What It Is

Osteoarthritis, sometimes called OA or just arthritis, is one form of the many different types of arthritis. However, it is by far the most common type of arthritis in the UK (NHS, 2023a). Osteoarthritis literally translates to mean "bone and joint inflammation".

The condition may run in families. So if your parent or grandparent has osteoarthritis, you may be more likely to develop it too (NHS, 2023a).

OA used to be thought of simply as "wear and tear", but that is not the whole story. As part of normal life, your joints are exposed to a constant low level of damage, which the body usually repairs without you noticing. In OA, the joint can no longer repair itself as well as it once could, and the protective cartilage on the ends of the bones starts to break down (NHS, 2023a; Arthritis UK, n.d.). Your risk of OA increases as you get older (NHS, 2023a).

Almost any joint in the body can be affected by OA, but it most often causes problems in the knees, hips and small joints of the hands (NHS, 2023a). The spine and feet can also be affected. Sometimes just one joint is affected, but often several joints are affected at different speeds. So it is not uncommon to first notice some hip stiffness on one side, only to be followed months or years later by similar symptoms on the other side.

Several things are thought to increase the risk of OA, including a previous injury or operation on the joint, being overweight, getting older, a family history of OA, being a woman, and exercise or work that puts frequent strain on the joints (NHS, 2023a).

OA is different to rheumatoid arthritis. Rheumatoid arthritis is an autoimmune disease, which means the immune system attacks the cells that line the joints by mistake, making them swollen, stiff and painful (NHS, 2023c). Stiffness that lasts a long time in the morning can be a sign of rheumatoid arthritis rather than OA (NHS, 2023a). OA should also not be confused with osteoporosis. Osteoporosis is bone thinning, and has nothing to do with OA. Osteoporosis tends to be painless, and is known as a silent disease, until you fracture a bone from a fall or injury. With OA, fracture is far less likely, and it tends to be more painful generally.

Having OA does not mean you will suffer with pain for the rest of your life. OA is a long-term condition, but it does not necessarily get any worse over time and it can sometimes gradually improve (NHS, 2023a). Symptoms can be helped with exercise, losing weight if you need to, hot or cold packs and physical therapies (NHS, 2023b).

Osteoarthritis Anatomy

The skeletal system is made up of all the joints and bones in the body. Where two bones connect, it forms a joint. A joint helps us to twist, turn, bend, walk, run, climb, or get into a particular position. In a healthy joint, the ends of the bones are covered with cartilage, a tough but smooth and slippery tissue that helps the bones move freely against each other (Arthritis UK, n.d.). When a joint develops OA, part of the cartilage thins and its surface becomes rougher, so the joint doesn't move as smoothly as it should (Arthritis UK, n.d.). Bony growths can develop around the edge of the joint, and the area can become swollen (NHS, 2023a; Arthritis UK, n.d.).
