At the posterior aspect of the knee? lies the popliteal fossa.  It is a diamond shaped\u2666\ufe0farea that holds several important nerves and vessels that travel from the thigh to the knee. In this snippet we will take a closer look at its borders and contents.  <\/p>\n\n\n\n

The popliteal fossa has 4 <\/strong>main borders made from posterior muscles and tendons of the leg and thigh; <\/p>\n\n\n\n

  1. Superomedial border<\/strong> = Tendons of semimembranosus with the semitendinosus superficial to it <\/li>
  2. Superolateral border<\/strong> = Tendon of biceps femoris <\/li>
  3. Inferomedial border<\/strong> = medial head of gastrocnemius <\/li>
  4. Inferolateral border<\/strong> = lateral head of gastrocnemius and plantaris <\/li><\/ol>\n\n\n\n

    The floor of this fossa is comprised of the posterior surface of the knee joint capsule, popliteus muscle and posterior femur. The roof contains popliteal fascia and skin.  <\/p>\n\n\n\n

    Within the popliteal fossa 4<\/strong> main neurovascular structures are seen traveling from the thigh to leg;  <\/p>\n\n\n\n

    1. Popliteal artery<\/strong>– deepest structure, continuation of femoral artery  <\/li>
    2. Popliteal vein-<\/strong> the small saphenous vein passes between the two heads of gastrocnemius to empty into popliteal vein <\/li>
    3. Tibial nerve<\/strong>– most superficial, branch of sciatic nerve <\/li>
    4. Common fibular nerve<\/strong>– most superficial, branch of sciatic nerve and travels along lateral margin of fossa <\/li><\/ol>\n\n\n\n

      You can use the mnemonic SAVNB <\/strong>(Serve And Volley Next Ball) <\/strong>to remember the popliteal fossa anatomy medial-to-lateral in arrangement. S<\/strong>emimembranosus, A<\/strong>rtery, V<\/strong>ein, N<\/strong>erve, B<\/strong>iceps femoris.  <\/p>\n\n\n\n

       Damage to this area from trauma can result in swelling known as a popliteal aneurysm. Meaning an artery has been dilated greater than 50% of its normal size. This is particularly dangerous in this area due to popliteal fascia being non-extensible. Thus, an aneurysm could affect the inner contents of the fossa. For instance, the tibial nerve could be compressed resulting in weakened\/absent plantar flexion, or paraesthesia of the foot and posterolateral leg. Luckily such conditions can be diagnosed by a professional health care provider by palpating the area ?\u200d\u2695\ufe0f?\u200d\u2695\ufe0f\u2695\ufe0f.  <\/p>\n\n\n\n
