Osteoarthritis vs. Rheumatoid Arthritis: Key Differences in Cause and Progression
Neither osteoarthritis (OA) nor rheumatoid arthritis (RA) is universally “worse”—both cause significant discomfort and disability. They differ in cause and progression.
Osteoarthritis (OA)
- Most common arthritis type
- Caused by cartilage wear and tear
- Typically affects knees, hips, hands, spine
- Pain and stiffness worsen over time
- Primarily affects cartilage and bones
Rheumatoid Arthritis (RA)
- Autoimmune disease
- Immune system attacks joints
- Can affect other organs and systems
- Causes inflammation and joint damage
- May lead to additional systemic complications
Both significantly impact quality of life. Treatment depends on severity, overall health, and patient preferences.
