The ankle joint is a crucial connection between the leg and the foot, allowing for movement and support. It is primarily made up of three bones: the tibia, the fibula, and the talus. This joint enables various movements, including walking, running, and jumping, by allowing the foot to flex and rotate. Surrounding the ankle joint are ligaments that provide stability and support. The joint is also cushioned by cartilage, which helps reduce friction during movement. Proper function of the ankle joint is essential for balance and mobility, making it vital for daily activities and sports.
