Optional technique of cancellous bone tip transplantation (right ankle). (A) Funnel-shaped device. (B) If the screw is not firmly fixed, a bigger size screw or cancellous bone tips are grafted to the space between the tunnel and tendon graft using a funnel-shaped device and a flat-ended 3-mm Kirschner wire for pushing bone tips. The cancellous bone can be harvested from the knee or from the allograft. This indicates the transplantation of the bone tips into the talar tunnel through the AAL portal using a funnel-shaped device and a Kirshner wire. Parts (A) and (B) are from different patients than that of the video case because of the optional technique. (AAL, accessory anterolateral.)
