To compare the habitual sedentary behavior (SB) and physical activity (PA) of older hip osteoarthritis patients before and after elective arthroplasty. SB, PA and joint-specific disability of 16 patients (68.9 ± 6.8 years) were assessed by accelerometry and questionnaires before and 9 months after arthroplasty. All patients reported substantial postoperative improvements of their joint-related complaints ( ≤ 0.001). Accelerometry showed changes in neither daily SB (10-60 min sedentary bouts, ≥ 0.569) nor in PA (steps, time in mild-to-vigorous activity and energy expenditure, ≥ 0.255). Correlation analyses revealed that patients with severe preoperative disability showed a decrease in sedentary time, which was the opposite in patients with mild preoperative disability. SB and PA do not necessarily change after arthroplasty in older orthopedic patients. Even longer bouts of uninterrupted sitting, which are detrimental to health, do not decrease. Preoperative patient education is recommended to foster behavioral changes following elective arthroplasty.
比较择期关节置换术前、后老年髋骨关节炎患者的习惯性久坐行为（SB）和身体活动（PA）情况。通过加速度计和问卷调查对16例患者（68.9±6.8岁）在关节置换术前及术后9个月时的SB、PA和关节特异性残疾情况进行评估。所有患者均报告术后关节相关症状有显著改善（≤0.001）。加速度计显示，每日SB（久坐时长10 - 60分钟，≥0.569）和PA（步数、轻度至剧烈活动时间及能量消耗，≥0.255）均无变化。相关性分析显示，术前残疾严重的患者久坐时间减少，而术前残疾轻度的患者情况则相反。老年骨科患者关节置换术后SB和PA不一定会改变。即使是对健康有害的更长时间的不间断坐姿也没有减少。建议术前对患者进行教育，以促进择期关节置换术后的行为改变。
