Achilles Tendinitis Definition


Updated November 13, 2013

Definition: Achilles tendinitis is a syndrome of irritation of the Achilles tendon in the ankle. The Achilles tendon is the large tendon in the back of the ankle that inserts into the heel bone (calcaneus). When individuals overuse their Achilles tendon it may become irritated and inflamed. This inflammation can cause pain and swelling.

Achilles tendonitis, an acute inflammation, is different from Achilles tendinosis, a chronic condition of degeneration of the Achilles tendon.  How much these conditions contribute to the risk of Achilles tendon rupture is debated.

Also Known As: Heel Cord Injury, Achilles Heel Injury

Alternate Spellings: Achilles Tendonitis
