The relative and absolute blood contents in the knee joint after intraarticular injections were determined using a biochemical joint function test. Normally, only minimal amounts of blood leak into the joint cavity, but in a few cases greater quantities were found, unnoticed at the time of injection. Intraarticular injections should be done only by a specialist.
