The anterior tibial artery is the main arterial supply of the anterior compartment of the leg.
While still in the posterior compartment of the leg, the anterior tibial artery gives off the:
- posterior tibial recurrent artery
- circumflex fibular artery
The anterior tibial artery passes in front of the ankle joint and continues as the dorsalis pedis artery onto the dorsum of the foot lateral to the tendon of the extensor hallucis longus and medial to the extensor digitorum longus and deep peroneal nerve.
- anterior tibial recurrent artery: arises immediately, passes upward in the tibialis anterior muscle to anastomose with lateral genicular branches (of the popliteal artery) at the knee
- muscular branches
- perforating branches: pass behind extensor digitorum longus, piercing the deep fascia and supplying the skin of the anterior leg
- anterior medial malleolar artery: anastomoses with the medial malleolar branch of the posterior tibial artery
- anterior lateral malleolar artery: anastomoses with the perforating branch of the peroneal artery
- high-origin/high-division anterior tibial artery 4
- origin above proximal to the popliteus muscle belly
- prevalence ~3%
- aberrant anterior tibial artery 5
- high-origin anterior tibial artery that courses between the posterior tibial cortex and popliteus
- prevalence ~2.5%
Recognition of high-origin and aberrant anterior tibial arteries is important to reduce the risk of inadvertent vascular injury, during knee surgery (e.g. arthroplasty, high tibial osteotomy, lateral meniscal repair, posterior cruciate ligament reconstruction) 4,5.
