Popliteal artery

Popliteal artery is a major blood vessel in the human body that is responsible for supplying blood to the knee region, lower leg, and foot. It is a continuation of the femoral artery and is located in the popliteal fossa at the rear of the knee.

Anatomy

The popliteal artery begins at the opening in the adductor magnus muscle located at the distal portion of the femur, where the femoral artery ends. It extends to the lower border of the popliteus muscle, where it continues as the anterior tibial artery.

The popliteal artery is the deepest structure within the popliteal fossa, and is located midway between the medial and lateral condyles of the femur and tibia.

Branches

The popliteal artery has several branches, which can be grouped into two categories: muscular and cutaneous. The muscular branches supply the gastrocnemius, soleus, plantaris, and popliteus muscles. The cutaneous branches, also known as the sural arteries, supply the skin over the popliteal fossa.

Clinical significance

The popliteal artery is of clinical significance due to its location and the potential for injury. It is susceptible to aneurysm, which can lead to ischemia or gangrene if not treated promptly. It can also be affected by atherosclerosis, leading to peripheral artery disease.
