A healthy knee has cartilage and lubricating fluid (synovial fluid) to protect and cushion the bones, allowing the knee to move and bend.

In knee osteoarthritis, it is a condition which the cartilage wears away, and the joint fluid loses its shock absorbing qualities. If this happens, the bones may rub each other and resulting pain, stiffness and swelling.
