Study Notes

Nerve Supply and Muscular Functions

Tensor fasciae latae is mainly supplied by the superior gluteal nerve.
Anterior cruciate ligament tightens during the 'screw-home' mechanism when extending the knee.
Tibialis anterior is innervated by the deep peroneal nerve and is not supplied by the tibial nerve.

Knee Joint Anatomy

Intrasynovial structures in the knee joint do not include the oblique popliteal ligament, the tendon of popliteus, or the menisci; the anterior cruciate ligament is also not intrasynovial.
The knee joint's 'screw-home' movement involves the anterior cruciate ligament.

Adductor Canal

Located in the thigh, the adductor canal contains the femoral artery and saphenous nerve.
The canal does not contain muscular nerves and has adductor longus forming its roof.

Veins and Lymphatics

The great saphenous vein joins the femoral vein inferior to the inguinal ligament and travels with the saphenous nerve.
Superficial inguinal nodes consist of about 15 nodes that drain lymph from the lower limb.

Femoral Artery Anatomy

The profunda femoris artery arises from the anteromedial aspect of the femoral artery and supplies deep structures of the thigh.
The medial circumflex femoral artery is key in the trochanteric anastomosis along with the superior and inferior gluteal arteries.

Muscles and Bursae

Gluteus maximus forms the gluteal fold, comprises four bursae beneath it, and primarily receives blood from the inferior gluteal artery.
In the hamstring compartment, semitendinosus lies superficial to semimembranosus, and the long head of biceps femoris arises from the lateral facet of ischial tuberosity.

Fascia and Tracts

Fascia lata attaches inferiorly to tibial condyles and head of the fibula, continuous below and reinforced by quadriceps tendon.
The iliotibial tract lies lateral to tensor fascia latae and attaches superiorly to the iliac crest.

Femoral Triangle Components

Muscles in the floor of the femoral triangle include iliacus, psoas, and pectineus, while adductor magnus is not present in this region.

Miscellaneous

The sciatic nerve passes down deep to muscles like quadratus femoris and piriformis; it separates into tibial and common peroneal components near the hip joint.
The medial intermuscular septum separates the adductor compartment from the posterior compartment of the thigh.
