To examine the effects of lower extremity muscle strength training on knee function recovery and quality of life in patients who underwent total knee replacement.
Patients with knee osteoarthritis after surgery experience decreased knee function that impacts their quality of life. However, patients typically lack a long-term, home-based and continuous leg exercise training method and rarely have studies explored the effects of exercise training on knee function recovery and quality of life.
A experimental and longitudinal study design.
The simple randomised sampling (based on patients' admission priority order) was used to collect participant data. Outcome measurements included the Knee Injury and Osteoarthritis Outcome Score. Participants were randomised to receive and starting lower extremity muscle strength training before surgery (training group, n = 100) or to receive usual care (nontraining group, n = 100). Data were collected and followed up with the patients before surgery (T1) and at 2 weeks (T2), 1 month (T3), 2 months (T4) and 3 months (T5) after discharge.
The Knee Injury and Osteoarthritis Outcome Score subscale scores showed that both groups of patients experienced knee function and quality of life decreases 2 weeks after total knee replacement, but all subscale scores gradually increased from the first month to the third month after total knee replacement. Both groups and times were significantly different, but the training group's knee function and quality of life recovered earlier and better than the nontraining group does.
This study confirmed that lower extremity muscle strength training helps to improve quality of life and knee function in patients who undergo total knee replacement. Healthcare staff should include this training in presurgical nursing care and in patients' discharge plans as a continuous, daily rehabilitation activity at home.
When patients are diagnosed with knee osteoarthritis and undergo surgery, a presurgical exercise education and discussion of knee function rehabilitation should be part of standard care.
探讨下肢肌肉力量训练对全膝关节置换术后膝关节功能恢复和生活质量的影响。
膝关节骨关节炎患者术后膝关节功能下降，影响其生活质量。然而，患者通常缺乏长期、家庭为基础且持续的腿部运动训练方法，很少有研究探讨运动训练对膝关节功能恢复和生活质量的影响。
实验性、纵向研究设计。
采用单纯随机抽样（根据患者入院的优先顺序）收集参与者数据。结局测量包括膝关节损伤和骨关节炎结果评分。参与者被随机分为接受术前下肢肌肉力量训练组（训练组，n=100）或接受常规护理组（非训练组，n=100）。在术前（T1）和术后 2 周（T2）、1 个月（T3）、2 个月（T4）和 3 个月（T5）收集和随访患者的数据。
膝关节损伤和骨关节炎结果评分亚量表评分显示，两组患者在全膝关节置换术后 2 周内均出现膝关节功能和生活质量下降，但所有亚量表评分从全膝关节置换术后第一个月开始逐渐升高，直到第三个月。两组和时间均有显著差异，但训练组的膝关节功能和生活质量恢复较早且优于非训练组。
本研究证实，下肢肌肉力量训练有助于改善全膝关节置换术后患者的生活质量和膝关节功能。医护人员应将这种训练纳入术前护理和患者出院计划中，作为家庭中持续的日常康复活动。
当患者被诊断为膝关节骨关节炎并接受手术时，术前运动教育和膝关节功能康复讨论应成为标准护理的一部分。
