Hip arthroscopy has recently become an important minimally invasive diagnostic and therapeutic tool. The indications for hip arthroscopy are expanding, and their utility continues to be better defined in the literature. This technical procedure faces typical technical problems owing to joint anatomy; narrow depths, strict maneuvering space, and proximity to at-risk structures have led to continuous improvements in surgical access and instrumentation over the past decades. This also explains the difficulties that most of the time we face in performing hip arthroscopy and the long learning curve typical of this surgery. Understanding the bony anatomy and soft tissues surrounding the hip is a basic prerequisite for performing safe and effective hip arthroscopy. In addition, individualization of the correct entry points or portals represents the first step toward an optimal approach to the hip. The purpose of this chapter is to provide a detailed description of the normal intra-articular anatomy of the hip that orthopedic surgeons can expect to encounter during hip arthroscopy. In this way, pathology can be distinguished from a normal anatomy.
