Iron deposition in the synovial membrane and meniscal surface. There was no iron deposition in the Im-NS group (a). Iron deposition was observed in the synovium and on the meniscal surface, lasting until 8 weeks after administration in the Im-B group (b-d). F: Femur, S: Synovium, JS: Joint Space, M: Meniscus. Perls: Prussian blue staining. The black arrowheads indicate iron depositions. Scale bar = 100 μm
