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.
Lateral collateral ligament (LCL) sprain occurs when the ligament on the outer side of the knee is overstretched. Collateral ligament knee injuries make up about 25% of severe knee injuries in the United States. They most often occur in adults aged 20-34 years and 55-65 years.LCL sprains mainly happen during sporting activities, including contact and noncontact sports, and affect women and men equally.ollateral ligament knee injuries make up about 25% of severe knee injuries in the United States.
