TAKE-HOME POINTS
Patellofemoral instability is common in the skeletally immature age group.
Many treatment options exist for patellofemoral instability; however, a medial patellofemoral ligament (MPFL) reconstruction is an option in a skeletally immature patient.
Allograft or autografts may be utilized for the MPFL reconstruction.
Three options exist to confirm location of the MPFL origin on the patella, but only one drill tunnel is recommended in pediatrics.
During identification of MPFL origin, special views in the coronal plane should be considered to avoid injury or damage to the growth plate.

ABSTRACT
Patellofemoral instability commonly occurs in the young patient, and, often, skeletal immaturity may be a risk factor for possible recurrence. Treatment considerations, including operative and nonoperative management, are based on anatomic factors. A medial patellofemoral ligament (MPFL) reconstruction is a treatment option for a skeletally immature patient with recurrent instability or for patients with a high risk of patellofemoral instability recurrence. A physeal-sparing MPFL reconstruction technique that considers the origin of the MPFL to be distal to the distal femoral physis may be employed.
