Abstract
Creation of the femoral tunnel in anterior cruciate ligament (ACL) reconstruction via the anteromedial portal can reproducibly achieve femoral tunnel positioning at the center of the femoral ACL footprint. Anteromedial portal drilling requires knee hyperflexion, which is awkward to perform. Knee hyperflexion to 120° can easily be achieved in the figure-4 position for femoral tunnel drilling via the anteromedial portal. The leg is hyperflexed in the figure-4 position on a Mayo stand. The offset femoral guide, guidewire, and drill are placed at the femoral ACL footprint via the anteromedial portal to create the femoral tunnel.
