The saphenous nerve (long or internal saphenous nerve) is the largest cutaneous branch of the femoral nerve. It is derived from the lumbar plexus (L3-L4). It is a strictly sensory nerve, and has no motor function. It commences in the proximal (upper) thigh and travels along the adductor canal.
The medial cutaneous nerve, before dividing, gives off a few filaments, which pierce the fascia lata, to supply the integument of the medial side of the thigh, accompanying the long saphenous vein. One of these filaments passes through the saphenous opening; a second becomes subcutaneous about the middle of the thigh; a third pierces the fascia ...
The infrapatellar branch of saphenous nerve is a nerve of the lower limb. [1] The saphenous nerve, located about the middle of the thigh, gives off a branch which joins the subsartorial plexus. It pierces the sartorius and fascia lata, and is distributed to the skin in front of the patella.
Femoral nerve blocks are very effective. [3] During pelvic surgery and abdominal surgery, the femoral nerve must be identified early on to protect it from iatrogenic nerve injury. [4] The femoral nerve stretch test can be performed to identify the compression of spinal nerve roots. [5] The test is positive if thigh pain increases. [5]

The subsartorial plexus is formed by: the medial cutaneous nerve of the thigh (a branch of the femoral nerve). [1]the saphenous nerve (a branch from femoral nerve). [1]the cutaneous branch of anterior division of the obturator nerve.
It is formed by the divisions of the first four lumbar nerves (L1-L4) and from contributions of the subcostal nerve (T12), which is the last thoracic nerve. Additionally, the ventral rami of the fourth lumbar nerve pass communicating branches, the lumbosacral trunk, to the sacral plexus. The nerves of the lumbar plexus pass in front of the hip ...
The saphenous branch pierces the aponeurotic covering of the adductor canal, and accompanies the saphenous nerve to the medial side of the knee. It passes between the sartorius muscle and the gracilis muscle, and, piercing the fascia lata, is distributed to the integument of the upper and medial part of the leg, anastomosing with the medial inferior genicular artery.
