Summary

This trial compares two methods for fixing a tendon graft during ACL knee surgery: a newer button system (Endobutton CL BTB) versus standard metal screws. About 220 people having their first ACL reconstruction will be randomly assigned to one method. The study tracks knee function, stability, strength, and bone healing over time to see which approach works better.

What this could mean

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

Active substance: a device for fixing a tendon graft in ACL reconstruction: either the Endobutton CL BTB system or a metal interference screw
What this could lead to: If the Endobutton proves better, it could become the preferred method for ACL graft fixation, potentially improving recovery and reducing complications.
What could go wrong: This is a single-center trial, and the newer method may not show clear advantages over the standard screw. Bone healing with the Endobutton is still unconfirmed.
