The ankle joint is a crucial connection between the tibia and fibula bones of the lower leg and the talus bone of the foot. It allows for a range of movements, including flexion and extension, which are essential for walking, running, and jumping. The joint is supported by ligaments that provide stability and help prevent excessive movement. In addition to its primary function, the ankle joint plays a vital role in maintaining balance and adapting to uneven surfaces. Proper functioning of this joint is important for overall mobility and can be affected by injuries, such as sprains or fractures, which may require medical attention for recovery.
