Hemarthrosis is bleeding into a joint. It often causes inflammation
and pain.
Hemarthrosis is more likely to occur in people with bleeding
disorders, such as hemophilia (a rare inherited condition), or in those who use
blood-thinning medication, such as warfarin. It also can develop after an
injury to a joint when blood vessels in the joint are also injured.
Treatment for hemarthrosis depends on the cause.
