The Transportal Graft Passage in Transtibial Posterior Cruciate Ligament Reconstruction With a Bone–Patellar Tendon–Bone Graft

Abstract

Posterior cruciate ligament injury is one of the most common problems in sports medicine. The treatment of choice for this injury is posterior cruciate ligament reconstruction, which improves the biomechanical and clinical stabilities of the knee. There are many graft choices, of which the bone–patellar tendon–bone (BPTB) graft is a popular option. In applying the BPTB graft, most surgeons use the transtibial technique by passing the graft from the tibial tunnel to the femoral tunnel, which is normally performed without problems, but there is a chance of patellar tendon fiber damage because of the sharp turn required from the tibial tunnel to the femoral tunnel. To minimize this risk, herein we propose a transportal graft passage technique with which it is easy to pass the BPTB graft and reduce the risk of graft damage.
