The peritrochanteric space is a complex and constrained space and is often a source of commonly encountered lateral hip pain. In previous times, clinicians encountered difficulty in treating conditions encompassing this space in the past. However, modern imaging techniques have led to a better understanding of different pathologies that can be found in the peritrochanteric space. Consequently, operative and non-operative strategies have been developed and this has added to global adoption of endoscopic techniques such as hip arthroscopy [5].

This exponential growth in procedure numbers has been facilitated by educational courses, societies dedicated to hip preservation and refined surgical equipment that has helped reduce surgical technical challenges [1]. Even though, the results of recent randomized controlled trials have validated the efficacy of hip arthroscopy for conditions that are commonly treated such as femoroacetabular impingement (FAI) [2,3,4] this field is not stagnating! Arthroscopic surgery’s next challenge is tackling conditions in the peritrochanteric space (those not in the typical central compartment).

But, now comes the hard part of providing the evidence. In this special edition, members of the ESSKA Hip Arthroscopy Committee provide scoping reviews that combine the best of expertise and evidence-based approaches to treat peritrochanteric space disorders. While the evidence for treating these conditions is still emerging, input from renowned experts is needed. Thus, these papers serve as guides to approaching these challenging clinical scenarios. They collectively provide a starting point for the next round of clinical investigations that will continue to propel the field of hip preservation forward.
