The two most commonly occurring kinds of arthritis, are rheumatoid arthritis and osteoarthritis

Rheumatoid arthritis  

Rheumatoid arthritis is an autoimmune disease, and it results in chronic inflammation of the joints, and affects many joints. The auto-immune inflammation causes damage to the lining of the joint, cartilage damage, and even ligament damage


With OA the joint cartilage is mainly affected. Joint cartilage is a cushioning layer of tissue which lines the ends of the bones where they move against other bones to form a smoothly moving joint.    

When someone has osteoarthritis the joint cartilage has started to degenerate  and this gets worse and time goes by, causing damage to the subchondral bone and other structures in the joint.
