Dr. Roger Wang on Arthritis

Why do people get arthritis?

The cause of arthritis remains unknown and in many cases it varies on the type of rheumatic disease. Genetics and family history play a big role, as does lifestyle (being overweight), trauma and excessive overuse or wear and tear of the joints. Infection, metabolic disturbances and hormones can also play a role in the development of arthritis.

What is the most common type of arthritis?

Osteoarthritis or degenerative joint disease is the most common type of arthritis.

What is the difference between rheumatoid arthritis and osteoarthritis?

Rheumatoid arthritis is a chronic disease or inflammatory disease. The inflammation of the lining or synovium of the joints results in long term joint damage.  Osteoarthritis is a chronic condition involving the break down of joint cartilage causing bones to rub against one another. This causes stiffness, pain and loss of movement.

Will cortisone injections relieve the pain associated with arthritis and how long do these shots last? 

Cortisone injections will work well in patients with osteoarthritis.  Usually the injections will relieve pain for up to three months, depending on the individual.
