Structure
The lateral collateral ligament of the ankle joint is a complex of strong ligaments found on the lateral aspect of the ankle. It is composed of three distinct parts, including the calcaneofibular and the anterior and posterior talofibular ligaments.
The fibers of the posterior talofibular ligament run horizontally from the malleolar fossa of the fibula to the lateral tubercle of the talus.
