a–f Comparison of the patellofemoral indices with the realignment brace (gray lines) and without the brace (black lines) at full extension (0° flexion) and 15° and 30° flexion with upright weight-bearing condition. Data presented as mean ± SD. Asterisks indicate significant group differences based on post hoc pairwise comparisons (p ≤ 0.05); according to Bonferroni correction (0.05 / 36), a p < 0.0014 was considered as significant
