The most common type of arthritis in the UK is osteoarthritis, affecting nearly nine million people.
To begin with, it compromises the smooth cartilage lining of the joint, making movement more difficult and leading to pain and stiffness.
It typically affects joints in the hands, knees, spine and hips.
The second most common type of arthritis is rheumatoid arthritis, which is when the body’s immune system targets affected joints, causing pain and swelling.
