Medial aspect of the infrapatellar fat pad. Arteries arising from the inferior medial genicular artery. (a1) the main vessel gives off a proximal (a2), a distal (a3), a diagonally converging branch toward the patellar apex (a4) and a horizontal branch (a5). The latter is one of the strongest branches of the deep vascular level and forms an anastomosis with that of the lateral side. Except of (a5), all vessels are located in the intermediate vascular layer. P: patella.
