What is osteoarthritis of the knee?
Osteoarthritis of the knee happens when the cartilage in your knee joint breaks down, enabling the bones to rub together. The friction makes your knees hurt, become stiff and sometimes swell. While osteoarthritis in the knee can’t be cured, there are many treatments to slow its progress and ease your symptoms. Surgery is an option for more severe forms of osteoarthritis.
