Summary

This pilot study tests a smartphone app that collects movement data and patient questionnaires to create a score that predicts satisfaction after knee or hip replacement. Researchers will enroll 1,250 people, including patients before or after surgery and healthy volunteers. The goal is to identify who might be unhappy with their results and improve care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: KneeApp (smartphone app for data collection and functional tests)
What this could lead to: If successful, this could lead to a tool that helps doctors predict which patients may be unhappy after joint replacement, allowing earlier support.
What could go wrong: This is a small, early pilot study. The app is only in German and requires a smartphone, so results may not apply to everyone. The score is not yet proven to work.
