The saphenous nerve is also often damaged during vein harvest for bypass surgery and during trocar placement during knee arthroscopy. There appears to be occasional meaningful individual variation in the pathway of this nerve, such that the illustration of it done for Gray's Anatomy , for example, likely represents an unusual rather than usual ...
This nerve communicates above the knee with the anterior cutaneous branches of the femoral nerve; below the knee, with other branches of the saphenous; and, on the lateral side of the joint, with branches of the lateral femoral cutaneous nerve, forming a plexiform net-work, the plexus patellae.
The anterior branch runs downward on the sartorius, perforates the fascia lata at the lower third of the thigh, and divides into two branches: one supplies the integument as low down as the medial side of the knee; the other crosses to the lateral side of the patella, communicating in its course with the infrapatellar branch of the saphenous nerve.
Common fibular nerve (blue) - labeled as "peroneal nerve". Also Lateral sural cutaneous nerve. Saphenous nerve (pink), a branch of the femoral nerve. Superficial fibular nerve (yellow) - labeled as "superficial peroneal nerve". Also Medial dorsal cutaneous nerve. Sural nerve (brown). Also Medial sural cutaneous nerve.
It is a fine network of communicating nerve fibres. [2] It is formed by the anterior division of lateral femoral cutaneous nerve, terminal branches of the intermediate femoral cutaneous nerve, terminal branches of the medial femoral cutaneous nerve, and the infrapatellar branch of saphenous nerve.

Moving from superficial to deep structures, the roof is formed by: the skin. [1]the superficial fascia. [1] This contains the small saphenous vein, the terminal branch of the posterior cutaneous nerve of the thigh, posterior division of the medial cutaneous nerve, lateral sural cutaneous nerve, and medial sural cutaneous nerve.
The anterior branch supplies the anterolateral aspect of the thigh while the lateral branch supplies the lateral aspect of the gluteal region. [2] Femoral nerve and its terminal branches - The nerve enters the femoral triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove ...
It runs over the long head of the biceps femoris to the back of the knee. [citation needed] It pierces the fascia lata posterior to the knee. It then accompanies the small saphenous vein to about the middle of the posterior leg (i.e. lower leg). [2] Its terminal branches communicate with the sural nerve. [citation needed]
