Combined Single-Bundle Anterior Cruciate Ligament and Anterolateral Structure Reconstruction Through a Modified Single Femoral Tunnel.

Anterior cruciate ligament (ACL) injuries are among the most common sports injuries, and ACL reconstruction is an important treatment method. Residual rotational stability following isolated ACL reconstruction is the main reason for graft rupture and unsatisfactory results. Many researchers have shown that combined ACL and anterolateral structure (ALS) reconstruction could decrease rotational instability and graft rupture rate, as well as improve satisfaction. Various methods have been described to reconstruct the ACL and ALS jointly. However, previous methods still have disadvantages, such as undesirable tunnel convergence, complex maneuver, and insufficient graft filling in the tibial tunnel. Therefore, we present our technique for reconstruction of the ACL and ALS through a modified single femoral tunnel. We have obtained promising clinical outcomes with this technique.
