The ankle is located at the uppermost part of the foot and is called the ankle joint in clinical terms. This is the area where the foot and lower leg meet. If the patient moves the foot in a circular motion, he or she will see a very obvious joint at the top of the foot, which is the ankle joint, commonly known as the ankle. This part of the ankle joint is an important part of the lower limb weight-bearing, and it is mainly responsible for activities such as plantar flexion, dorsiflexion and rotation of the ankle, which can ensure that the human body makes activities such as running, jumping, stopping sharply and turning around. During human activities, this area is often prone to injuries, such as sprains or fractures of the ankle joint. Once this injury occurs, the body’s weight bearing is often significantly affected, which may lead to a significant limp.
