Patients were categorized into two groups: Group A underwent immediate cessation, while Group B was gradually weaned using a Frejka pillow. Radiological follow-up included acetabular index (AI), lateral center-edge angle (LCEA), and assessment of AVN based on the Kalamchi-MacEwen classification, up to five years of age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The two groups were demographically similar. There were no statistically significant differences in recurrence rates (Group A: 9%, Group B: 5%;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.53) or AVN incidence (Group A: 6.25%, Group B: 10%;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.55). Group B showed a non-significant trend toward higher LCEA values at five years (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.08), potentially indicating better acetabular development.
