Rheumatoid arthritis (RA) and osteoarthritis (OA) are two common types of arthritis, both causing pain and joint damage but differing significantly in nature. RA is an autoimmune disease, where the immune system attacks healthy joint tissues, primarily affecting the synovium, the lining of the joints. This can lead to inflammation that impacts multiple joints and other parts of the body. In contrast, OA is a degenerative joint disorder, marked by the breakdown of cartilage that caps the bones in joints. It’s typically associated with aging and wear and tear of the joints.
The onset and progression of these conditions also vary. OA develops gradually, often affecting joints like the knees, hips, and those in the hands and spine. RA, on the other hand, can worsen rapidly over weeks or months, usually affecting the hands and wrists, and often involves symmetrical joint pain.
Despite these differences, both RA and OA can cause significant discomfort and disability. Diagnosis, prognosis, and treatment for RA and OA are distinct. RA treatments often involve managing the autoimmune response, while OA treatments focus on relieving symptoms and improving joint function.
