The functional relevance of the two anatomic bundles of the anterior cruciate ligament (ACL) is accounted for when using the anatomical double-bundle reconstruction of the ACL. In this study graft positions within the anatomical footprints of the ACL were examined at seven fresh-frozen human knees. By using a testing device that was especially developed for this study, the knee could be fixed in different positions of flexion; all these positions could be exactly reproduced. The intra-articular change in distance of any possible graft positions could be examined using a wire. Regarding both bundles, the change in distance during a physiological flexion of the knee was minimal when the femoral drill hole position was situated in the antero-superior site of the anatomical femoral insertion. For the tibial graft position of both bundles, a medial drill hole located within the anatomical footprint led to a minimal change in distance.
