Circumflex fibular artery

The circumflex fibular artery (Latin: arteria circumflexa fibularis) is a branch of the posterior tibial artery. It ascends to the popliteal fossa, curves around the head of the fibula and participates in forming the patellar network. The circumflex fibular artery contributes to supplying the knee joint and the muscles around it.

The patellar network is located around and above the patella. The blood vessels contributing to this network are as follows: inferior medial and superior medial genicular arteries, inferior lateral and superior lateral genicular arteries, descending genicular artery, descending branch of the lateral circumflex femoral artery, and the anterior tibial recurrent artery. The patellar network supplies the knee joint and provides collateral circulation to the leg.
