Osteoarthritis
Osteoarthritis is the most common form of joint disease. It affects the whole joint including bone, cartilage, ligaments and muscles. Although often described as ‘wear and tear’, this is not an accurate description of osteoarthritis. Osteoarthritis is now thought to be the result of a joint working extra hard to repair itself.
Rheumatoid arthritis
Rheumatoid arthritis (RA), a common inflammatory form of arthritis, is an autoimmune disease that causes pain and swelling of the joints. 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.
Ankylosing spondylitis
Ankylosing spondylitis (AS) is a condition that mainly affects the spine. The joints of the neck, back and pelvis become inflamed, causing pain and stiffness. Other joints, such as the hips and shoulders, and other areas of the body such as the eyes, skin, bowel and lungs, can also be involved. Symptoms of AS usually begin between the ages of 15 and 45 years.
Psoriatic arthritis
Psoriatic arthritis is a condition that causes inflammation of the joints. This causes the joints to become painful, stiff and often swollen. Usually only people who have a skin disease called psoriasis are affected by psoriatic arthritis.
Gout
Gout is a common and painful condition that affects the joints. Small crystals form in and around the joint, causing inflammation, pain and swelling. An attack of gout usually comes on very quickly, often overnight. The joint becomes very red, swollen and extremely painful. Gout normally affects one joint at a time, often the joint of the big toe.
Juvenile idiopathic arthritis (children)
Juvenile idiopathic arthritis (JIA) is the name given to a number of types of arthritis that occur in children. We do know that JIA is an autoimmune condition. This means the body’s immune system (its protective mechanism against infection) starts to mistakenly attack healthy cells of the body.
