To retrospectively investigate the effects of motor imagery (MI) training in enhancing knee joint function after unicompartmental knee arthroplasty (UKA).
This study included 84 patients who underwent UKA at the Orthopedic Joint Department of Shangluo Central Hospital between January 2023 and October 2024. Patients were divided into an experimental group (n = 42) receiving MI training and a control group (n = 42) receiving standard rehabilitation. Clinical outcomes were assessed using the Oxford Knee Score (OKS), Visual Analogue Scale (VAS), range of motion (ROM), Timed Up and Go Test (TUGT), Berg Balance Scale (BBS), and Hospital for Special Surgery Knee Score (HSS) at 1, 6, and 12 months postoperatively. Imaging parameters were also analyzed at 6 months.
Compared to the control group, the experimental group exhibited significantly better clinical outcomes across all measured functions (OKS, VAS, ROM, TUGT, HSS, BBS, Knee flexion angle) at 1, 6, and 12 months postoperatively (all P < 0.01). Specifically, both groups showed significant OKS improvement and VAS reduction post-surgery. The experimental group had more pronounced OKS enhancement and VAS decrease than the control group, especially at 6 and 12 months (all P < 0.001). ROM, HSS, and BBS scores and knee flexion angle progressively increased over time in both groups (all P < 0.05), with the experimental group having higher values at all follow-up times (all P < 0.01). TUGT times were significantly reduced in both groups postoperatively, with greater reduction in the experimental group than the controls at each time point (P < 0.01).
Motor imagery training, when combined with standard postoperative care, significantly enhances knee joint recovery following UKA, reduces patient discomfort, and accelerates functional rehabilitation.
回顾性研究运动想象（MI）训练对单髁膝关节置换术（UKA）后膝关节功能恢复的影响。
本研究纳入了2023年1月至2024年10月在商洛市中心医院骨科关节科接受UKA手术的84例患者。将患者分为接受MI训练的实验组（n = 42）和接受标准康复治疗的对照组（n = 42）。在术后1、6和12个月，使用牛津膝关节评分（OKS）、视觉模拟评分（VAS）、活动范围（ROM）、计时起立行走测试（TUGT）、伯格平衡量表（BBS）和特殊外科医院膝关节评分（HSS）评估临床疗效。在术后6个月还分析了影像学参数。
与对照组相比，实验组在术后1、6和12个月的所有测量功能（OKS、VAS、ROM、TUGT、HSS、BBS、膝关节屈曲角度）方面均表现出明显更好的临床疗效（所有P < 0.01）。具体而言，两组术后OKS均显著改善，VAS均降低。实验组的OKS改善和VAS降低比对照组更明显，尤其是在6个月和12个月时（所有P < 0.001）。两组的ROM、HSS和BBS评分以及膝关节屈曲角度均随时间逐渐增加（所有P < 0.05），实验组在所有随访时间的值均更高（所有P < 0.01）。两组术后TUGT时间均显著缩短，实验组在每个时间点的缩短幅度均大于对照组（P < 0.01）。
运动想象训练与标准术后护理相结合，可显著促进UKA术后膝关节恢复，减轻患者不适，并加速功能康复。
