Ligaments of Ankle Joint. There are two sets of ligaments, that originate from individual malleolus. The medial ligament (known as deltoid ligament) is connected to the medial malleolus. It consists of four separate ligaments, that fan out from the malleolus, connecting to the talus, calcaneus, and navicular bones.

What are the ligaments in the ankle?
The lateral collateral ligament is a strong compound ligament that reinforces the lateral aspect of the ankle joint. It is comprised of three distinct bands: 1 Anterior talofibular ligament: a weak, flat band that originates on the lateral malleolus of the fibula and extends anteromedially to the lateral side of the neck of the talus. 2 Posterior talofibular ligament: a strong band that extends medially and posteriorly from the distal part of the lateral malleolar fossa of the fibula to the lateral tubercle of the talus. It is also connected to the medial malleolus by a tibial slip of fibres. 3 Calcaneofibular ligament: a long band that originates from the apex of the lateral malleolus of the fibula, and extends posteroinferiorly to attach on a tubercle on the lateral aspect of the calcaneus.
