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 . </P> <P> The deepest (most anterior) structure in the fossa, the popliteal artery runs in close proximity to the joint capsule of the knee as it spans the intercondylar fossa . Five genicular branches of the popliteal artery supply the capsule and ligaments of the knee joint . The genicular arteries are the superior lateral, superior medial, middle, inferior lateral, and inferior medial genicular arteries . 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 . </P>
