Rheumatoid arthritis (RA) and osteoarthritis (OA) are two common types of arthritis, each causing pain and joint damage, yet they are distinctly different diseases. RA is an autoimmune disease, where the body’s immune system mistakenly attacks its own tissues, primarily affecting the synovium – the linings of joints. In contrast, OA is a degenerative joint disease characterized by the wearing away of cartilage that caps the bones in joints.
Despite their similarities, RA and OA have several differences. RA is recognized as a more disabling type of arthritis compared to OA, which is the most common form. The primary distinction lies in the underlying nature of each disease. RA’s autoimmune nature leads to fluctuating symptoms and unique complications in each patient, often causing confusion with OA symptoms. Conversely, OA is a result of mechanical wear and tear on joints.
X-rays are a valuable tool in differentiating RA from OA. In OA, X-rays typically show less space between the bones, whereas in RA, there is more noticeable bone erosion. However, it’s important to note that in the early stages of either condition, X-rays can appear normal.
