Types and causes of arthritis
Types and causes of arthritis
The two main types of arthritis — osteoarthritis and rheumatoid arthritis — damage joints in different ways.
Osteoarthritis
The most common type of arthritis, osteoarthritis involves wear-and-tear damage to a joint’s cartilage. This wear and tear can occur over many years, or it can be hastened by a joint injury or infection. Osteoarthritis also causes changes in the bones and deterioration of the connective tissues that attach muscle to bone and hold the joint together.
Rheumatoid arthritis
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 (synovial membrane) becomes inflamed and swollen. The disease process can eventually destroy cartilage and bone within the joint.
