typical clinical features of intermittent hydrarthrosis
Intermittent hydrarthrosis is characterized by recurrent joint effusions occurring at regular intervals. Men and women are equally affected. The episode may parallel menses in women and resolve after menopause. The knee or another large joint develops an effusion over 12 to 24 hours with no or minimal discomfort or signs of inflammation. Attacks last for 3 to 5 days. There are no systemic symptoms. The recurrent episodes may occur lifelong. No treatment is proven to prevent or abort attacks, although low-dose colchicine has been used with success in some patients.
