What is osteoarthritis?
Osteoarthritis (OA) is an active disease process where we see changes to the tissues within the joint. In a healthy joint, our bones are covered with a smooth coating of tissue called cartilage, which allows our bones to move freely. Over time, this cartilage can thin and become rough, leading to restrictions in joint mobility.
With progression of OA, extra bone may form around the joint in a response to these changes. As a result, our joints can swell, and become stiff and painful.
This can occur in any joint within the body, however is most common in the knees and hips. OA is the most common form of arthritis, affecting around 2.2 million Australians according to the Australian Bureau of Statistics.
What causes it?
There are many factors that can contribute to the development of osteoarthritis, such as age, genetics or abnormal repetitive forces. However, it is likely most people will experience some degree of normal degeneration and may not experience any symptoms as a result.
How can OA be managed?
Regular exercise can reduce joint stiffness, improve muscle strength and reduce joint pain and swelling. Many high quality research studies show exercise is helpful in managing symptoms associated with osteoarthritis. Exercise therapy is a great way to preserve joint mobility, reduce pain and maintain a healthy lifestyle. Severe joint pain is most commonly seen in inactive adults with osteoarthritis.
The best prevention for OA is to maintain a healthy lifestyle and participate in regular exercise, maintain a healthy weight and avoid repetitive overuse of joints.
