背景：全膝关节置换术（TKA）是一种治疗膝关节疾病的成熟手术。然而，术后活动度（ROM）各不相同，是TKA成功的重要指标。最近，患者报告的结果指标（PROM）和患者满意度引起了人们的关注。然而，ROM和膝关节功能获得PROM和satisfactions.Methods：我们回顾性分析了375例患者进行了500次初次TKA手术的数据之间的关系。我们测量了手术前后的ROM。使用膝关节损伤骨关节炎结局评分（PROM）评估膝关节功能，并将患者分为功能良好组和功能不良组。采用5级量表评价患者满意度作为总体满意度，并根据获得的评分将患者分为满意组和不满意组。比较两组患者ROM的差异，并对差异有统计学意义的因素进行多因素Logistic回归分析。结果：术后膝关节屈曲角度对膝关节功能有显著影响（P
Background: Total knee arthroplasty (TKA) is a well-established procedure for treating knee joint diseases. However, the postoperative range of motion (ROM) varies and is an important indicator of TKA success. Recently, patient-reported outcome measures (PROMs) and patient satisfaction have drawn attention. However, the relationship between ROM and knee function obtained by PROM and satisfaction is not well understood.Methods: We retrospectively reviewed the data of 375 patients who underwent 500 primary TKA procedures. We measured the ROM before and after surgery. Knee joint function was evaluated using the Knee Injury Osteoarthritis Outcome Score, a PROM, and patients were classified into good function and poor function groups. Patient satisfaction was evaluated on a 5-graded scale as overall satisfaction, and patients were divided into a satisfied or a dissatisfied group according to the obtained scores. ROM was compared between the 2 groups, then significantly different factors were analyzed using multiple logistic regression analysis. Moreover, cut-off points of ROM for obtaining good function and patient satisfaction were determined using ROC curve analysis.Results: The postoperative flexion angle had a significant effect on knee function (P
