Comparison of the Efficacy of Telerehabilitation and In-person Rehabilitation Based on Wearable Devices After ACLR Surgery: a Multicenter Randomized Controlled Trial

Purpose: Investigate whether telerehabilitation based on wearable devices is clinically as effective as in-person rehabilitation for ACLR patients. Subjects: 164 patients aged ≥18 years who underwent ACLR. Design: A mixed-block randomization method was used to randomly assign participants to two groups: the telerehabilitation group and the in-person rehabilitation group, with a 50% probability of assignment to each group. All participants received standard postoperative rehabilitation training with identical content. The telerehabilitation group received postoperative telerehabilitation guidance via software and sensors. The in-person rehabilitation group received therapist-administered treatment with three rehabilitation sessions per week. All participants underwent regular follow-ups (1 day preoperatively, 3 months postoperatively, and 6 months postoperatively). Primary outcome measure: The primary outcome measure was the Lysholm score. Secondary outcome measures included the IKDC score, Tegner Activity Scale, SF-36 questionnaire, VAS score, and isokinetic muscle strength of the knee joint.
