Importance of longitudinal slit in the ACL remnant and angles of the tibial tunnels. Schematic drawing showing the importance of making a longitudinal slit in the ACL remnant which together with a more vertical orientation of the tibial tunnels with an angle of 65°. (A) Better visualization of the tip of the guide wires during creation of the AM and PL tibial tunnels through the anatomical ACL tibial footprint. (B) Without the longitudinal slit, and with the ACL tibial guide adjusted to 45°, it would be impossible to visualize the tips of the guide wires used for preliminary drilling of the tibial tunnels as in that case they will be parallel to the preserved ACL remnant.
