The aim of the current study was to evaluate the effects of a nurse-led hybrid teaching program on lower limb strength, knee function, and depression in older adults after total knee replacement (TKR). This was a single-blind, randomized controlled trial. Fifty-two patients who underwent TKR were randomly assigned to either the experimental group (EG; n = 26), which received routine care plus 16 weeks of home rehabilitation through a hybrid teaching program, or the control group (CG; n = 26), which received routine care only. The intervention included pre-discharge face-to-face education, video instructions to follow at home after discharge, and four monthly telephone-based follow ups during the 16 weeks post-surgery. After the 16-week intervention, participants in the EG exhibited improved quadriceps strength, hamstring strength, and Knee Injury and Osteoarthritis Outcome Score (KOOS) compared to those in the CG. Generalized estimating equation analyses revealed a significant group-by-time interaction effect on quadriceps strength, overall KOOS score, and Geriatric Depression Scale-Short Form score. Findings suggest that a nurse-led hybrid teaching program enhances physical and psychological function after TKR when compared to routine care. This hybrid teaching program, involving exercise and postoperative education, proves to be a feasible and cost-effective intervention for improving outcomes in older adults following TKR. Health care teams should consider it as a viable home rehabilitation option for older adults who undergo TKR. [Research in Gerontological Nursing, xx(x), xx-xx.].

混合教学计划对全膝关节置换术后老年人下肢肌肉力量、膝关节功能和抑郁的影响：随机对照试验。

本研究的目的是评估护士主导的混合教学计划对全膝关节置换术（TKR）后老年人下肢力量、膝关节功能和抑郁的影响。这是一项单盲、随机对照试验。接受 TKR 的 52 名患者被随机分配到实验组（EG；n = 26）和对照组（CG；n = 26），实验组接受常规护理加上通过混合教学计划进行 16 周的家庭康复。 ，仅接受常规护理。干预措施包括出院前面对面教育、出院后在家遵循的视频说明以及术后 16 周内每月进行四次电话随访。经过 16 周的干预后，与 CG 参与者相比，EG 参与者的股四头肌力量、腿筋力量以及膝关节损伤和骨关节炎结果评分 (KOOS) 有所改善。广义估计方程分析显示，按时间分组对股四头肌力量、总体 KOOS 评分和老年抑郁量表简式评分有显着的交互作用。研究结果表明，与常规护理相比，护士主导的混合教学计划可以增强 TKR 后的身体和心理功能。这种涉及运动和术后教育的混合教学计划被证明是一种可行且具有成本效益的干预措施，可改善老年人 TKR 后的预后。医疗保健团队应将其视为接受 TKR 的老年人的可行家庭康复选择。[老年护理研究，xx(x)，xx-xx.]。
