Degenerative osteoarthritis or just normal “wear and tear” is associated with degeneration of a joint. In this process, the cartilage itself is worn off of the cap of the joint. The underlying bone is then exposed, where there are many nerve endings. That leads to a process people commonly refer to as “bone-on-bone” arthritis. The subchondral bone is very sensitive, and it becomes very painful. Rheumatoid arthritis and avascular necrosis are some other common diseases associated with joint degeneration.

What are some other conditions that could lead to joint replacement?

Will my insurance cover a knee replacement surgery?
