Surgical Adjustment of the Guide Pin to Perform a Correct Tibial Tunnel in Anatomical Anterior Cruciate Ligament Single-Bundle Reconstruction
Anatomical positioning of the graft in anterior cruciate ligament reconstruction is important to restore normal knee kinematics and prevent early joint degeneration. Inadequate position of a first attempt to place the guide pin within the center of the tibial footprint may occur. Therefore, its adju...

description |
Anatomical positioning of the graft in anterior cruciate ligament reconstruction is important to restore normal knee kinematics and prevent early joint degeneration. Inadequate position of a first attempt to place the guide pin within the center of the tibial footprint may occur. Therefore, its adjustment is important to achieve the anatomical positioning of the graft within the tibial footprint. When the guide pin exits eccentrically in an inadequate position, it is possible to correct it to the center of the footprint. A small tunnel with a 4.5-mm reamer is made and the guide pin is shifted to the center of the footprint. The center of the tunnel can be corrected until 50% and in all direction in relation to the initial drilled tunnel, without additional associated morbidity. Once the correct position of the center is achieved, the guide pin is fixed in the femoral notch roof to guarantee the accurate correction of the axis, without toggling of the guide pin inside the tunnel and metal dusting. The final tunnel is then drilled with the same size of the graft. With this technique it is possible to adjust an eccentrically misplaced guide pin to the center of the footprint without additional morbidity. |
