What Is the Anterior Talofibular Ligament?
The anterior talofibular ligament is a band of connective tissue located along the outside of the ankle joint. It originates on the fibular malleolus, the bony protrusion on the outside of the ankle joint, and then runs forward and inward to connect to the talus bone. The talus bone is an irregularly shaped bone in the foot that articulates with the tibia and fibula bones of the lower leg, forming the ankle joint. Because the anterior talofibular ligament crosses the outside or lateral aspect of the ankle joint, it is the ligament in the body most commonly sprained, typically when the foot is rolled to the outside.
