An injury to the anterior talofibular ligament (ATFL) is the most common type of lateral ankle sprain. The ATFL connects the talus (ankle bone) to the fibula. Anterior talofibular ligament sprain symptoms include pain or soreness, swelling, difficulty walking, bruising, and stiffness in the joint.
Importance of Test: The anterior drawer test is a beneficial test to perform in a patient following an inversion ankle sprain (injury to the lateral collateral ligaments). The 3 main components of the Lateral Collateral Ligaments of the ankle include the anterior talofibular ligament (ATFL), calcaneofibular ligament, and posterior talofibular ligament.
