There are no tests to find out if you have osteoarthritis (OA). Your doctor may think you have OA because of your symptoms, their pattern, and a physical exam. Imaging tests such as
x-rays, ultrasound, or
can show if you have it. The tests can also find out how much damage you have. A joint with OA will have lost some of the normal space that is between the bones. This can be viewed on an imaging test.
