Osteoarthritis is the most common form of arthritis in one or more joints. It is a degenerative,” wear-and-tear” type of arthritis that occurs most often in people 50 years of age and older, but may occur in younger people, too. In osteoarthritis, the cartilage in the knee joint gradually wears away as are the result of inflammatory changes in the joint. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone and produce painful bone spurs. To compensate, the bones often grow thicker, but this results in more friction and more pain. Osteoarthritis develops slowly and the pain it causes worsens over time.
