Injury to the medial deltoid ligament complex is rare as it is the strongest of the ankle ligaments. However, damage to this structure can occur, often in association with an avulsion fracture of the medial malleolus due to the ligamentous strength of the complex. Deltoid ligament repair remains a primary option for patients with severe acute injuries, or patients with chronic instability who have failed conservative measures. Repair of the medial ankle ligaments provides improved stability with reduced risk of recurrent sprains and potential damage to local cartilage. We present a case of a young woman with concomitant medial and lateral ankle instability who successfully underwent deltoid ligament repair for her medial ligament injury.
