Procedures used to expose and isolate the PTT. (A) With a 2-cm medial incision, the tendon was divided at its insertion to the navicular region, preserving as much length as possible. (B) The distal tip of the medial malleolus was confirmed with a small screw as a marker. (C) A second 2-cm long incision posterior to the medial region of the tibial crest was made along the fascia of the calf, where the upper edge was 3 cm proximal to the distal tip of the medial malleolus. (D) PTT was isolated and then re-routed.
