"Figure 8" single socket double bundle ACL technique

Using single femoral and tibial tunnels, we describe a technique of anatomically recreating the anteromedial and posterolateral anterior cruciate ligament (ACL) bundles. Transtibial, flexible reamers are utilized to create a "Figure 8" notched tunnel thereby recreating the anatomic footprint of the femoral insertion of the ACL. Rotational control of the individual bundles is created via the notched tunnel and each bundle is tensioned to 80 N individually. Anatomic double bundle ACL reconstruction is created in a reproducible modified single-bundle technique without the inherent risks associated with drilling four tunnels.
