*3.3.2.5 The medial circumflex femoral artery (MCFA)*

It is a collateral branch of the PFA that originates 1–2 cm from its proximal part, journeys medially, and then wraps itself around the femoral diaphysis to give an ascending branch and a transverse branch that anastomoses with their counterparts of the LCFA.

Nerve structures that are at risk in hip arthroscopy are the femoral (FN), the sciatic nerve (SN), the lateral femorocutaneous nerve (LFCN), and the superior gluteal nerve (SGN).
