Fig 4.

Type of graft used. Achilles tendon allograft with the calcaneal tuberosity still attached. It originally comes with a large bone block and a single tendinous structure. The bone block is fashioned to a width and length of 2 cm each and a depth of 0.8 cm. The single tendinous structure is split longitudinally 50% of its length into 2 strands starting at the free end (non-bony end) to replicate the iliofemoral ligament (allowing for a Y-configuration). The figures depicting the surgical procedure are in a supine position, on a left hip. Proximal, distal, medial, and lateral are the top, bottom, left, and right of the image, respectively.
