Operation procedure. (a) The proximal incision was made. (b) The medial and lateral portions of the Achilles tendon were sutured using the Krackow locking suture. (c) A distal incision was made, and the anchor bone channel was opened by drilling. (d) The arthro-pierce instrument was inserted and penetrated through the Achilles tendon, and the four tails of the two Orthocord sutures were pulled to emerge from the distal incision site using a PDS™ cord loop in the instrument. (e) The four tails of the two Orthocord sutures were simultaneously threaded through the knotless anchor. (f) The anchor was fixed to the calcaneus. It is essential to verify the appropriate depth of the knotless anchors before pressing them into the bone channel for secure fixation
