The tibialis anterior tendon (TAT) is the most medially located tendon of the anterior ankle. It originates from the junction between lower and middle thirds of the tibia and courses towards the medial border of the foot, passing under the superior and inferior extensor retinacula, inserting vertically on the first metatarsal base and the medial cuneiform bone [1–3]. The saphenous nerve runs along the medial side of the TAT and crosses over the tendon close to its insertion. The deep peroneal nerve runs along the posterolateral side of TAT and crosses under the extensor hallucis longus (EHL) tendon just above the ankle level to the lateral side of EHL tendon.
