Reconstruction of the ACL With QT Graft With Bone Plug vs BPTB

ClinConnect Summary

This clinical trial is investigating two different methods for repairing a torn anterior cruciate ligament (ACL), which is a common injury, especially among athletes. The trial compares the traditional bone-patellar tendon-bone (BPTB) graft technique with a newer option called the quadriceps tendon (QT) graft. Researchers want to see which method provides better results in terms of knee function and if there are any complications after surgery.

To participate in this study, you need to be between 15 and 55 years old and have a confirmed ACL tear diagnosed by an MRI. Certain health conditions, like diabetes or previous knee surgeries, might disqualify you from joining. If you do take part, you'll undergo surgery where you'll be randomly assigned to one of the two graft types. Over the next two years, your knee will be evaluated at regular intervals to measure its stability and your recovery. This trial is an opportunity to help improve ACL repair techniques, benefiting future patients.
