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.
What is the Anterior Cruciate Ligament - ACL? The anterior cruciate ligament (ACL) is one of four ligaments critical to stabilizing the knee joint. A ligament is made of tough fibrous material and functions to control excessive motion by limiting joint mobility. Of the four major ligaments of the knee, the ACL is the most frequently injured.
