What is the main difference between osteoarthritis and rheumatoid arthritis?

See below. Rheumatoid arthritis is a destructive, inflammatory arthritis that is caused by the production of antibodies in your body that attacks the joint lining called the synovium. Osteoarthritis is not an autoimmune condition and is generally thought to be a condition in which degeneration of a joint outstrips its ability to heal itself. There is also inflammation. Osteoarthritis is generally less severe.
Local vs genl infl. Osteoarthritis is "wear and tear" on joints. Rheumatoid is a generalized inflammatory condition that affects joints and other organ systems; autoimmune in nature; chronic disease that can cause multiple and serious sequelae. Treatment available; should see rheumatologist (medical specialist in joint and rheumatic diseases).
See answer. Osteoarthritis is generally thought to be caused by "wear and tear" of joints with destruction due to mechanical causes. Rheumatoid arthritis is caused by damage to the joint from the immune system. Treatments and prognosis are very different between the two.

Which is the main difference between rheumatoid arthritis, osteoarthritis, and gouty arthritis?

Many... Ra affects everything in the body by chronic inflammation, joint stiffness, related diseases. It may cause severe deformity and contracture of the toes and fingers. Gout can cause joint pain acutely and gradually create enough joint changes to produce chronic pain as well. Kidney function is what is treated as the root cause of gout. Osteoarthritis is mainly the wear and tear process in joints.
All different. Osteoarthritis is a 'wear and tear' type of disease. Gout is due to having too much uric acid in your body. Ra is your immune system attacking your joints.

What's the main difference between rheumatoid arthritis, osteoarthritis, and gouty arthritis?

See below. Put in simplest terms: osteoarthritis is the "normal arthritis" we get from wear and tear where cartilage wears out. Cartilage allows joint to move smoothly without bones grinding against each other. Rheumatoid arthritis is a inflammatory arthritis believed to be the result of an autoimmune disorder. Very painful and destructive, affecting multiple joints. Gout is result of uric acid in a joint.
Different causes. Gouty arthritis- due to an increase of uric acid production or underexcretion. Typically affects big toe joints, as well as the mid foot, ankle, knees, wrist. Diagnosis confirmed by uric aicd crytals in the joint. Presents itself by painful acute episodes, typically at night. Osteo- bone on bone- which cause inflammation in and around the joint. Ra- chronic persistent pain, .

What is the difference between osteoarthritis and rheumatoid arthritis?

Aging vs. Attacking. Osteoarthritis is often referred to as "wear and tear" arthritis that develops as we age. Rheumatoid arthritis is an autoimmune disorder in which the body attacks and destroys its own joints.
Inflammation. Rheumatoid arthritis is caused by inflammation in joints and that inflammation can lead to destruction and other chronic problems. Osteoarthritis is not typically considered an inflammatory disease. It is mostly associated with the aging process, post traumatic joint injuries, or what we would consider the arthritis resulting from wear and tear., treatments also differ dramatically.

What is the big difference between osteoarthritis and rheumatoid arthritis?

Wear&tear v inflamma. Think of osteoarthritis (OA) as result of wear & tear that comes w/aging & repetitive injury. Check out http://www. Mayoclinic. Org/diseases-conditions/osteoarthritis/basics/definition/con-20014749 for more info. Compare that to rheumatoid arthritis which is much less common inflammatory disorder. Http://www. Mayoclinic. Org/diseases-conditions/rheumatoid-arthritis/basics/definition/con-20014868.

What is the difference between rheumatoid arthritis and severe degenerative osteoarthritis?

Overuse / Immune sys. Rheumatoid arthritis is caused by one's immune system attacking the joint cartilage, so usually in multiple joints at once. Degenerative arthritis or osteoarthritis is from traumatic overuse. Actual overuse by repetitive normal motions is unusual. A knee joint will run thousands of miles over 70 years if the knee is never "twisted" injured. Not using a joint enough leads to osteoarthritis!

What is the difference between RA (rheumatoid arthritis) and oa (osteoarthritis)?

Too many to mention. Ra is an autoimmune disease characterized by inflammation of large and small joints in all extremities. Oa is more of a wear and tear type of arthritis. There are numerous other differences.

What is the difference between rheumatoid arthritis and severe degenerative osteoarthritis. Their treatments?

Many differences. Rheumatoid arthritis typicall affects small joints of the hands and feet, is much more painful and causes stiffness of the joints. Degenerative joint disease, also called osteoarthritis is disease of the weight bearing joints like knees and hips and causes low to moderate degree of pain and it often occurs after 50 yrs of age.

What are the differences between rheumatoid arthritis and severe degenerative osteoarthritis?

Wear and tear. Osteoarthritis is wear and tear on joints causing mechanical damage, especially to cartilage. There is bony overgrowth and ultimately joints become bone on bone. This is extremely painful and often requires joint replacement surgery. Pain of OA has an inflammatory component that responds to NSAIDs. RA is the opposite. Autoimmune inflammation causes the synovial tissue to eat into cartilage and bone.
