Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Arthritis is a clinical finding of persistent joint swelling or painful restriction of joint movement. Arthralgia is pain in a joint, with or without inflammation. Thus, a patient with arthralgia will not necessarily have arthritis, nor does a patient with arthritis always have arthralgia. There are many causes of arthritis and arthralgia in children, and this section will be limited to the chronic arthritides of childhood that have no known cause.
