Strong tissues, called ligaments, connect our leg and foot bones together.One ligament, called the Lateral Collateral Ligament (LCL), is very susceptible to an ankle sprain. The LCL is located on the lateral side of our ankle, and it contributes to balance and stability when we are standing or walking and moving. This ligament has three separate bands: The Anterior Talofibular ligament, Calcaneofibular ligament, and Posterior Talofibular ligament. These ligaments protect the ankle joint from abnormal movements, such as extreme range of motion, twisting, and rolling. The Anterior Talofibular ligament is the weakest and most commonly injured.
