Summary

This study tests a wearable device called TracPatch that sticks to the shin after total knee replacement surgery. The patch tracks knee motion, temperature, and steps for six weeks, sending data to doctors. Researchers want to see if this real-time monitoring helps patients regain movement and improves communication with their surgeon. About 150 adults having knee replacement are taking part.

What this could mean

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

Active substance
Consensus TracPatch wearable device
What this could lead to
If it works, this could give surgeons and patients real-time data to improve recovery after knee replacement.
What could go wrong
This is a small, early-stage study with no blinding. The device may not meaningfully improve outcomes over standard care.
