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.
