AI-based Rehabilitation for Hip and Knee Surgery Patients

South Korea106 participantsStarted 2026-03-09

Plain-language summary

This study aims to evaluate the efficacy and safety of an AI-based home rehabilitation application ("Exersite Rehab") for patients who have undergone hip or knee arthroplasty(Total Knee Arthroplasty (TKA), Total Hip Arthroplasty (THA) or hip fracture surgery). Following surgery, effective rehabilitation is crucial for functional recovery; however, many patients face barriers to consistent in-hospital exercise. This interventional study divides participants into two groups to compare outcomes. The experimental group will perform a 12-week home-based rehabilitation program guided by an AI application that provides real-time posture correction and monitoring. In contrast, the control group will perform the same exercise protocol using traditional printed educational brochures.The primary objective is to determine if the AI-based digital healthcare solution significantly improves physical function, measured by the Functional Ambulatory Category(FAC), compared to conventional methods. Secondary outcomes including pain levels(Visual Analog Scale (VAS)) and joint-specific functional scores (Knee Society Score (KSS), Harris Hip Score (HHS)) will also be assessed over the 12-week period.

Inclusion Criteria: * Adult patients aged 19 years or older. * Patients scheduled to undergo hip or knee arthroplasty at Gangnam Severance Hospital or affiliated hospitals of Chung-Ang University Medical Center (Chung-Ang University Hospital, Gwangmyeong Hospital, Hyundai Hospital). * Patients with a preoperative Functional Ambulatory Category (FAC) stage of 4 or 5 (For hip fracture cases, pre-fracture FAC stage will be considered). * Patients capable of downloading and using mobile applications on smart devices (smartphones or tablets) independently without researcher assistance. * Patients who fully understand the study's purpose and procedures and have voluntarily signed the informed consent form. Exclusion Criteria: * Individuals unable to perform exercises due to severe musculoskeletal pain. * Individuals with severe dizziness or poor vision that prevents them from following exercise videos provided by the digital treatment. * Individuals with visual impairment that causes difficulty in recognizing the monitor/device screen. * Individuals requiring long-term inpatient treatment due to unstable vital signs. * Individuals with partial or total lower-limb amputation due to trauma, disease, or congenital defects. * Individuals classified as vulnerable subjects (as defined by clinical research ethics guidelines). * Any other individuals deemed ineligible for participation at the discretion of the principal investigator.
