Corrigendum to “Comparison of baseline outcomes between surgical and nonoperative management in youth with lower extremity torsional abnormalities” [J Orthop 73 (2026) 227–233]

Lower extremity torsional abnormalities (LETA) include excessive femoral and/or tibial torsion and can be associated with pain, functional limitations and patellofemoral instability. This study examined whether clinical differences exist between surgically and nonoperatively managed patients. Patients aged 10-21 years with LETA referred for nonoperative or surgical treatment underwent imaging, physical assessment (range of motion (ROM), handheld dynamometry, patellofemoral tests), gait analysis and patient-reported outcomes (PROs: PODCI, FAQ, PEDI-IKDC, APPT, Cosmetic ratings, PROMIS, HAGOS). A control group of typically developing participants underwent the same assessments except imaging. Groups were compared using ANOVA/Kruskal-Wallis test, and statistical parametric mapping. Thirty-four patients (surgery n=21, 16.3 ± 2.3 years; nonoperative n=13, 14.7 ± 2.0 years) and 21 controls (15.8 ± 2.7 years) were included. Femoral version, tibial torsion, ROM, and muscle strength did not differ between treatment groups. Signs of patellofemoral instability were more frequent in the surgical group (MPFL laxity: 14/21 vs 1/13, p
