A Study to Compare Two Techniques for the Reconstruction of the Anterior Cruciate Ligament

A Randomized Controlled Trial to Evaluate the Graft Ligamentization and Integration in the Reconstruction of the Anterior Cruciate Ligament With or Without Detachment of Hamstring Tendon Tibial Insertion

This is a prospective and randomized trial to compare two different techniques used in normal practice for the reconstruction of the anterior cruciate ligament in arthroscopy.

The experimental group (group 1) will undergo a reconstruction technique where semitendinosus and gracilis will preserve their insertion at the level of the hamstring whereas in the control group (group 2) the semitendinosus and gracilis tendons will be disengaged from their insertion on the hamstring .
