Double-Bundle, All-Inside Posterior Cruciate Ligament Reconstruction: A Technique Using 2 Separate Autologous Grafts

In a double-bundle posterior cruciate ligament reconstruction, several surgical techniques are available. Compared with other techniques, the advantages of the all-inside technique and cortical suspension devices with variable loop length are that shorter grafts can be used, tendons can be quadrupled, and a double-bundle posterior cruciate ligament reconstruction can be performed with autologous grafts. Furthermore, the all-inside technique provides independent outside-in socket reaming and is soft tissue, cortex, and bone sparing because no full diameter tunnels but sockets are created with a small diameter guide pin, which can transform into a retrograde drill. Sockets could however lead to bottoming out of the grafts at the femoral side and subsequent residual laxity. This can be avoided by using 2 separate grafts that are fixed in 2 femoral sockets before they are independently fixed and tensioned in 1 tibial socket in their corresponding flexion angle. In this technical note, we present a double-bundle, all-inside posterior cruciate ligament reconstruction using 2 separate autologous grafts.
