Optimizing graft selection for ACL reconstruction

Optimizing GRAft SElection for ACL Reconstruction (GRASE-ACL Trial) - a Three-armed Randomized Controlled Trial

Not applicable Interventional Hvidovre University Hospital · NCT05342441

This study is testing which type of graft—quadriceps tendon, hamstring tendons, or patellar tendon—works best for helping young adults recover from their first ACL injury.

What this trial studies

This clinical trial investigates the differences between three common methods for anterior cruciate ligament (ACL) reconstruction: using grafts from the quadriceps tendon, hamstring tendons, or patellar tendon. The study aims to provide a patient-centered and biomechanical perspective on how graft choice affects knee function, muscle strength, and overall surgical outcomes. By employing a randomized controlled design, 150 patients aged 18-40 with first-time ACL ruptures will be followed to assess the effectiveness of each graft type. The goal is to develop evidence-based, individualized treatment options for ACL injuries.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18-40 with a clinically confirmed first-time ACL rupture and a high activity level prior to injury.

Not a fit: Patients with prior knee surgeries, significant osteoarthritis, or other medical conditions that prevent full participation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and personalized treatment strategies for patients undergoing ACL reconstruction.

How similar studies have performed: Other studies have explored graft selection in ACL reconstruction, but this trial's comprehensive approach is relatively novel.
