Abstract：
Objectives The aim of this is to investigate the changes in body mass index (BMI) following knee arthroplasty and to evaluate their impact on patient-reported outcomes and functional evaluations. Methods This observational study included 90 patients who underwent total knee arthroplasty (TKA) and were followed up for a median period of 2.6 years. BMI measurements were recorded before and after surgery, and patient-reported outcomes and functional evaluations were assessed using standardized scales and tests. Results Following TKA, BMI increased statistically significantly (Wilcoxon signed-rank test, p < 0.000). In addition, half of the patients experienced an increase in BMI, with 32% moving up in their BMI category. However, there were no clinically significant differences in patient-reported outcomes or functional evaluations between the group that gained BMI and the group that maintained or lost BMI. Conclusion This study reveals that patients tend to have increased BMI following TKA. However, these BMI changes do not significantly impact patient-reported outcomes or functional evaluations. It underscores the importance of patient education regarding healthy lifestyle habits, including diet and physical activity, to address postoperative weight gain effectively.
摘要：
目的研究膝关节置换术后体重指数（BMI）的变化，并评估其对患者报告的结局和功能评估的影响。方法这项观察性研究包括90例接受全膝关节置换术（TKA）的患者，中位随访时间为2.6年。在手术前后记录BMI测量值，使用标准化量表和测试对患者报告的结局和功能评价进行评估.TKA后的结果，BMI显著增加(Wilcoxon符号秩检验，p<0.000)。此外,一半的患者经历了BMI的增加，32%的人在他们的BMI类别中上升。然而,增加BMI的组与维持或丢失BMI的组之间,患者报告的结局或功能评估无临床显著差异.结论本研究揭示了TKA后患者的BMI倾向于增加。然而,这些BMI变化对患者报告的结局或功能评估无显著影响.它强调了对患者进行健康生活习惯教育的重要性，包括饮食和体力活动，有效解决术后体重增加问题。
