Arthritis is a term that is caused by inflammation of joints. There are different types of arthritis. One of the inflammatory arthritis is Rheumatoid arthritis which is caused by the inflammation of the synovium which results in swelling of the other joints too. Osteoarthritis is the most common kind of arthritis which is caused due to wear and tear of the joints and thus happens mostly in old aged people. The cartilage slowly wears out and hence results in the clashing of bones and results in their wear and tear. The other type of arthritis is caused due to accumulation of uric acid in the joints.
