Achilles Tendon Disorder

The Achilles tendon can suffer from tendonitis, tendonosis, or rupture. Tendonitis is often a brief inflammation of the tendon. It sometimes progresses to tendonosis, which is a degeneration of the tendon that can cause structural problems and microscopic tears. In rare instances, chronic tendonosis can lead to a partial or complete rupture of the tendon. Disorders of the Achilles tendon frequently are caused by repetitive activity and, therefore, place athletes at especially high risk.
