BHD was defined as lateral center edge angle (LCEA) of 20 to 25\u00b0. Subjects with BHD were matched 1:2 to controls without BHD on age, sex, body mass index, and preoperative modified Harris Hip Score (mHHS). Alpha angle, LCEA, T\u00f6nnis angle, and acetabular retroversion signs were measured on preoperative and\/or postoperative hip radiographs. Patient\u2010reported outcomes were assessed using the mHHS and the Non\u2010Arthritic Hip Score. Hip survivorship, outcome scores, and achievement of the minimum clinically important difference were compared between groups using the Mann\u2013Whitney\n                      <jats:italic>U<\/jats:italic>\n                      test or Fisher exact test, as appropriate.\n                      <jats:italic>P<\/jats:italic>\n                      values &lt;.05 were considered significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Thirty\u2010one BHD subjects (mean age 36.8 years, 71.0% female) and 62\u00a0controls (mean age 38.0 years, 71.0% female) were included.
