Of the more than 100 types of arthritis, two account for the majority of cases-osteoarthritis and rheumatoid arthritis. While both conditions produce joint pain, the causes differ. And only rheumatoid arthritis has disease-modifying treatment. While there is still no cure, many people can achieve a state of remission or at least low disease activity. Remission from a chronic disease essentially means the absence of signs and symptoms. For rheumatoid arthritis, there are specific criteria for defining the states of remission, low-disease activity, moderate disease activity and high disease activity.
