Participation in the NewKnee Study

Help us revolutionize the prevention, diagnosis, and treatment of knee problems through digital innovations. We are looking for participants from all backgrounds: whether completely healthy, with mild symptoms, or after knee surgery.

Scientific Background

The goal of this study is the development and validation of a digital "outcome score" using Artificial Intelligence (AI). Previously, medical decisions were often based on outdated, static X-rays or sporadic clinic visits. With NewKnee, we transform your smartphone into a mobile movement laboratory. We collect highly complex sensor data from your everyday life to analyze objective movement patterns. To detect deviations and risks early on, we urgently need data from healthy individuals as a reference ("normative values"). Only then can we make discrepancies between perceived symptoms and objective mobility visible.

With NewKnee, we use your smartphone's sensors to make your actual mobility and function in everyday life objectively measurable. This allows for a much more precise assessment of your health and recovery process.

Participation Requirements

Medical

  • ✓ Group A (Reference): You have completely healthy knees and want to help us define the "gold standard" for human movement.
  • ✓ Group B (Symptoms): You have occasional knee problems or already diagnosed osteoarthritis (gonarthrosis).
  • ✓ Group C (Therapy/Surgery): You are scheduled for a knee replacement (TKR) or have already received one.

Technical

  • ✓ Owning a modern smartphone (Android or iOS).
  • ✓ Basic confidence in using apps.

Your Journey Through the Study

1

Registration & Information

After downloading the app, the entire study briefing and consent process take place conveniently, securely, and digitally directly on your smartphone.

2

Smart Tracking in Everyday Life

The app accompanies you passively in the background. In addition, you will perform short movement tests (e.g., standing up from a chair) at set intervals, which only take a few minutes and objectively measure your joint function.

3

AI-based Data Analysis

Your anonymized data (wearable data & digital questionnaires) will be evaluated by our team at the TUM Klinikum rechts der Isar to develop precise predictive models for musculoskeletal health.

Your Benefits

  • Understand your own movement profile: Gain objective insights into your real mobility and joint function in everyday life.
  • Citizen Science for AI: Make a direct contribution to the development of cutting-edge medical AI at the university of excellence TUM - even as a healthy person!
  • Progress monitoring: Visualize your health or recovery process transparently and measurably (e.g., with symptoms or after surgery).
  • 100% Remote: No lab visits or additional travel to the clinic required.

Important Note

In accordance with the German Health Care Advertising Act (HWG), we point out that the NewKnee app is a research tool. No healing promises or guarantees of an improvement in health status are given. Participation is voluntary and can be ended at any time without giving reasons. The app is not a medical device within the meaning of the Medical Device Regulation (MDR).
