Anterior compartment of thigh Anterior compartment of thigh The anterior compartment of thigh contains muscles which extend the knee and flex the hip. The anterior compartment is one of the fascial compartments of the thigh that contains groups of muscles together with their nerves and blood supply. The anterior compartment contains the sartorius muscle (the longest muscle in the body) and the quadriceps femoris group, which consists of the rectus femoris muscle and the three vasti muscles – the vastus lateralis, vastus intermedius, and the vastus medialis. The iliopsoas is sometimes considered a member of the anterior compartment muscles, as is the articularis genus

This crossing marks the point in which the vessel changes its name to popliteal artery. As with any other fascial compartment, the posterior compartment of thigh can develop compartment syndrome when pressure builds up inside it, reducing the ability of arteries to transport blood to muscles and nerves. In acute cases, this is most frequently a consequence of trauma. Posterior compartment of thigh The posterior compartment of the thigh is one of the fascial compartments that contains the knee
