Left inferior lateral genicular artery (Arteria inferior lateralis genus)
Educational content only — not medical advice.
Anatomy
An arterial branch arising from the popliteal artery that passes above the fibular head deep to the fibular collateral ligament to supply the inferolateral knee joint and lateral meniscus. It forms an integral component of the rich collateral genicular anastomosis guaranteeing limb perfusion during deep knee flexion.
Clinical notes
Genicular arteries provide crucial collateral bypass pathways during popliteal artery entrapment or thrombosis; rupture of the middle genicular artery during ACL tears causes immediate tension hemarthrosis.
