Rheumatoid arthritis (RA) and osteoarthritis (OA) are actually quite different, even though both affect the joints. RA is an autoimmune disease where the immune system attacks joint tissue, causing inflammation. OA is a degenerative condition caused by wear and tear on cartilage over time.
Here are some key differences:
- Pain pattern: RA pain is often worse in the morning or after rest, while OA pain tends to worsen later in the day after activity
- Symmetry: RA typically affects both sides of the body equally (e.g., both knees), while OA may only affect one side
- Morning stiffness: RA stiffness usually lasts more than 30 minutes; OA stiffness typically resolves within 30 minutes
- Joints affected: RA often starts in the small joints of the hands and feet, while OA commonly affects the neck, lower back, hips, and knees
- Beyond the joints: RA can affect other parts of the body like the eyes and heart; OA stays localized to the joints Treatment also differs significantly. RA is primarily managed with disease-modifying antirheumatic drugs (DMARDs) and biologics that target the immune system. OA is managed with over-the-counter pain relievers, cortisone injections, and physical therapies. DMARDs don't help with OA since it isn't an autoimmune condition.
