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.
The most common type of ankle injury is a sprained (stretched or torn) talofibular ligament on the outside of the ankle, although if it s a bad sprain you may also damage the calcaneofibular ligament. (Remember that ligaments get sprained, but muscles get strained).
