The Achilles Tendon is a long, thick band of connective tissue that attaches the calf muscles to the heel bone. It is the longest and strongest tendon in the body, meant to endure stress from daily activities and sports. The achilles tendon allows us to walk, run, jump, and stand on our toes. However, the achilles tendon can tear, rupture, and degenerate over time. Typically a tear or rupture occurs due to a sudden, strong force during tough physical activity. A rupture can also occur during unusual fast movements or pivoting the foot. Those with a foot that naturally turns outward are at larger risk for a torn tendon. A rupture achilles tendon can cause pain, bruising, and swelling near the back of the calf and heel. Patients who can not bend their foot downward or struggle to walk or stand may be experiencing a rupture tendon. Achilles tendon repair surgery may be helpful for patients who have tendon injuries that make it difficult for them to move a joint or are unbearably painful.
