N2 - Anatomic double-bundle anterior cruciate ligament (ACL) reconstruction can restore the function and kinematics of the knee in ACL-deficient patients. Several outside-in drilling systems for accurate femoral tunnel creations have been developed. However, the femoral tunnel creation at the lower position of the intercondylar notch can be difficult in a usual leg position with the knee flexed at 90° without varus stress. This technical note describes that the figure-of-nine leg position provides a better arthroscopic view to safely clean up the ACL femoral footprint located at the lower area of the lateral intercondylar wall. This position is useful to create the optimal femoral tunnels using the outside-in drilling technique, without damaging the lateral meniscus posterior root, lateral tibial eminence, and supplemental fibers that bridge the gap between the lateral meniscus and the ACL tibial insertion.
