A Frontal projection digital subtraction angiography revealed extensive hypervascular synovium supplied by branches of the genicular arteries (white arrows) at the superomedial, inferomedial, and superolateral compartments (white circles) about the total knee replacement prosthesis. B Completion angiography after genicular artery embolization demonstrated subtotal devascularization with mild residual synovial blush (white circles) at the inferomedial compartment. C Selective angiography and embolization of the articular branches of the recurrent anterior tibial artery (white arrows) supplying the lateral joint space. D Completion angiography after genicular artery embolization demonstrated total devascularization
