The Anterior Talofibular Ligament (ATFL) is a key ligament located in the ankle. It connects the talus bone to the fibula, providing stability to the ankle joint. The ATFL is particularly important in preventing excessive forward movement of the talus, which can occur during activities like running or jumping. Injuries to the ATFL are common, especially in sports that involve quick changes in direction. A sprain can occur when the ankle rolls inward, leading to pain and swelling. Proper rehabilitation and strengthening exercises are essential for recovery and to prevent future injuries.
