Achilles Tendinitis / Achilles Tendonosis
Achilles tendinitis and Achilles tendonosis are usually caused by a sudden increase of a repetitive activity involving the Achilles tendon. Achilles tendinitis describes an inflammation of the Achilles tendon. Although the inflammation is generally short-lived initially, over time the condition may progress into a degeneration of the tendon whereby it loses its organized structure. This is known as Achilles tendonosis and can involve the development of microscopic tears. Symptoms include pain, stiffness, soreness, or tenderness of the tendon. This often occurs in the morning or after periods of rest. When the disorder progresses to degeneration, there may be an enlargement of the tendon accompanied by the development of nodules in the area where the tissue is damaged. Treatment options include immobilization, ice, nonsteroidal anti-inflammatory drugs (NSAIDs), laser therapy, orthotics, night splints, and physical therapy.
“Intense physical activity such as running and jumping can lead to painful inflammation of the Achilles tendon. Insertional Achilles tendonitis affects the tendon where it attaches to the heel bone, while noninsertional Achilles tendinitis involves the middle portion of the tendon.”
