Ankle joint – Anatomy Atlas

Overview

Medial and lateral view of the ankle joint Considering its role in bearing the entire weight of the body, the ankle joint has several important ligaments that stabilize it during movement. The ligaments are divided into two groups: the medial (tibial) and lateral (fibular) collateral ligaments. The medial collateral ligament (a.k.a. deltoid ligament) is a strong band that prevents dislocations of the joint and consists of 4 elements: the tibionavicular, tibiocalcaneal, anterior tibiotalar and posterior tibiotalar ligaments. The lateral collateral ligament reinforces the lateral aspect of the ankle joint and is comprised of three distinct bands: the anterior talofibular, posterior talofibular, and calcaneofibular ligaments.
