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. Achilles tendon injuries are usually classified into two categories- partial and complete. Torn achilles tendons are typically grouped within the partial category, while ruptured achilles tendons can be classified as a complete tear. Those with feet that naturally turn outward are at larger risk for a torn tendon. The small degree of difference between a partial and complete achilles tear is usually experienced in the symptoms.
