If the Achilles tendon is torn, this is called an Achilles tendon rupture. The tear may be either partial or complete. In a partial tear, the tendon is partly torn but still joined to the calf muscle. With complete tears, the tendon is completely torn so that the connection between the calf muscles and the ankle bone is lost.
