The word ‘arthritis’ means inflammation of the joint. It comes from a blend of Greek words - arthron (joint) and itis (inflammation). Although arthritis is often referred to as one disease, it’s not. There are more than 150 different types of arthritis. The two most common types of arthritis are osteoarthritis and rheumatoid arthritis.
Thinking of arthritis, we generally conjure up images of elderly citizens confined to wheelchairs, but two out of  very three people with arthritis are under the age of 65. If you’ve picked up this brochure then chances are you, or a loved one, either has or may have arthritis. This brochure will give you the essential information you need
to know about arthritis. With the right treatment and care, most people with arthritis can manage their condition to lead normal, or near-normal, lives. 
How does arthritis happen?
Your joints allow bones in your body to move smoothly against each other. In arthritis, joints can wear down, deform or become unstable. This causes pain and stops them from moving freely. Osteoarthritis and rheumatoid arthritis both act differently on the joints and show different symptoms.
