Abstract
Aim: The lateral intercondylar ridge (LIR) represents the main bony landmark for determining the ACL femoral footprint and for placing the tunnel in the center of the native femoral footprint below the LIR. This study aimed to describe the relationship between the LIR and the intact femoral insertion of the anterior cruciate ligament. Materials and Methods: Ten fresh-frozen, cadaveric knee specimens were obtained for this study. The medial femoral condyle was removed with the aim of finding any protrusion or ridge on the medial wall of the lateral femoral condyle. The exposed areas were carefully analyzed, visually and by palpation. Analyses were performed with ACL stump and after removing the whole ACL from the femoral insertion. Results: In 70% of specimens the ridge was not visible while the ligament was attached to its femoral insertion. In 20% of specimens the ridge was observed outside the fibrous insertion, but only above posterolateral bundle. After removing all ligament fibers in one specimen we could not find bone ridge. Conclusion: In 90% of specimens the LIR was an integral part of the femoral insertion. This observation must be taken into account during ACL reconstructive surgery.
