The Quad 2.0 Technique: A Single Rectus Femoris Tendon Autograft Solution for Combined Anterior Cruciate Ligament and Double-Bundle Anterolateral Ligament Reconstruction.

Rectus femoris tendon autograft is gaining popularity for anterior cruciate ligament (ACL) reconstruction as the result of advancements in harvesting techniques that minimize soft-tissue dissection and reduce donor-site morbidity. In this Technical Note, we describe a surgical technique for ACL and anterolateral ligament reconstruction in revision ACL cases using a single rectus femoris autograft, with a focus on the harvesting technique to ensure adequate graft length and diameter. Notably, anterolateral ligament fixation is performed without the need for additional femoral or tibial tunnels.
