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.
The anterior tibial artery is a branch of the popliteal artery. [1] It originates at the distal end of the popliteus muscle posterior to the tibia. The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane.
The middle genicular artery is a small branch of the popliteal artery that originates inferior or distal to both the superior genicular arteries as well as the sural arteries. Inferior or distal to the origins of the superior and middle genicular arteries are the two inferior genicular arteries: Medial inferior genicular artery
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle.It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
anterior tibial artery. post. tibial recurrent artery; ant. tibial recurrent artery; muscular branches; anterior medial malleolar artery; anterior lateral malleolar artery; Dorsalis pedis artery; posterior tibial artery. fibular artery (sometimes from popliteal artery) communicating branch to the anterior tibial artery
This is the most common configuration of the origins of these arteries, however, many other anatomical variations exist. [ 1 ] The vessel here described as the tibiofibular trunk may alternately be regarded as the initial portion of the posterior tibial artery, with the fibular artery instead regarded as its branch.
It arises from the anterior tibial artery, as soon as that vessel has passed through the interosseous space. It ascends in the tibialis anterior muscle , ramifies on the front and sides of the knee-joint , and assists in the formation of the patellar plexus by anastomosing with the genicular branches of the popliteal , and with the highest ...
The circumflex fibular artery (circumflex fibular branch, circumflex branch of posterior tibial artery, or circumflex peroneal branch of posterior tibial artery) is a branch of the posterior tibial artery which supplies blood to the knee. [1] The artery branch of the anterior tibial artery, at its initial (or superior) segment, winds around the ...
