The knee range of motion is an important outcome of total knee arthroplasty (TKA). According to previous studies, the knee range of motion temporarily decreases for approximately 1 month after TKA due to postoperative pain and quadriceps dysfunction following surgical invasion into the knee extensor mechanism. We describe our experience with a knee-extension training program based on a single-joint hybrid assistive limb (HAL-SJ, Cyberdyne Inc., Tsukuba, Japan) during the acute recovery phase after TKA. HAL-SJ is a wearable robot suit that facilitates the voluntary control of knee joint motion. A 76-year-old man underwent HAL-SJ-based knee-extension training, which enabled him to perform knee function training during the acute phase after TKA without causing increased pain. Thus, he regained the ability to fully extend his knee postoperatively. HAL-SJ-based knee-extension training can be used as a novel post-TKA rehabilitation modality.
膝关节活动范围是全膝关节置换术(TKA)的一项重要疗效指标。根据以往研究,TKA术后由于手术侵入膝关节伸肌机制导致术后疼痛和股四头肌功能障碍,膝关节活动范围会暂时减小约1个月。我们描述了在TKA术后急性康复阶段基于单关节混合辅助肢体(HAL-SJ,日本筑波赛博 Dyn公司)进行伸膝训练计划的经验。HAL-SJ是一种可穿戴机器人套装,有助于膝关节运动的自主控制。一名76岁男性接受了基于HAL-SJ的伸膝训练,这使他能够在TKA术后急性期进行膝关节功能训练而不会导致疼痛加剧。因此,他术后恢复了膝关节完全伸直的能力。基于HAL-SJ的伸膝训练可作为一种新型的TKA术后康复方式。
