Development of an Outcome Score for Patients With Knee Osteoarthritis and Knee Joint Endoprosthesis Using an App
This trial is testing a smartphone app called KneeApp that tracks movement, gait, and self-reported outcomes in people before and after knee or hip replacement surgery. The goal is to build a scoring tool — trained with machine learning — that predicts how satisfied a patient will be after joint replacement. This is a pilot study, meaning it is exploratory and data-gathering, not testing a treatment. Details beyond the app and satisfaction measurement are limited.
