The genicular arteries (from Latin geniculum, "knee") are six arteries in the human leg, five of which are branches of the popliteal artery, that anastomose in the knee region in the patellar network or genicular anastomosis.
[1] They supply blood to the patella, together with contributions from the descending genicular artery, anterior tibial recurrent artery, and descending branch of lateral circumflex femoral artery.
Five genicular arteries branch from the popliteal artery to form a network around the knee, the genicular anastomosis.
The anastomosis provides collateral circulation in the event of damage to the region.
Inferior or distal to the origins of the superior and middle genicular arteries are the two inferior genicular arteries: The descending genicular artery is the only one to branch from the femoral artery.
