Preoperative and postoperative radiographic parameters were assessed, such as lateral center-edge angle (LCEA), acetabular index (AI), joint space width, and medial head border-ilioischial line distance. Clinical outcomes were evaluated using the Harris Hip Score (HHS), Postel-Merle d\u2019Aubign\u00e9 (PMA) score, and range of motion (ROM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean follow-up duration was 40.75 months (12\u201390 months). Postoperatively, the mean LCEA was 36\u00b0 (range: 29\u201345\u00b0), and the mean AI was -0.5\u00b0 (range: -6 to 4\u00b0). The joint space width was 2.5 mm (range: 1\u20134 mm), and the medial head border-ilioischial line distance was 4.5 mm (range: 3\u20138 mm). The mean postoperative PMA score was 17 (range: 16\u201318), and the mean HHS was 96.5 (range: 93\u2013100). All patients achieved normal hip ROM, with no reported cases of avascular necrosis or femoral neck fractures. One patient developed class II heterotopic ossification; however, no further intervention was required.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
