Abstract
We used a laser beam to determine the location of the femoral tunnel during ACL reconstruction. Location of the correct anatomical site is necessary in order to perform intra-articular drilling in the tibia. With this technique, a laser pointer is set at the tibial guide, which reflects the laser beam and illuminates the point where the femoral bone tunnel should be made. This is the first report of the use of a laser-guided technique for arthroscopic surgery.
Using postoperative 3D-CT, we evaluated double-bundle ACL reconstruction of 38 joints in terms of the location of the bone tunnel in the femur and tibia, and examined antero-posterior instability with a KT-1000 before and after the operation. It was possible to create the bone tunnel at the correct anatomical site of the AMB and PLB in both the femur and tibia. Our method is useful for creation of a bone tunnel at the correct anatomical site of the ACL.
