Here we present 4 cases of Knee Sub-Acute Hemophilic Arthropathy according to clinical, X-ray and ultrasound aspects. The X-ray images show subtle changes in the early phases of Hemophilic Arthropathy (HA). Ultrasound aspects are emphasized, which provided direct image of the synovial membrane at the knee anterior capsular recess. We discuss the potential ultrasound use as a marker of inflammatory activity.
