Combined Double-Bundle Anterior Cruciate Ligament Reconstruction and Anterior Cruciate Ligament-Mimicking Anterolateral Structure Reconstruction

Abstract

The outcomes of double-bundle anterior cruciate ligament (ACL) reconstruction leave room for improvement. We hope to augment double-bundle ACL reconstruction with the reconstruction of an ACL-mimicking anterolateral structure (ALS). Thus, we would like to introduce a combined double-bundle ACL reconstruction and ACL-mimicking ALS reconstruction technique. The main indication for this technique is ACL injury with a high degree of pivot shift test, general laxity, or near critical value of the posterior tibial slope. The main steps in this technique include preparation of an isolated graft for the anteromedial bundle of the ACL and a combined graft for the posterolateral bundle of the ACL and ALS, creation of three tibial tunnels and two femoral tunnels, graft placement, and final graft fixation at an adjustable loop. We have obtained promising clinical outcomes with this technique and consider that this report will provide new options in ACL reconstruction.
