The popliteal artery is located deeper, adjacent to the popliteal surface of the femur and the posterior part of the knee capsule. It runs obliquely outward along the outer edge of the semitendinosus muscle to the level of the femoral condylar fossa in the middle of the posterior knee, and then vertically downward to the inferior edge of the popliteal muscle, where it divides into the anterior tibial artery and the posterior tibial artery. The former enters the anterior region of the calf via the superior border of the interosseous membrane, while the latter goes to the posterior region of the calf via the deep surface of the tendon arch of the hallux valgus muscle. In addition to the muscular branches of this artery, there are five articular branches, namely the superior medial and lateral knee arteries, the middle knee artery and the inferior medial and lateral knee arteries, which all participate in the arterial network of the knee. It is located deeper, adjacent to the popliteal surface of the femur and the posterior part of the knee capsule. It runs obliquely outward along the lateral border of the semitendinosus muscle to the level of the femoral condylar fossa in the middle of the posterior knee, and then vertically downward to the inferior border of the popliteal muscle, where it divides into the anterior and posterior tibial arteries. The popliteal artery may be weakened or absent in the event of a popliteal aneurysm and may be injured in the event of a supracondylar femoral fracture.
