The patellar network (circulatory anastomosis around the knee-joint, patellar anastomosis, genicular anastomosis, articular vascular network of knee [1] or rete articulare genus [2]) is an intricate network of blood vessels around and above the patella, and on the contiguous ends of the femur and tibia, forming a superficial and a deep plexus.
From here, wires and catheters can be directed anywhere in the arterial system for intervention or diagnostics, including the heart, brain, kidneys, arms and legs. The direction of the needle in the femoral artery can be against blood flow (retro-grade), for intervention and diagnostic towards the heart and opposite leg, or with the flow (ante ...
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. [1] Inferior or distal to the origin of the descending genicular artery are two superior genicular arteries: Medial superior genicular artery

It is the smallest branch of the lateral circumflex femoral artery and passes lateralward over the vastus intermedius, pierces the vastus lateralis, and winds around the femur, just below the greater trochanter, anastomosing on the back of the thigh with the medial femoral circumflex artery, the inferior gluteal artery, and the perforating ...
The descending genicular artery (also known as the highest genicular artery) arises from the femoral artery just before its passage through the adductor hiatus.. The descending geniculate artery immediately divides into two branches: [contradictory] a saphenous branch (which classically joins with the medial inferior genicular artery), and muscular and articular branches.

The fibular artery arises from the bifurcation of tibial-fibular trunk into the fibular and posterior tibial arteries in the upper part of the leg proper, just below the knee. It runs towards the foot in the deep posterior compartment of the leg, just medial to the fibula. It supplies a perforating branch to both the lateral and anterior ...
