Achilles << uh KIHL eez >> tendon is the tendon at the back of the ankle. It attaches the muscles of the calf to the heel bone and is one of the strongest tendons in the body. The name Achilles tendon comes from the legend of Achilles, a Greek hero killed by an arrow in the heel.
The Achilles tendon may rupture as the result of a powerful upward movement of the foot or a blow to the calf when the calf muscles are contracted. This injury most commonly occurs in people over age 30 who compete in sports that involve running. Complete rupture often is accompanied by a snap, severe pain, and the inability to push off or stand on the toes. As soon as possible, ice should be applied to the back of the ankle and the leg should be raised and immobilized. Surgery may be necessary to sew the tendon together. The person should stay off the injured leg for up to two months before beginning a program of gradual stretching and strengthening exercises. Full recovery may take a year or more.
