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.
About half of all injuries to the anterior cruciate ligament occur along with damage to other structures in the knee, such as articular cartilage, meniscus, or other ligaments. Injured ligaments are considered sprains and are graded on a severity scale. Grade 1 Sprains.bout half of all injuries to the anterior cruciate ligament occur along with damage to other structures in the knee, such as articular cartilage, meniscus, or other ligaments.
