The aim of the present study was to investigate the effect size (ES) of total knee arthroplasty (TKA) for the symptoms and lower limb function and identify preoperative factor(s) associated with the post-operative activity of daily living (ADL) in aged patients with end-stage knee OA undergoing TKA.
Fifty-nine aged patients with end-stage knee OA (mean age: 74.6 years) were enrolled in this study. The symptoms and lower limb function of the patients were evaluated using the Japanese Knee Osteoarthritis Measure (JKOM), the timed up and go (TUG) test and timed single-legged stance test with eyes open (TSLS) before and after six months from the operation.
While the ES of TKA for the improvement of pain was 2.83, the ES of TKA for the improvement of ADL, TUG and TSLS were 1.30, 0.59, and 0.49, respectively. While the post-operative ADL score was not associated with the preoperative ADL or pain scores, it was associated with the preoperative TUG and TSLS scores. A multiple regression analysis revealed that the one preoperative factor associated with the postoperative ADL was the TSLS.
The preoperative TSLS is associated with the postoperative ADL in aged disabled patients with end-stage knee OA.
本研究旨在调查全膝关节置换术（TKA）对症状和下肢功能的效应量（ES），并确定接受TKA的终末期膝骨关节炎老年患者术后日常生活活动（ADL）的术前相关因素。
本研究纳入了59例终末期膝骨关节炎老年患者（平均年龄：74.6岁）。在手术前及术后6个月，使用日本膝关节骨关节炎量表（JKOM）、计时起立行走（TUG）测试和睁眼计时单腿站立测试（TSLS）对患者的症状和下肢功能进行评估。
TKA改善疼痛的ES为2.83，TKA改善ADL、TUG和TSLS的ES分别为1.30、0.59和0.49。术后ADL评分与术前ADL或疼痛评分无关，但与术前TUG和TSLS评分相关。多元回归分析显示，与术后ADL相关的术前因素之一是TSLS。
术前TSLS与终末期膝骨关节炎老年残疾患者的术后ADL相关。
