The anterior tibial vein is located in the front compartment of the lower leg, and goes from the upper ankle joint to just above the crook of the knee. It carries blood up from the front, or anterior, section of the leg, to the popliteal vein; this vein then moves the deoxygenated blood from the joint of the knee and the thigh muscles back to the heart. The anterior tibial vein is accompanied by the anterior tibial artery along its entire length.
