<unk>  is the medical term for inflammation of the<unk> ovial membrane. This membrane lines joints that possess cavities, known as<unk> ovial joints. The condition is usually painful, particularly when the joint is moved. The joint usually swells due to<unk> ovial fluid collection.<unk>  may occur in association with arthritis as well as lupus, gout, and other conditions.<unk>  is more commonly found in rheumatoid arthritis than in other forms of arthritis, and can thus serve as a distinguishing factor, although it is also present in many joints affected with osteoarthritis. In rheumatoid arthritis, the fibroblast-like<unk> oviocytes, highly specialized mesenchymal cells found in the<unk> ovial membrane, play an active and prominent role in the<unk> . Long term occurrence of<unk>  can result in degeneration of the joint.
