Explanation:Correct Option: A. The anterolateral portal is typically the first portal established in hip arthroscopy, placed just superior and anterior to the tip of the greater trochanter. The superior gluteal nerve courses approximately 4-5 cm proximal to this portal and is at risk if trocars or instruments are errantly directed proximally into the abductor musculature.
