hemorrhage into a joint. Trauma is the most frequent cause of hemarthrosis. Hemarthrosis can be identified most clearly in the talocrural, anconal, and radiocarpal joints, and especially the knee joints. As a result of hemarthrosis the joint, after one or two hours, becomes swollen and painful, and movements in it are sharply limited; fluctuation can be felt upon palpation. Treatment for hemarthrosis includes rest, aspiration of the blood and application of an elastic bandage or removable plaster cast.
