Congenital dislocation of the patella may present as an isolated anomaly or may be associated with other lower limb deformities as part of a more complex malformative or dystrophic syndrome. One type is the congenitally dislocated patella fixed irreducibly from birth in a lateral position, and second is the obligatory patella dislocation that is hypoplastic to start with and gradually gets fixed into the lateral position as the child grows. We report the surgical management of a 16-year-old boy with neglected obligatory dislocation of bilateral patellae with 2-year follow-up results.
