Summary

This trial compares standard physical therapy alone versus standard therapy plus daily use of a home stretching device (Ermi Knee Extensionater) for people recovering from ACL reconstruction. Participants are aged 14 to 65 and have had a first-time ACL repair using a patellar tendon graft. The study measures how well the knee can straighten over time. The goal is to see if adding high-intensity stretching at home helps restore full knee extension faster.

What this could mean

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

Active substance
Ermi Knee Extensionater device
What this could lead to
If it works, this could point toward a more effective home-based rehab approach for regaining full knee motion after ACL surgery.
What could go wrong
This is an early-phase trial with only 58 participants, so results may not apply to everyone. The device requires daily commitment and may cause discomfort.
