Posterior tibial recurrent artery

{{{Name}}}

Latin	arteria recurrens tibialis posterior

The posterior tibial recurrent artery is a small artery in the lower limb that plays a role in the vascular supply to the knee joint and surrounding structures. It is a branch of the posterior tibial artery, which is one of the major arteries of the leg.

Anatomy

The posterior tibial recurrent artery arises from the posterior tibial artery shortly after its origin from the popliteal artery. It travels superiorly and medially, coursing towards the knee joint. This artery is involved in the anastomosis around the knee, contributing to the blood supply of the popliteal fossa and the structures within it.

Branches

The posterior tibial recurrent artery does not typically have named branches, but it participates in the formation of the genicular anastomosis, which is a network of vessels that supply the knee joint.

Function

The primary function of the posterior tibial recurrent artery is to supply blood to the knee joint and the surrounding soft tissues. It plays a crucial role in maintaining the vascular integrity of the knee, especially during movements that require increased blood flow, such as flexion and extension.

Clinical Significance

The posterior tibial recurrent artery, although small, can be significant in certain clinical scenarios. It may be involved in collateral circulation in cases of arterial occlusion in the lower limb. Understanding its course and connections is important in surgical procedures involving the knee and the lower leg.
