Arthritis is a term used to describe pain and inflammation affecting a joint. Any joint in the body can be affected by arthritis but the most commonly affected joints are those of the fingers and thumb, wrist, hip, knee, shoulder, lower back and neck. There are two main types of arthritis; osteoarthritis and inflammatory arthritis.

Osteoarthritis is the most common form of arthritis and is associated with increasing age, though it is a distinct entity from the changes associated with ageing. Osteoarthritis is a disease affecting the cartilage layer that covers the ends of bones at a joint and normally functions to provide a smooth surface that allows friction-free joint movement.

In osteoarthritis, there is a breakdown of the smooth cartilage layer which then tries to heal itself. There is gradual thinning of the cartilage layer with complete loss eventually. Osteoarthritis is characterised by pain and stiffness that is usually worse with movement and tends to be worst at the end of the day or after intense activity.

What is inflammatory arthritis?

Inflammatory arthritis describes a group of disorders where inflammation causes joint damage. The most common inflammatory arthritis is rheumatoid arthritis, a condition where the body’s own immune system initially causes damage to the inner lining of the joint, then damage to the smooth cartilage overlying the bone ends. Pain and stiffness is usually worse in the morning, gradually improving throughout the day. Unlike osteoarthritis, we have very effective medications that can help reduce the severity and slow the progression of rheumatoid arthritis.

How is it treated?

Osteoarthritis is best treated initially with simple measures including low impact exercise, strengthening, painkillers and walking sticks or supports. For osteoarthritis affecting your lower back or joints of your legs, you should try to lose weight as this can be very effective at reducing the severity of your symptoms.

Inflammatory arthritis is usually treated by a specialist with a combination of medications to help improve your symptoms and control the disease.

When should I see my doctor?

If you have had a painful joint or multiple painful joints that have not started to improve after a few weeks you should arrange to see your doctor who will examine you and arrange further investigations.

If your symptoms are severe you may be referred to see a specialist. Inflammatory arthritis is most often treated with specialised medications to reduce your symptoms and prevent progression. Osteoarthritis can be managed with injections or surgery depending on the joints affected.
