The curved guide system allows a certain degree of control over intra-articular tunnel orientation regardless of the knee flexion angle due to the rotational freedom of the guide in the intercondylar notch space. This is contrary to tunneling with a straight guide pin, which has fixed intra-articular tunnel orientation from two points, the AM or AAM portal and the femoral tunnel center
