haemarthrosis

Blood within a joint space. This can occur from injury or disease such as SCURVY or HAEMOPHILIA. There is pain, heat, swelling and muscle spasm. Such blood soon absorbs but repeated episodes cause damage and crippling deformity.

haemarthrosis

the presence of blood in a joint cavity. This may be the result of trauma or occur spontaneously, as in haemophilia. In sport haemarthrosis is most commonly seen in the knee joint where it is always indicative of significant injury such as cruciate (70% have an anterior cruciate tear) and/or collateral ligament injury, intra-articular fractures, meniscal tears or patellar dislocation. Blood accumulates in the joint within 1-2 h in a haemarthrosis compared to the slower (24+h) accumulation in a joint effusion. Early referral to a knee specialist is recommended because of the potential for intervention to prevent chronic joint damage.
