THE SAPHENOUS NERVE
NOTES
Originates L2-4 Nerve roots
Passes through the femoral triangle,
Passes lateral to the femoral sheath,
Accompanies the femoral artery in the adductor canal
After piercing the deep fascia on the medial aspect of the knee, the nerve courses superficially down the anteromedial lower leg.
Infrapatellar branches supply innervation to the knee
It runs laterally alongside the saphenous vein, giving off a medial cutaneous nerve that supplies the skin of the anterior thigh and anteromedial leg.
It travels to the dorsum of the foot, medial malleolus, and the area of the head of the first metatarsal.
At the level of ankle, the saphenous nerve is found between the medial malleolus and the anterior tibial tendon, just lateral to the saphenous vein.
