Cobra tongue shaped allograft augmentation of neglected patellar tendon rupture

We present a case of neglected patellar tendon avulsion after failed fixation. During the reconstruction of this injury, the Achilles tendon-Calcaneal bone allograft was fashioned like a cobra bifid tongue, and used for augmentation. Distally fixed in bone sockets that were each secured with an interference screw. While proximally the allograft tendon was sutured to the quadriceps tendon. This unique configuration was used to provide bone to bone fixation over the tibial side and to maximize the surface area of augmentation.
