chronic synovitis


Also found in: Dictionary, Thesaurus, Encyclopedia.

chronic synovitis

Synovitis in which an undue amount of fluid remains in the cavity and the membrane itself is edematous. Prolonged inflammation causes thickening of the membrane and articular structures by plastic exudation and the formation of fibrous tissue, which increases joint dysfunction and exacerbates symptoms. The joint is weak but not esp. painful, except on pressure and sometimes not even then. Movements, esp. in extension, are restricted and generally attended by crepitus or creaking. Symptoms are well marked when the patient has an excess accumulation of synovial fluid (the amount of fluid depends on the joint involved and also on the patient's body build). Fluid can be removed with a needle and syringe and sent to the laboratory for analysis.
