Findings-There is evidence of significant synovial collection involving the knee joint distending the suprapatellar bursa with inhomogeneous appearance with septae & areas of haemosiderin deposition seen as signal suppression on GRE. There is evidence of erosive destruction involving the tibio-femoral & patello-femoral articulation. Secondary degenerative changes noted in the tibio-femoral & patello-femoral articulation with reduction in joint space. Areas of marrow edema noted in knees in relation to bones forming the knee joint appearing hyperintense on T2 fat sat images. Anterior cruciate ligament is not well seen. Posterior cruciate ligament is stretched but intact. Internal architecture of the knee is distorted with haemosiderin deposition in relation to synovium.
Opinion-Significant synovial collection involving the knee joint & suprapatellar bursa with extensive haemosiderin deposition, erosive arthropathy involving tibiofemoral & patellofemoral articulation with marrow edema involving the bones surrounding knee joint, distorted internal architecture of knee. Likely suggestive of sequelae of long standing hemarthrosis. Patient is a known case of hemophilia. Consistent with hemophilic arthropathy.
