Summary

This study looked at 120 people who had surgery to repair a torn anterior cruciate ligament (ACL) in the knee. The surgeons either preserved the remaining stump of the torn ligament or removed it before placing a new graft. The goal was to see which approach led to better knee stability, function, and sense of joint position. The results could help guide surgical choices for ACL injuries.

What this could mean

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

Active substance
ACL reconstruction (procedure using hamstring tendon graft)
What this could lead to
If preserving the stump works better, it could lead to improved surgical techniques for ACL tears, potentially giving patients better knee stability and function.
What could go wrong
This is a completed study with 120 patients, but it is not a large or long-term trial. The results may not apply to all types of ACL injuries or to patients with other knee problems.
