M25.0: Haemarthrosis

Haemarthrosis is a medical condition characterized by the presence of blood within a joint space. This typically occurs after a traumatic injury that causes damage to the blood vessels within the joint, resulting in bleeding. However, it can also occur spontaneously in individuals with certain blood disorders. The symptoms of haemarthrosis often include joint warmth, redness, swelling, pain, and a decreased range of motion. Affected individuals may also experience a feeling of tightness within the joint. As the condition progresses, continued bleeding can lead to an increased risk of permanent joint damage and the development of conditions such as arthritis. Haemarthrosis can occur in any joint in the body, though the knees, elbows, and shoulders are commonly affected.
