Dissection of knee
Superficial vessels and nerves of left knee; patellar retinaculum; medial view
The tela subcutanea has been dissected to display the superficial blood vessels and nerves on the medial aspect of the knee. The great saphenous vein (9) has been divided and removed to permit better exposure of the branches of the saphenous nerve. The fascia lata (11) has been retained in the area immediately anterior to the medial intermuscular septum. Elsewhere the fascia has been cut away to expose underlying muscles and tendons that pass medial to the knee joint.
