How Is Osteoarthritis Diagnosed?
The diagnosis of osteoarthritis is based on a combination of the following factors:
• Your description of symptoms.
• The location and pattern of pain.
• Physical exam.
Your doctor may use X-rays to help confirm the diagnosis and make sure you don’t have another type of arthritis. X-rays show how much joint damage has occurred.
Sometimes blood tests will be given to determine if you have a different type of arthritis.
If fluid has accumulated in the joints, your doctor may remove some of the fluid (called joint aspiration) for examination under a microscope to rule out other diseases
