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 anterior talofibular ligament arises from the anterior margin of the lateral malleolus and extends anteromedially to the lateral malleolar facet and the lateral aspect of the neck of the talus bone.
—The fibers of the posterior talofibular ligament run horizontally from the malleolar fossa of the fibula to the lateral tubercle of the talus.
—The calcaneofibular ligament arises just anterior to the apex of the lateral malleolus and extends to the lateral surface of calcaneus.
