Anatomic concerns also include branches from the femoral innervated muscles for whom trajectories are not clear, relative variability in innervation patterns to the anterior capsule in the presence of an accessory obturator nerve, accessory femoral nerve or superior gluteal nerve branches, the possibility of articular branches that start more inferiorly along the course of the femoral nerve and run with vessels, and a scenario where one common trunk supplies the joint, vessels, and muscles.

Its advantage over the more traditional femoral nerve block is that it can be combined with blockade of the sciatic nerve to anesthetize the entire lower limb (Table 3).
The sheath accompanies the femoral nerve to just below the inguinal ligament.
Blockade of this terminal branch of the femoral nerve is usually combined with a sciatic nerve block for procedures of the leg (distal to the knee) or a popliteal block for procedures involving the foot and ankle (Table 3).
The last of the five nerves, the saphenous nerve, is a terminal branch of the femoral nerve and it supplies the proximal, medial aspect of the foot.
All femoral nerves had average branch-free lengths >1.
Figure 2 compares the fascicular arrangement of the femoral nerve just proximal to branching between all four femoral nerves.
Figure 4 shows the distribution of individual fascicular diameters from the four fully mapped compound femoral nerves.
We could also expect nerve dimensions to be larger in male subjects, who constituted the individuals undergoing surgical exposure of their femoral nerves, while the cadaveric specimens were female.
The femoral artery was first palpated below the inguinal ligament and the femoral nerve was then located about 0.
We found that the continuous 3-in-1 femoral nerve block has an opioid-sparing effect and it is associated with more favourable patient satisfaction scores, although it is not associated with better pain scores.
Therefore continuous 3-in-1 femoral nerve blocks may be considered more desirable post TKA (11, 18).
