Hemarthrosis is the American spelling of haemarthrosis.

Knee swollen with haemarthrosis

Swollen knee secondary to haemarthrosis.



The blood is contained within the knee capsule, giving the haemarthrosis a balloon-like quality.


Bleeding inside the knee joint

Haemarthrosis may be a result of trauma, such as a torn cruciate ligament, or it may be a complication of knee surgery, such as a lateral release, where the blood vessels have not been sealed prior to release of the tourniquet.
