We examined the arthroscopic appearance of the anterior cruciate ligament (ACL) attachment site on the femur in five fresh-frozen cadaver knees. First, the ACL was cut out, leaving a footprint of ligament-fibers with a length of 2 mm intact. The ACL was consistently found to insert on the lateral wall of the notch. No fibers were found to attach high in the roof of the notch at the 12 o'clock position. Secondly, we tried to reach the anatomical attachment site with a femoral aiming guide through a correctly placed tibial tunnel. This proved to be impossible. The closest position that could be reached was at the margin of the anatomical attachment site. Investigation of the distal femur after complete dissection confirmed these arthroscopic findings. Femoral aiming devices for use through the tibial tunnel aim for an isometric placement of the femoral tunnel, they do not aim for an anatomical position of the graft.
我们检查了5个新鲜冷冻尸体膝关节中前交叉韧带（ACL）在股骨上附着点的关节镜下表现。首先，切除ACL，保留长度为2毫米的韧带纤维足迹。始终发现ACL附着于髁间窝的外侧壁。在髁间窝顶部12点位置高处未发现纤维附着。其次，我们试图通过正确放置的胫骨隧道用股骨瞄准器到达解剖学附着点。结果证明这是不可能的。能够到达的最接近位置是解剖学附着点的边缘。完全解剖后对股骨远端的研究证实了这些关节镜检查结果。通过胫骨隧道使用的股骨瞄准装置旨在使股骨隧道等距放置，而不是使移植物处于解剖学位置。
