Anatomic double-bundle posterior cruciate ligament reconstruction using double-double tunnel with tibial anterior and posterior fresh-frozen allograft.
Techniques for the reconstruction of knee ligaments must restore the injured knee to a satisfactory level of performance. For this, a precise anatomic reconstruction is necessary. Many arthroscopic techniques for reconstruction of the posterior cruciate ligament (PCL) have been reported to restore the normal anatomy of the intact PCL using a double-bundle reconstruction with a Y-shaped tendon graft (2 femoral tunnel and 1 tibial tunnel). However, this procedure is sometimes difficult because the graft must be tightened in different grades of flexion to obtain complete strength of both bundles. We thought that double-bundle PCL reconstruction using double-double tunnels (2 femoral and 2 tibial tunnels) would allow an anatomic reconstruction, restoring better knee biomechanics, and probably improving patient outcome.
