Abstract:
We describe a technique for arthroscopic anterior cruciate ligament (ACL) reconstruction using the middle third of the quadriceps tendon without a patellar bone block and absorbable tibial and femoral cross-pin fixation. The central part of the quadriceps tendon is harvested through a 5-cm long anterior skin incision without a patellar bone block. Tibial and femoral tunnels are prepared, the graft is passed up the tunnels, and is fixed both in the femur and the tibia using absorbable cross pins (Rigid Fix; Mitek, Johnson & Johnson, Norwood, MA). In this way, the graft is stabilized near the joint line, providing outlet fixation. In our practice, very good results have been obtained with the use of this technique.
