摘要

目的评估基线、全膝关节置换术（TKA）后1年以及TKA后至少5年的身体机能测试（PPTs）和患者报告的结果测量（PROMs）的变化。方法：我们招募了2013年至2015年间在泰国曼谷玛希隆大学Siriraj医院由一名关节置换外科医生进行TKA的患者。我们在至少5年的随访期间评估了PPT和prom，以评估随时间的变化，确定与PPT恶化相关的独立因素，并确定TKA生存率。结果研究纳入126名参与者，平均年龄77.8岁。平均随访时间7.4±2.3年。随着时间的推移，PPTs和prom从基线开始发生了显著变化。然而，2分钟步行测试和定时起跑测试结果在1年后略有下降，但没有达到最小的临床重要差异，PROMs在1年后保持不变，没有临床显着变化。由于复杂的医疗条件或创伤而住院与PPT恶化独立相关。7.6年生存率为98.8%。结论在亚洲接受TKA的人群中，原发性TKA后，PPTs和PROMs维持在可接受范围内至少5年。创伤或住院治疗引起的复杂的医疗条件被发现与功能下降有关。建议对TKA后患者进行PPTs和PROMs的综合评估。证据水平：III级队列研究。

Physical Performance and Patient-Reported Outcomes Remain Stable at 5 Years After Total Knee Arthroplasty

Purpose

To evaluate changes in physical performance tests (PPTs) and patient-reported outcome measures (PROMs) at baseline, 1 year after total knee arthroplasty (TKA), and a minimum of 5 years after TKA.

Methods

We enrolled patients who underwent TKA between 2013 and 2015 performed by a single arthroplasty surgeon at Siriraj Hospital, Mahidol University, Bangkok, Thailand. We evaluated PPTs and PROMs over a minimum 5-year follow-up period to assess changes over time, identified independent factors associated with PPT deterioration, and determined TKA survivorship.

Results

The study included 126 participants with a mean age of 77.8 years. The average follow-up time was 7.4 ± 2.3 years. PPTs and PROMs changed significantly over time from baseline. However, the 2-minute walk test and timed up-and-go test results slightly declined after 1 year but did not attain minimal clinically important differences, and PROMs were maintained and showed no clinically significant changes after 1 year. Hospitalizations owing to complex medical conditions or trauma were independently associated with PPT deterioration. There was a 98.8% survivorship rate at 7.6 years.

Conclusions

In an Asian population undergoing TKA, PPTs and PROMs are maintained within acceptable ranges for at least 5 years after primary TKA. Trauma or hospitalizations arising from complex medical conditions were found to be associated with functional decline. A combined evaluation of PPTs and PROMs is advocated for a comprehensive assessment of patients after TKA.
