The inferior tibiofibular joint is the articulation between the distal parts of the tibia and fibula, where a small amount of rotation (transverse plane) is possible.Plantarflexion is the least stable position of the ankle joint, which explains why the majority of ankle injuries occur in this position. The ATFL, PTFL, and CFL support the lateral aspect of the ankle.The talocrural joint receives ligamentous support from a joint capsule and several ligaments, including the anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), calcaneofibular ligament (CFL), and deltoid ligament. It allows the movements of plantarflexion and dorsiflexion(sagittal plane).The Ankle Complex consists of 3 articulations The talocrural (ankle joint) ( Mortise joint) is a hinge joint between the inferior surface of the tibia and the superior surface of the talus.
