Renal and Musculoskeletal Modifications | Nursing homework help
These two diseases have different pathophysiologies. OA only affects certain areas of the joint like the cartilage while RA can affect multiple parts such as synovial membranes, tendons and ligaments, bone tissue, and even the bones. OA causes gradual joint deterioration over time, while RA can lead to inflammation that leads to pain and swelling in a matter days or weeks. OA is not associated with fever or fatigue, but RA could cause extra-articular symptoms, such as rash or eye irritation.
