PubMed, Cochrane Central Register of Controlled Trials, and Scopus were searched using the keywords \u201chip\u201d AND \u201cmicroinstability.\u201d Studies were included that reported diagnostic criteria for hip microinstability. Exclusion criteria included review articles, technique papers, biomechanical studies, cadaveric studies, and studies focused on traumatic instability. Diagnostic criteria were categorized into 4 primary domains: physical examination findings (16 studies), intraoperative findings (17 studies), radiographic criteria (6 studies), and clinical history (1 study).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty\u2010three studies met inclusion criteria (Levels II\u2010IV).
