Inferior Lateral Genicular Artery, Posterior View

Description

Posterior to the knee joint, the inferior lateral genicular artery courses transversely around the lateral aspect of the proximal tibia, passing deep to the lateral head of gastrocnemius and near the fibular (lateral) collateral ligament as it approaches the lateral tibial condyle. Distally, it contributes to the genicular anastomosis along the posterior capsule, with branches that arc medially toward the popliteal fossa while smaller arterioles track along periosteum and capsular attachments. Articular cartilage caps the femoral condyles superiorly and the tibial plateau inferiorly, framing the vascular network against the osseous contours. Blue ligamentous elements outline key stabilizers adjacent to the vessel. Genicular arteries matter when you are planning around the posterior knee. Arthroscopic posterolateral portal placement, posterior capsular releases, and lateral meniscal repairs can all come close to the inferior lateral genicular artery and its capsular branches, a known source of postoperative hemarthrosis or pseudoaneurysm when injured. The posterior view also clarifies why collateral flow often persists after segmental popliteal artery compromise, since the inferior lateral genicular participates in the periarticular bypass routes that maintain distal perfusion. Orthopaedic anatomy courses and sports medicine teaching files use this angle to connect surface portals and deep capsular anatomy to real vascular consequences. It also fits operative atlases for knee arthroscopy and posterolateral corner reconstruction, where labeling the inferior lateral genicular artery helps authors explain safe dissection planes and hemostasis.
