64 young men with an anterior cruciate ligament (ACL) injury were randomized to undergo reconstruction with either the transtibial (TT) or anteromedial portal (AMP) technique for femoral tunnel placement. The purpose of the study was twofold: First, to determine the tunnel placement and clinical outcome associated with each procedure, and second, if there was a significant difference in outcome between them. Results after a minimum of 2-year follow-up indicated a more posterior placement of the femoral tunnel aperture and greater stability in knees reconstructed with the AMP technique.
