Synovitis may occur in association with arthritis as well as lupus, gout, and other conditions. Synovitis is more commonly found in rheumatoid arthritis than in other forms of arthritis, and can thus serve as a distinguishing factor, although it can be present to a lesser degree in osteoarthritis. Long term occurrence of synovitis can result in degeneration of the joint.
Synovitis symptoms can be treated with anti-inflammatory drugs such as NSAIDs. An injection of steroids may be done, directly into the affected joint. Specific treatment depends on the underlying cause of the synovitis.
