Pannus and Rheumatoid Arthritis

1What Is Pannus?

Most joints in the human body are covered by a delicate, thin layer of lining. When this layer is inflamed, it leads to an abnormal tissue growth called pannus. This growth may develop uncontrollably and cover the surfaces of the cartilage or bones. The formation of pannus is typically seen in people with rheumatoid arthritis. Doctors tend to look for this problem to diagnose the condition. In early stages, pannus can mainly be found in small joints, such as feet, wrists, and hands. Larger joints, such as the shoulders and knees, can be affected as well. Over time, it would release chemicals and fluids that would erode surrounding tissues.  [1]

What Is Rheumatoid Arthritis?

Rheumatoid arthritis is an autoimmune disease, which causes the immune system to mistakenly attack healthy body cells. This leads to inflammation in the affected parts. The condition mostly occurs to many joints at the same time, such as those in the knees, wrists, and hands. If left untreated, rheumatoid arthritis would lead to permanent complications, including deformity, lack of balance, and pain. Inflammation can spread to other parts of the body as well and cause more serious problems. These might include eyes, heart, and lung issues. [2]
