New sponge could replace tendon graft for ACL tears

NCT ID NCT02664545

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study compares a new device called BEAR to standard ACL reconstruction surgery. BEAR uses a special sponge placed between the torn ends of the ligament to help it heal back together, while standard surgery uses a tendon graft from elsewhere in the knee. The trial includes 100 people aged 14 to 35 with complete ACL tears. Researchers will measure knee function and stability over 10 years to see if the new method works as well as the current one.

What this could mean

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

Active substance
BEAR Scaffold (a sponge placed between torn ligament ends to help it heal)
What this could lead to
If it works, this could offer a way to repair a torn ACL without removing a tendon from elsewhere, potentially leading to faster recovery and less long-term knee problems.
What could go wrong
This is a relatively small, early-stage trial (100 people) comparing a new device to a well-established surgery. The new method may not be as effective or could have unexpected complications like re-tear or stiffness.
