ACL with tunnel too anterior ACL with tunnel repositioned
This left X-ray shows the joint where the ACL graft failed because the tunnels were too anterior. Take a look at the femur (top bone). The white bits are the fixation devices holding the graft in the tunnel. The right X-ray shows the original tunnel (yellow arrow) with the new tunnel behind it and in the correct position. You get an idea of how far anterior the original tunnel was made. If you cannot orientate, look for the patella bone - that is the anterior aspect.
