Despite substantial advances in primary TKA, numerous studies using historic TKA implants suggest only 82% to 89% of primary TKA patients are satisfied. We reexamined this issue to determine if contemporary TKA implants might be associated with improved patient satisfaction. We performed a cross-sectional study of patient satisfaction after 1703 primary TKAs performed in the province of Ontario. Our data confirmed that approximately one in five (19%) primary TKA patients were not satisfied with the outcome. Satisfaction with pain relief varied from 72-86% and with function from 70-84% for specific activities of daily living. The strongest predictors of patient dissatisfaction after primary TKA were expectations not met (10.7x greater risk), a low 1-year WOMAC (2.5x greater risk), preoperative pain at rest (2.4x greater risk) and a postoperative complication requiring hospital readmission (1.9x greater risk).

摘要：尽管初次全膝关节置换术取得了重大进展，但许多使用历史上全膝关节置换术植入物的研究表明，只有 82%至 89%的初次全膝关节置换术患者感到满意。我们重新研究了这个问题，以确定现代全膝关节置换术植入物是否可能与改善患者满意度相关。我们对安大略省进行的 1703 例初次全膝关节置换术患者进行了一项横断面研究。我们的数据证实，大约五分之一（19%）的初次全膝关节置换术患者对结果不满意。对疼痛缓解的满意度从 72%到 86%不等，对特定日常生活活动的功能的满意度从 70%到 84%不等。初次全膝关节置换术后患者不满意的最强预测因素是期望未得到满足（风险增加 10.7 倍）、1 年 WOMAC 评分低（风险增加 2.5 倍）、术前静息时疼痛（风险增加 2.4 倍）和术后需要住院治疗的并发症（风险增加 1.9 倍）。
