Effects of Supplemental Robot-Assisted Knee Flexion Exercise After Total Knee Arthroplasty: A Randomized Controlled Clinical Study.
Objectives: This study aimed to investigate the beneficial effects of single-joint hybrid assistive limb (HAL-SJ)-assisted rehabilitation after total knee arthroplasty (TKA), with a focus on the early postoperative period.
Methods: This single-anonymized randomized controlled trial assigned 72 participants who underwent primary TKA for knee osteoarthritis to the HAL-SJ (n=35) and control groups (n=37). The passive knee range of motion (ROM; i.e., the primary outcome) was evaluated preoperatively and at 1 week, 2 weeks, and 3 months postoperatively. Extension lag and knee pain intensity scores were evaluated preoperatively and at 1 and 2 weeks postoperatively. Quadriceps and hamstring isometric knee strength and walking speed were evaluated preoperatively and at 2 weeks postoperatively. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was evaluated preoperatively and at 3 months postoperatively.
Results: Compared with the control group, the HAL-SJ group showed significantly improved knee extension ROM (p=0.001) and greater KOOS Activities of Daily Living subscale score (p=0.005) at 3 months postoperatively, with a significantly early improvement in extension lag (p=0.001) and hamstring strength (p=0.012) at 2 weeks postoperatively.
Conclusions: HAL-SJ effectively supports postoperative rehabilitation, showing clinical advantages for improving daily activities by 3 months after TKA.
Clinical trial registration: University Hospital Medical Information Network (UMIN000053675).
期刊介绍：
The Journal of Musculoskeletal and Neuronal Interactions (JMNI) is an academic journal dealing with the pathophysiology and treatment of musculoskeletal disorders. It is published quarterly (months of issue March, June, September, December). Its purpose is to publish original, peer-reviewed papers of research and clinical experience in all areas of the musculoskeletal system and its interactions with the nervous system, especially metabolic bone diseases, with particular emphasis on osteoporosis. Additionally, JMNI publishes the Abstracts from the biannual meetings of the International Society of Musculoskeletal and Neuronal Interactions, and hosts Abstracts of other meetings on topics related to the aims and scope of JMNI.
