• Knee Osteoarthritis (OA) is a deterioration of the cartilage covering of the knee joint.
• Some OA change is normal as we age however symptoms are affected by a range of factors such as being overweight, lower limb weakness or poor mechanics, history of trauma to the knee or a family history of OA among others.
• Symptoms include pain, swelling and stiffness of the knee along with possible clicking, grinding, or clunking of the joint.
• Importantly, while Xray is often used to diagnose OA, there has been shown to be quite a poor correlation between changes on imaging and the degree of symptoms experienced.
• Treatment generally involves education, activity modification to avoid joint overload and exercises to strengthen the leg and improve mechanics.
• This may be done in conjunction with other adjuncts such as manual therapy, medications, taping, bracing and advice on weight loss.
• High-level evidence shows that exercise and physical activity are key to reducing inflammation and pain and improving function.
• In more severe cases, joint replacement surgery may be required but should only be considered after failing to achieve adequate results with conservative management.
• Recent studies have shown that up to 30% of those waiting for joint replacement surgery opted out of surgery after undertaking an appropriate course of exercise due to the improvement in their symptoms and function.
