Arthroscopic view of the ACL remnant. (A) An ACL remnant bridging between the femur and the tibia viewed through the central AM portal, (B) A longitudinal slit is made in an ACL remnant using an 11 mm blade introduced through the central AM portal while viewing through the AL portal. This would allow visualization of the tips of the guide pins used as the first step of drilling of the tibial tunnels.
