Biomechanics of the ankle

The biomechanics of the ankle involve how its bones, muscles, tendons, and ligaments work together to enable movement and stability. The main bones, the tibia, fibula, and talus, form a hinge that allows up-and-down motion (dorsiflexion and plantarflexion). Ligaments support the joint and prevent excessive movement, while muscles control motion and provide strength. When you walk or run, the ankle absorbs shock and pushes you forward, maintaining balance. Proper function depends on the coordinated effort of these structures, allowing smooth, stable movement and adaptation to uneven surfaces.
