The Achilles tendon is located behind the heel bone and the ankle joint, where the greater tendon is located. Under normal circumstances, if the patient exposes the foot and ankle joint and takes a position on tiptoe, a taut tendon is clearly visible in this area, which is the Achilles tendon. The Achilles tendon is a tendon that emanates from the triceps muscle of the lower leg and ends at the heel tuberosity, which is the most powerful tendon in the body and therefore carries a very heavy load. In the process of standing or walking, the Achilles tendon is needed to complete the movement. In this case, the calf triceps muscle contracts and transmits to the Achilles tendon, which in turn pulls the Achilles bone and allows the patient to perform the above activities.
