Background: Combined hip arthroscopy and periacetabular osteotomy (PAO) allows for treatment of intra-articular hip pathology with simultaneous correction of acetabular version and femoral head coverage in patients with symptomatic hip dysplasia. Currently, scant data is available to surgeons regarding optimal technique, sequence of repair, perioperative management, and the use of intra-abdominal monitoring in patients undergoing these combined procedures. The purpose of this study is to describe a two-surgeon, muscle-sparing, approach for sequential hip arthroscopy and PAO for the treatment of adults with acetabular dysplasia and concomitant intra-articular hip pathology. Methods: In this article, we present the indications for combined hip arthroscopy and PAO, in addition to patient set-up and positioning. A detailed discussion of hip arthroscopy and a muscle sparing PAO techniques are then presented, with overview of a novel intra-abdominal pressure monitoring technique and post-operative rehabilitation protocol. Results: Through technical refinement and experience, our indications and protocol for the treatment of patients with symptomatic acetabular dysplasia with concomitant intra-articular hip pathology involves a refined and reproducible, two surgeon procedure utilizing hip arthroscopy followed by PAO. The use of intra-abdominal monitoring allows for assessment of intra-peritoneal pressures to monitor for the development of abdominal compartment syndrome secondary to fluid extravasation. Conclusion: The performance of concomitant hip arthroscopy and PAO for concurrent hip dysplasia and intra-articular hip pathology represents an increasingly common approach in hip preservation surgery. The hip arthroscopy and muscle-sparing PAO protocol using intra-abdominal monitoring described here serves to further refine and advance the indications and technical aspects of this challenging procedure.Level of Evidence: V.
