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.Five genicular branches of the popliteal artery supply the capsule and ligaments of the knee joint.They participate in the formation of the periarticular genicular anastomosis, a network of vessels surrounding the knee that provides collateral circulation capable of maintaining blood supply to the leg during full knee flexion, which may kink the popliteal artery.[2] It exits the popliteal fossa under the fibrous arch of the soleus muscle.The middle genicular artery supplies the cruciate ligaments and the synovial membrane of knee joint.
