Children classified per Herring’s Lateral Pillar Catterall classification. They treated open-wedge osteotomy, clinical, radiological, functional parameters assessed postoperatively. The postoperative grading done using Results this study, significant improvement mean Harris Hip Score (82.96 ± 4.3 vs. 85.36 3.75; p = 0.000) observed. addition, muscle mass reduced postoperatively compared preoperative (2.64 3.82 8.52 3.73 mm; 0.000). Based on classification, 56% showed good outcomes, 36% fair outcomes. Regarding complications, 20% had infections. Conclusions our improved
