The joint capsule is white fibrocartilage and surrounds the joint, attaching superiorly and inferiorly to the edge of the articular surfaces and anteriorly to the neck of the talus. It is relatively thin on its anterior and posterior aspects, with strong lateral and medial collateral ligaments. The extrinsic ligaments are the deltoid on the medial aspect and the tripartate laterally. The deltoid ligament is triangular, attaching superiorly to the medial malleolus and inferiorly to the tubercle of the navicular, the sustentaculum tali and the medial surface of the talus. The lateral or tripartite ligament has three components: anterior talofibular, posterior talofibular and the calcaneofibular. Blood supply is derived from the anterior and posterior tibial arteries and the nerve supply is from the peroneal branches of the anterior and posterior tibial nerves.

o The medial ligament is called the deltoid ligament and is a strong band attached to the medial malleolus; it is triangular in shape with superficial and deep fibres. Superficial fibres pass to the navicular, calcaneum and talus. The deep fibres have a strong anterior and posterior component called the anterior and posterior tibiota- lar ligaments (Fig. 9.20).

Under dynamic inversion, the F05 model exhibited an increase in the moment monotonically and put the lateral ligament (e.g. the CF ligament) into tension up to failure. Compared to the only female subject available in the experimental dataset (54 years old, 163 cm height and 50.0 kg weight), the F05 model predicted comparable peak moment (19.4 Nm vs. 24.5 Nm) but lower angle on occurrence of ligament rupture (17.8° vs. 32.3°; Figure 4(a)). Under dynamic eversion, the F05 model provides similar curve shape as M50 up to approximately 24° of eversion while lower peak value of the moment (Figure 4(b)). For injury prediction, the F05 model provided similar angle at the occurrence of ligament rupture and the same injury patterns (i.e. deltoid ligament rupture and medial malleolus fracture) compared to the one female subject (66 years old, 163 cm height and 60.0 kg weight).
