, 88.8% were satisfied with the results of surgery, and 91.8% felt they had made the right decision. Dissatisfaction with the results correlated with poorer mental health scores, decreased physical function, and increased bodily pain scores (P < .05). Satisfaction was correlated with better pain scores on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and SF-36 (P < .05) but not with Hospital for Special Surgery scores (P = .328). Poor surgical results leading to revision surgery (5%) were associated with preoperative deformity greater than 20 degrees. Based on this patient-assessed outcome analysis, total knee arthroplasty is a worthwhile and beneficial procedure in the elderly.
在一项回顾性队列研究中，对74名年龄在75岁及以上、接受了98次初次全膝关节置换术的患者进行了评估，采用经过验证的问卷来评估自我报告的疼痛、身体功能、心理健康和满意度。平均随访期为34个月（范围为12 - 67个月）。总体而言，90.8%的患者报告病情有所改善，88.8%的患者对手术结果满意，91.8%的患者认为自己做出了正确的决定。对结果的不满意与较差的心理健康评分、身体功能下降和身体疼痛评分增加相关（P < 0.05）。满意度与西安大略和麦克马斯特大学骨关节炎指数（WOMAC）以及SF - 36上更好的疼痛评分相关（P < 0.05），但与特种外科医院评分无关（P = 0.328）。导致翻修手术（5%）的手术效果不佳与术前畸形大于20度有关。基于这种患者评估的结果分析，全膝关节置换术对老年人来说是一项值得且有益的手术。
