Summary

This study tests whether an AI-based exercise app (Kemtai) can help people recover faster after total knee replacement surgery. The app tracks your movements and gives real-time feedback, unlike the standard paper handout. Researchers will measure how long people stay in the hospital and how many physiotherapy visits they need. The study involves 40 adults scheduled for knee replacement at two UK hospitals.

What this could mean

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

Active substance: Kemtai digital app (AI-based motion tracking exercise programme)
What this could lead to: If it works, this could help people recover faster after knee replacement surgery with less need for in-person physiotherapy.
What could go wrong: This is a small feasibility study with only 40 participants, so results may not apply to everyone. The app requires a compatible device and internet access, which could limit use.
