Frequently Asked Questions
1. What is osteoarthritis?
Osteoarthritis is the most common form of arthritis among older people. It affects hands, low back, neck, and weight-bearing joints such as knees, hips, and feet.
Osteoarthritis occurs when cartilage, the tissue that cushions the ends of the bones within the joints, breaks down and wears away. This causes bones to rub together, causing pain, swelling, and loss of motion of the joint.
