Know the difference between Rheumatoid Arthritis and Osteoarthritis
According to the survey by Australian Institute of Health and Welfare, 1 in 6 Australians have arthritis. There are several different types of arthritis. Osteoarthritis (OA) and rheumatoid arthritis (RA) are two of the most common forms. Although the symptoms of these two types of arthritis can be similar, it’s very important to distinguish between them in order to determine the proper treatment.
Rheumatoid arthritis (RA) is an autoimmune disease. The normal role of your body’s immune system is to fight off infections to keep you healthy. In an autoimmune disease, your immune system starts attacking your own healthy tissues. In RA, the immune system targets the lining of the joints, causing inflammation and joint damage.

Osteoarthritis (OA) occurs when the smooth cartilage joint surface wears out. And as the joint works extra hard to repair itself, that can cause inflammation and pain which affects the whole joint including bone, cartilage, ligaments and muscles.
The table below summarise the differences between RA and OA:
Rheumatoid Arthritis | Osteoarthritis | |
Nature of the disease | Autoimmune disease | Degenerative disease |
Prevalence in Australia | 2% of the population | 9% of the population |
Risk factors |
Family history of RA Smoking History Women > Men |
Overweight Previous injury to the joint Overuse a particular joint Women > Men |
Age of onset | Most commonly 35-64 | Usually begins later in life |
Joint-related symptoms |
Symmetrical presentation Affect smaller joints (fingers, elbow, foot) Joint pain, swelling, and tenderness to touch |
Symptoms often begin on one side of the body Affect large weight-bearing joints (hips, knees), or the spine Joint pain, swelling, and tenderness to touch |
Other symptoms | Frequent fatigue and a general feeling of being ill | Whole-body symptoms are not present |
Diagnosis |
Blood test for inflammation and antibodies X-ray at later stage |
X-ray |
