The 2010 ACR/EULAR classification criteria define 'definite rheumatoid arthritis' by confirmed synovitis in at least one joint, absence of a better alternative diagnosis, and a total score of 6 or more out of 10 across four domains: number and site of involved joints (0-5), serology (0-3), acute-phase response (0-1) and symptom duration (0-1). This is the formal boundary between inflammatory arthritis and degenerative joint disease.

DOI: 10.1002/art.27584. 2. The 2025 EULAR update recommends methotrexate, ideally combined with short-term glucocorticoids, as initial therapy for rheumatoid arthritis, within a treat-to-target strategy across conventional synthetic, biological and targeted synthetic DMARDs - a disease-modifying drug pathway that has no counterpart in osteoarthritis and which belongs to rheumatology.

DOI: 10.1016/j.ard.2026.01.023. 3. The 2020 ACR gout guideline issued 42 recommendations including 16 strong ones: start urate-lowering therapy for anyone with tophaceous gout, radiographic damage from gout or frequent flares; allopurinol first-line including in moderate-to-severe chronic kidney disease; low starting doses; and treat-to-target dose titration to a serum urate below 6 mg/dL. Gout is treatable to target in a way osteoarthritis is not.

DOI: 10.1002/acr.24180. 4. In the Framingham Osteoarthritis Study, 710 people over 50 with NO radiographic evidence of knee osteoarthritis underwent knee MRI: 89% had 'any abnormality'. Osteophytes appeared in 74%, cartilage damage in 69% and bone marrow lesions in 52%. Prevalence of at least one abnormality was 90-97% in painful knees and 86-88% in painLESS knees.

DOI: 10.1136/bmj.e5339. 5. The 2019 ACR/Arthritis Foundation guideline makes STRONG recommendations for exercise, weight loss in people with overweight or obesity, self-efficacy and self-management programmes, tai chi, cane use, hand orthoses for first-CMC joint OA, tibiofemoral bracing, topical NSAIDs for the knee, oral NSAIDs and intra-articular glucocorticoid injections for the knee; acupuncture, thermal modalities, radiofrequency ablation, acetaminophen, duloxetine and tramadol are only conditional.

X-rays reveal changes in bone and joint space. Blood tests can check for immune activity, gout, or infection. ## Is there a blood test for arthritis? There isn't one blood test for every type. Antibody tests and signs of swelling in the blood can support a check for rheumatoid disease. A uric acid test can help when gout is possible. The exam and your symptoms still matter. ## What is the difference between degenerative joint disease and arthritis? Degenerative joint disease usually means osteoarthritis. It often brings gradual change in the whole joint. Arthritis is a larger family that also includes rheumatoid disease, gout, and other causes. The name matters because each type can call for different care. ## What is the difference between osteoarthritis and rheumatoid arthritis? Osteoarthritis often causes soreness with use and brief stiffness after rest. Rheumatoid disease comes from the immune system. It can bring long morning stiffness and matching swollen joints. If you have those signs, don't rely on home care alone. ## What is a red flag of rheumatoid arthritis? Watch for swelling that stays in the same small joints on both sides. Morning stiffness that lasts a long time also matters. Arrange a medical visit if those signs continue. A single hot joint with fever is different and needs urgent care. ## What type of arthritis is most painful? No type always hurts more than every other type. Gout can start suddenly, while hip osteoarthritis may make each step hard. Tell your provider how the soreness starts and which actions worsen it. Those details help more than ranking one name above another. ## Where can I get arthritis treatment in Phoenix? QC Kinetix has Phoenix-area clinics for ongoing joint soreness.
