Rehabilitation Exercise Using Digital Healthcare System in Patients With Anterior Cruciate Ligament Reconstruction

Anterior cruciate ligament(ACL) is a vital structure in the knee maintaining the stability and due to increased population engaging in sports activities, the ACL injury is becoming more prevalent among young adults. Rehabilitation after ACL reconstruction is essential to restore knee function and many factors including age, degree of sports activities engagement, weight bearing should be considered when organizing rehabilitation programs. Knee joint stiffness and weakness of knee flexor/extensor muscles are common problems following the surgery which are related to improper rehabilitation after ACL reconstructions. Current method of post-operative rehabilitation is home-based self rehabilitation using brochure, combined with one or two times of education at the hospital before discharge. Patients often find difficulty in doing rehabilitation by themselves at home without supervision which resulted in decreased compliance. With development of technologies using multi-motion sensor and AR(augmented-reality) system, the investigators have developed a digital healthcare system(Uincare Homeplus) which can supplement patients' rehabilitation at home by giving them proper instructions as well as feedback. In this prospective randomized controlled study, the investigators aim to compare the efficacy of the newlydeveloped digital healthcare system with conventional rehabilitation program.
