Interventions

  • Exersite Rehab (AI-based Mobile Application) — DEVICE
    The "Exersite Rehab" is an AI-driven digital healthcare solution designed for post-operative rehabilitation. It utilizes computer vision technology to track the patient's skeletal movements in real-time through a smartphone camera. During the 12-week program, the device provides personalized exercise protocols, real-time posture correction, and automatic repetition counting to ensure safe and effective home-based rehabilitation for patients after hip or knee surgery.
  • Printed Educational Brochure (Traditional Rehabilitation) — BEHAVIORAL
    Participants in the control group will receive traditional printed educational brochures containing standardized post-operative exercise protocols for hip or knee surgery. These brochures include step-by-step illustrations and written instructions for home-based rehabilitation exercises. Participants are instructed to perform the prescribed exercises independently for 12 weeks, following the same schedule and frequency as the experimental group, but without the AI-based real-time feedback or digital monitoring.

Study Details

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.

Arms

  • Experimental: Experimental Group (AI App)
    Participants in this group will perform a 12-week home rehabilitation program using the "Exercite Rehab" AI-based mobile application, which provides real-time motion tracking and feedback.
  • Active Comparator: Control Group (Brochure)
    Participants in this group will perform the same 12-week rehabilitation exercise protocol using traditional printed educational brochures.
