A Novel Graft Preparation Technique of the Quadriceps Tendon for Arthroscopic Double-Bundle Anterior Cruciate Ligament Reconstruction

摘要

Surgical reconstruction is a general approach for an anterior cruciate ligament rupture. Techniques have evolved from single-bundle to double-bundle reconstruction to restore the 2 anatomically and functionally different bundles as much as possible. However, there is controversy regarding which method yields superior clinical outcomes. The purpose of this article is to introduce our new graft preparation method, which will potentially address the limitations of currently available double-bundle anterior cruciate ligament reconstruction procedures using the quadriceps tendon. The proximal portion of the graft is preserved in our method, instead of completely being split into 2 distinct graft bundles as previously suggested. We believe that the preserved portion can act as a biofunctional “safety circuit” in case of overloading and also help some synergistic actions of the 2 bundles.
