title: Recurrent dislocation of the patella in Turner's syndrome.
abstract: We report two patients with Turner's syndrome who presented with recurrent dislocation of the patella (RDP). Both had a positive family history of patellar instability. The association of RDP with Turner's syndrome has not been reported previously. A subsequent study in 14 patients with Turner's syndrome demonstrated radiographical patellofemoral incongruency in eight patients, but no clinical manifestation of patellar instability. Although the present study suggests a possible link between Turner's syndrome and patellofemoral incongruency, it could not ascertain whether or not Turner's syndrome predisposes a patient to RDP.
