Tendonitis Vs. Tendonosis

What are tendons?

Tendons are bands of tissue that anchor the muscles to the bones. They have a lubricating cover keeps them where they are supposed to be. Having the ability to withstand tension, the tendons and muscles work together to help move bones.


itis — means inflammation. The term tendonitis should be reserved for tendon injuries that involve acute injuries accompanied by inflammation

osis — implies a pathology or chronic degeneration without inflammation, so doctors prefer the term tendonosis for chronic tendon injuries that don’t heal properly

What is Tendonitis

Tendonitis is an inflammation of the tendon, which can be caused by repetitive action, overuse, or improper movement. Other causes are aging and certain diseases such as diabetes or rheumatoid arthritis.

Recovery Time
Early detection – a couple days to two weeks
Chronic presentation – four to six weeks

What is Tendonosis

Tendonosis is a chronic degeneration without inflammation. Caused mainly by overuse without giving the tendon time to heal. Having microscopic injuries that don’t completely heal before re-injury is what causes pain without inflammation.

Recovery Time
Early detection – six to ten weeks
Chronic presentation – three to six months
