INTRODUCTION: Total Knee Arthroplasty (TKA) is widely performed for severe knee osteoarthritis, and postoperative rehabilitation plays a key role in optimizing functional recovery. This study compares the efficacy of conventional physiotherapy, virtual rehabilitation, and home-based telerehabilitation following TKA. METHODS: A randomized controlled trial involving 120 patients was conducted. Participants were randomly assigned to one of three rehabilitation protocols. Outcomes were measured using the Knee Injury and Osteoarthritis Outcome Score (KOOS), range of motion (ROM), and Visual Analog Scale (VAS) for pain at 3 and 6 months postoperatively. Statistical analysis was performed using ANOVA (p < 0.05). RESULTS: Virtual rehabilitation showed significantly better KOOS and ROM outcomes at both follow-up points (p < 0.01), while home-based telerehabilitation demonstrated greater pain relief at 6 months (p = 0.03). CONCLUSIONS: Virtual rehabilitation led to superior functional improvements, while home-based telerehabilitation effectively reduced the pain. These findings suggest that incorporating technology into rehabilitation enhances recovery post-TKA.
