    Trochlear dysplasia is a significant factor in habitual patellar dislocation among children.

  • 2

    This study analyzed postoperative trochlear morphology in 19 children under 10 years with habitual patellar dislocation.

  • 3

    Postoperative results showed significant improvements in femoral sulcus angle, relative trochlear depth, lateral trochlear inclination, and trochlear facet angle.

  • 4

    Preoperative age and sulcus angle were positively correlated with postoperative trochlear dysplasia outcomes.

  • 5

    Younger preoperative age (<73.5 months) was identified as an independent risk factor for better trochlear remodeling outcomes.
