An Achilles tendon rupture is a common injury that involves a tearing of the thick band of tissue that connects the calf muscle to the heel and helps with nearly any kind of foot movement. The Achilles tendon can be partially or completely torn and most commonly occurs as a result of repeated stress on the tendon.

Many Achilles tendon ruptures require surgery to repair the tendon and allow the patient to resume normal activity. Nonsurgical treatment is generally reserved for partial tears or for patients who lead a sedentary lifestyle. Neglected ruptures can lead to chronic weakness and difficult walking.
