As PAO is typically concentrated in specialized centres, many patients travel considerable distances for treatment. The purpose of this study was to evaluate the influence of travel distance on short\u2010term outcomes following PAO.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This prospective registry study included 296 hips undergoing PAO for DDH between January 2022 and May 2025 by a single experienced surgeon. Travel distance was determined using driving distance, and hips were stratified into two groups: \u226480.5 and &gt;80.5\u2009km from the treating centre. Radiographic parameters, patient\u2010reported outcome measures (PROMs) and rates of achieving the Patient Acceptable Symptom State (PASS) and Minimal Clinically Important Difference (MCID) for the modified Harris Hip Score (mHHS) and international Hip Outcome Tool\u201012 (iHOT\u201012) were analysed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 126 hips (43%) resided \u226480.5\u2009km and 170 hips (57%) &gt;80.5\u2009km from the treating centre.
