Digital subtraction angiography images of the right knee joint of a 62-year-old participant with predominantly medial knee osteoarthritis. (A) Peri-interventional image of the popliteal artery. Yellow arrow indicates the descending genicular artery, and blue arrow indicates the medial inferior genicular artery. (B, C) Selective preinterventional images show hypervascularity of two branches of the genicular artery: the (B) descending genicular artery (arrow) and the (C) medial inferior genicular artery (arrow). (D, E) Selective postinterventional images obtained after embolization with rapidly resorbable gelatin-based microspheres. Complete elimination of the blush is observed, with preserved perfusion of the proximal arterial segments.
