Bleeding into a joint or joint cavity, causing pain and swelling of the joint area; may result from injury or certain diseases (e.g., hemophilia).
Blood in the joint cavity from blunt trauma or penetrating wound, or occurring spontaneously in hemophiliac patients.
The presence of blood within a joint, usually the result of a moderately severe injury that causes bleeding into the joint. In hemarthrosis, the blood accumulates in the joint within a few hours of the injury, and the joint becomes swollen, stiff, and painful. The accumulation of blood suggests that one of the joint elements, for example, the ligament or joint capsule, has been damaged. Hemarthrosis may also occur spontaneously in people who have a blood clotting disorder, such as hemophilia, or people who are taking blood-thinning medication. Cells in the joint capsule will slowly absorb any remaining blood. A large hemarthrosis may require aspiration, in which a fine needle is used to draw the fluid out of the joint.
Joint pain and swelling caused by bleeding into a joint. This may follow injury or may occur spontaneously in a disease of the blood, such as hemophilia. Treatment is by immobilization, cold compresses, and correction of the blood disorder (if present). Removal of blood from the joint may relieve the pain.
