Achilles tendon injuries affect the Achilles tendon, a fibrous band of tissue that links the muscles in your calf to your heel. The strength and flexibility of this tendon are important for jumping, running, and walking.
Your Achilles tendon is a large band of tissue in the back of your ankle. It connects your calf muscles to your heel bone. You use it almost every time you move your leg. But repeated stress can make the tendon more prone to injury. A complete tear through the tendon is known as an Achilles tendon rupture.
