Purpose: To compare patient populations and outcomes in studies treating borderline hip dysplasia (BHD) with either hip arthroscopy or periacetabular osteotomy (PAO).
Methods: We conducted a literature review according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify studies published after 2014 that reported patient-reported outcome measures (PROMs) after hip arthroscopy or PAO for BHD. Preoperative demographic characteristics, radiographic variables, operative findings, procedures, postoperative outcomes, and complications were recorded.
