In rheumatoid arthritis, the body's immune system attacks the lining of the joint capsule, a tough membrane that encloses all the joint parts. This lining, known as the synovial membrane, becomes inflamed and swollen. The disease process can eventually destroy cartilage and bone within the joint.

Determining the cause of arthritis has proved to be difficult, but there are several factors that can cause it. Some scientists argue that arthritis is hereditary. The genes can transmit this disorder from one generation to another. Age is another factor. As people grow old, the joint cartilages will become brittle and have less power to repair them.
