Summary

This study tests whether an AI-based smartphone app can improve recovery for 106 adults after hip or knee replacement or hip fracture surgery. Participants use the app for 12 weeks at home to get real-time feedback on their exercises, while a comparison group follows the same exercises using paper handouts. The goal is to see if the app leads to better walking ability and less pain than standard instructions.
