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.

Detailed description

* Study Overview and Randomization This study is conducted as a multi-center, randomized, open-label trial. After providing informed consent and completing baseline assessments, eligible participants are randomly assigned to either the Experimental Group or the Control Group at a 1:1 ratio. The primary focus is to evaluate the recovery of physical mobility through different home-based rehabilitation methods. * Technical Intervention Protocols The Experimental Group utilizes the "Exercite Rehab" mobile application, which incorporates AI-based computer vision technology. The application recognizes the participant's joint movements in real-time through the device's camera, providing immediate corrective feedback on exercise posture and automatically logging the completion of prescribed routines. In contrast, the Control Group follows the same clinical exercise protocol using traditional printed educational materials. Participants in this group manually record their daily exercise performance in a provided physical logbook. * Longitudinal Monitoring and Follow-up Following the initial in-hospital education session, participants transition to a 12-week home-based phase. Research personnel conduct remote monitoring at specific intervals (Weeks 4 and 8) to ensure safety, assess exercise adherence, and track symptomatic changes via telephone or the application's monitoring dashboard. A final face-to-face clinical evaluation is performed at Week 12 to determine the overall efficacy of the intervention compared to the conventional method.

Interventions

Type	Name	Description
DEVICE	Exersite Rehab (AI-based Mobile Application)	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.
BEHAVIORAL	Printed Educational Brochure (Traditional Rehabilitation)	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.
