Patellar Dislocations in the Pediatric Population


Patellar dislocation is a common problem in the skeletally immature patient, and has a high rate of recurrence. The workup and management of this disorder are quite complex and vary significantly with the acuity, functional demands, and comorbidities of the patient. The principles of management of patellar dislocation in the pediatric population also differ from those in the adult population, and the pediatric patient with an acute initial patellar dislocation is managed differently from a patient with multiple recurrent dislocations. Attention should be paid to the presence of trochlear dysplasia, patella alta, a lateralized tibial tuberosity, and compromise of proximal medial soft-tissue restraints on the patella, with management varying greatly according to the location of the patient's pathology. Controversy continues to exist about appropriate management of the patient with an initial acute patellar dislocation. Pediatric patients with syndromic conditions related to patellar dislocation represent a distinct group in terms of management, and have their own special set of considerations.
