Illustrations of the operative technique. a Avulsed bone fragment was removed from the tendon, and the Achilles tendon end was debrided. Three bone tunnels arranged in a triangle shape were drilled using a 1.5-mm Kirschner wire through the bone spurs base. b The Achilles tendon was woven with two sutures. Three 12 G syringe needles with 4-0 thread loop passed tunnels to pull the four free ends of sutures through the tunnels. The Achilles tendon end was reattached to the insertional site. c The Achilles tendon was pulled back down to the insertional site
