The MR findings at the examination of 16 knees in 9 hemophilie patients were reviewed. The hemophilie arthropathy was demonstrated in great detail. The state of the joint cartilage, menisci, posterior cruciate ligaments and synovial tissue could be assessed. The presence of intraarticular hemorrhage and cyst fluid in bone cavities was recorded. MRI may become a valuable tool for assessment of early treatment of hemophilie arthropathy.
