Hemarthrosis (or haemarthrosis, plural h(a)emarthroses) is a bleeding into joint spaces.

Causes

It usually follows injury but occurs mainly in patients with a predisposition to hemorrhage such as those being treated with warfarin (or other anticoagulants) and patients suffering from hemophilia.

It can be associated with knee joint arthroplasty.^[1]

Treatment

In hemophilia it may occur spontaneously, and recurrent hemarthroses are a major cause of disability in that patient group due to hemophilic arthropathy, requiring synovectomy, joint replacement^[2] and increased medical therapy to prevent further bleeding episodes, although it is controversial whether clotting factor administration adequately prevents hemarthroses.^[3]
