Should Acetabular Retroversion Be Treated Arthroscopically? A Systematic Review of Open Versus Arthroscopic Techniques


Purpose: To compare patient-reported outcomes, progression of radiographic arthritis, revision rates, and complications for hips with acetabular retroversion treated by open versus arthroscopic methods.

Methods: The PubMed and EMBASE databases were searched in August 2016 for literature on the open and arthroscopic techniques using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) method. All studies published in the English language that focused on the surgical treatment of femoroacetabular impingement caused by retroversion were included. All arthroscopic procedures, such as acetabuloplasty and labral repair, and open procedures, including anteverting periacetabular osteotomy and surgical dislocation with osteoplasty, were included. Articles that did not describe how retroversion was defined were excluded, as were studies with less than 6 months' follow-up and fewer than 5 patients. Two authors screened the results and selected articles for this review based on the inclusion and exclusion criteria. All results were scored using the Methodological Index for Non-randomized Studies (MINORS) criteria.

Results: There were 386 results returned and 15 articles that met the inclusion criteria of this study. Among the studies, 11 reviewed arthroscopic techniques and 4 reviewed open surgical procedures. Both techniques yield good results based on patient-reported outcomes with minimal progression of osteoarthritis and low complication rates.

Conclusions: This review showed statistically and clinically significant improvements for the treatment of acetabular retroversion based on patient-reported outcomes, with low progression of radiographic arthritis, revision rates, and complications using both open and arthroscopic methods.
