There are many different types of arthritis one can get in their life. In particular to knee arthritis, the two most prevalent types are Osteoarthritis (OA) and Rheumatoid Arthritis (RA). Osteoarthritis is the more common type of arthritis and is a progressively degenerative condition by which the cartilage is continually worn away. Rheumatoid Arthritis, on the other hand, is an inflammatory condition that can affect a person regardless of age. Rather than a specified area, RA is an autoimmune disease that affects the entire body.
While these are serious issues, if the pain is localized, many may be unable to tell whether or not they are suffering from arthritis proper or another issue such as a simple knee injury. In this article, we are going to help resolve that issue and go over whether you have simply suffered a bruised knee, or may have something considerably more serious.
