Four-Tunnel Double-Bundle Posterior Cruciate Ligament Reconstruction With Remnant Preservation

The clinical results of posterior cruciate ligament reconstruction (PCL) still leave much room for improvement. To get better knee stability, the double-bundle reconstruction, the use of strong grafts, and the preservation of the remnant have been applied. However, the combination of the 3 measures has seldom been reported. Thus I introduce a 4-tunnel double-bundle PCL reconstruction technique, in which I combine the use of strong grafts and preservation of the remnant. The critical point of this technique is manipulating skillfully across the femoral notch with the preservation, as well as the hindrance to operation of the PCL remnant. My clinical experience indicates this technique is somewhat complicated but most effective. I believe the introduction of this technique will provide an additional choice when PCL reconstruction is to be performed.
