Patients were excluded if they had prior hip surgery or had acetabular pathology beyond a labral tear. Fluoroscopic images were obtained at 0 and 100\u2009pounds of axial traction force (lbf) at multiple time points: preinstrumentation, postcapsulotomy, postcapsular repair, and at follow\u2010up during contralateral hip surgery. Linear regression assessed the change in distraction distance over time between time zero repair and the follow\u2010up distraction distance, whereas logistic regression evaluated factors associated with substantial distraction increase, defined by the minimal detectable change.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Forty\u2010one patients (41 hips, mean age 25.7\u2009\u00b1\u200911.4\u2009years, 66% female) were included.
