What is a double bundle ACL reconstruction?

Double Bundle ACL Surgery Instead of placing just one larger graft, the double-bundle ACL reconstruction procedure uses two smaller grafts. Therefore, there are essentially two ligament reconstructions, one for each bundle.

Can you have double ACL surgery?

A revision ACL reconstruction is a second surgery needed to repair a torn anterior cruciate ligament. This is a more challenging operation for the orthopedic surgeon.

Is the ACL a double bundle ligament?

Anatomical and biomechanical studies have shown that the anterior cruciate ligament (ACL) primarily consists of 2 distinct bundles, the anteromedial (AM) and posterolateral (PL), which act separately during the knee’s range of motion.

How Long Does ACL revision surgery take?

The procedure usually takes less than two hours. It will require an incision to remove a tendon if you are undergoing an autograft, in which a tendon from another part of your body is inserted in your knee.

When to have double bundle ACL reconstruction surgery?

Double Bundle ACL Reconstruction Surgery. In order to restore stability to the knee, your doctor may recommend an ACL reconstruction to insert a new ligament in the place of the damaged ACL. A newer technique, called a double-bundle ACL reconstruction, has been developed to better replicate the function of the normal ACL.

When to widen the notch for ACL reconstruction?

Widening the notch is especially necessary in the PCL dominant notch, where the PCL occupies 60% to 80% of the cross-sectional area of the notch leaving little room for an ACL graft that is wider and rounder than the narrow, spindle-shaped intact ACL.

How are the grafts held in place during ACL reconstruction?

When the ACL is reconstructed, the graft is placed in the position of the anteromedial bundle. Grafts are held in place by making a hole in the bone called a tunnel. One tunnel is made in the femur and one in the tibia. The graft is held in the bone with a fixation device, often a screw.

What are the two bundles of the ACL?

The ACL is composed of two functional bundles, the AM and PL bundle. The AM bundle primarily controls AP stability and the PL bundle primarily functions to control rotation. The second principle is restoring the native insertion site anatomy of the ACL.
