Steps for cutting the anterior half of the peroneus longus tendon. A An incision was made above the posterior aspect of the lateral ankle tip to reveal the peroneus longus tendon; B the anterior half of the tendon was picked out with hemostatic forceps; C the selected portion of the tendon was tied with No. 2 Ethibond sutures; D the ankle was dorsally extended and turned outward, and the distal end of the tendon was sufficiently revealed to dissect the anterior half of the tendon; E the distal end of the tendon was implanted in the tendon retriever, and the tendon was stripped along the peroneal alignment in the direction of the head of the peroneal bone; F the anterior half of the tendon was removed in its entire length
