- Abstract
While ACL reconstruction using single-tunnel and single-bundle techniques generally yields good clinical results, more and more studies are now reporting results that are not entirely satisfactory, as this type of reconstruction only exerts control over forward tibial shifting, not tibial rotation, when activities that exert high functional demands are undertaken. As a result, recent years have seen the appearance of numerous techniques for anatomic ACL reconstruction that reproduce both the anteromedial and posterolateral bundles of the ligament and therefore offer potentially improved rotational control. This article outlines a technique for anatomic ACL reconstruction. Said technique uses central and anteromedial portals, which afford a better perspective of the intercondylar notch. The main features of this technique are: (1) Double bone tunnels in the femur and tibia. The femoral tunnels are created using the out-in technique. (2) Double bundles with hamstring tendon grafts. (3) Tibial fixation by means of interference screws. (4) Femoral fixation in which the graft is supported by a cortical bone bridge and an interference screw in one of the tunnels. We feel that the main advantage of this technique is precisely that it introduces a new feature (a cortical femoral bone bridge) and is not necessarily dependent on specific double-bundle instrumentation, using only regular drill guides to create out-in femoral tunnels. This enables said tunnels to be located with ease and precision. The femoral fixation model itself, with the support provided by the cortical bone bridge, potentially guarantees a level of resistance that can be further increased with the aid of one or two interference screws, thus avoiding the need for post fixation techniques that require the use of screws or buttons.
