TREATMENT OF PATELLOFEMORAL INSTABILITY IN CHILDHOOD WITH CREATION OFA FEMORAL SULCUS

Four patients with six knees with patellofemoral instability and sever e trochlear dysplasia were treated with creation of a femoral sulcus. None of the six knees have had recurrent dislocations at 3- to 11-year follow-up. All patients had chromosomal abnormalities and limited mot or demands. We recommend this procedure for children with patellar ins tability refractory to standard treatment methods who have severe troc hlear dysplasia and limited motor demands.
