Severe Hemophilic Arthropathy of the Knee: MRI Has Its Place.

Hemophilia is a congenital coagulopathy characterized by a deficiency of coagulation factors and the development of haematomas and haemarthrosis, either spontaneously or after minor trauma. Recurrent joint hemorrhage in hemophilia patients leads to progressive and degenerative arthropathy, which affects around 90% of patients with severe disease and contributes significantly to disease morbidity. Positive diagnosis is based on biology. Imaging, particularly MRI, plays an essential role in assessing the evolution and complications, especially osteoarticular complications. We report 2 cases of severe hemophilia A, who presented with almost identical clinical and radiological symptoms. The patients developed severe arthropathy with a course marked by recurrences of haemarthrosis.
