This study evaluates the radiographic and clinical outcomes of a secondary corrective procedure, the Pre-Operative computed Tomography-assisted intertrochanteric Flexion (POTOF) osteotomy, for treating these persistent deformities.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed patients who underwent a POTOF osteotomy as a secondary procedure for SCFE between 2004 and 2020. Patients with less than two years of follow-up were excluded. We evaluated changes in the modified \u03b2 angle, incidence of avascular necrosis (AVN), relative joint space (RJS), and the modified Harris Hip Score at the final follow-up.

The mean RJS was 92% (range, 42-128%). The mean modified Harris Hip Score, available for 7 of the 11 hips, was 92.4, indicating good hip function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The POTOF osteotomy may serve as a viable secondary procedure for treating residual deformities after SCFE.
