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.
