Difference between arthritis and rheumatoid arthritis
Arthritis is typically osteoarthritis, a chronic inflammation characterized primarily by degenerative changes in joint cartilage, followed by bone proliferation, making it a chronic disease. Early pathological changes include alterations in joint cartilage, such as subchondral bone extrusion, followed by changes in the muscles surrounding the periosteum and joint capsule. Early radiographic examinations can provide a definitive diagnosis. Its symptoms primarily manifest as pain. For rheumatoid arthritis, it generally presents as morning stiffness and joint swelling and pain more severe than in the surrounding area, which can essentially confirm a diagnosis. It usually affects large joints such as the knee, shoulder, or wrist joints, typically presenting as migratory pain. A definitive diagnosis can usually be made by testing for rheumatoid factor, with an anti-O level exceeding 500 units. Additionally, there may be a slight increase in white blood cells, accelerated erythrocyte sedimentation rate, and elevated C-reactive protein. Examination of the synovial fluid shows increased white blood cells and neutrophils. In such cases, using anti-rheumatic drugs might suffice, but it’s also crucial to ensure rest and local heat application. These two types of arthritis fundamentally differ.
