Hemarthrosis

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 take a medicine (called a blood thinner) that prevents blood clots. 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.
