Hemarthrosis (or haemarthrosis, plural h(a)emarthroses) is a bleeding into joint spaces.
Causes [edit]
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 with hemophilia.
It can be associated with knee joint arthroplasty.[1]
Treatment [edit]
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]
Complications [edit]
Up to a quarter of all severe ligament or capsular knee injuries leading to a haemarthrosis are associated with cartilage damage that can lead to progressive degenerative arthritis.[4]
