Osteoarthritis

Osteoarthritis is a common chronic joint disease, causing large amounts of disability and pain in the Australian community. There are a number of risk factors for osteoarthritis including excess weight or obesity, joint injury, repetitive kneeling or squatting and repetitive heavy lifting.

Three key characteristics of osteoarthritis are:

  • mild inflammation of the tissues in and around the joints
  • damage to cartilage, the strong, smooth surface that lines the bones and allows joints to move easily and without friction
  • bony growths that develop around the edge of the joints.

Osteoarthritis mostly occurs in the knees, hips and small joints of the hands and base of the big toe. However, almost any joint can be affected.

If you think you may have osteoarthritis then you should see your doctor. There is no definitive test to diagnose the condition, so they will ask you about your symptoms and examine your joints and muscles.

Osteoarthritis (OA) is a degenerative joint disease caused by wear and tear of the joint cartilage and the formation of new bone (bone spurs) at the edges of the joints. The cartilage of the affected joint wears down until there is none left and the opposing bones rub together. The joints most commonly affected are those of the hips, knees, fingers, big toe and spine. Risk factors for osteoarthritis include age, female sex, obesity and joint injury.
