Patellar dislocation in Kabuki syndrome.

We describe four individuals (two females and two males) with Kabuki syndrome and recurrent dislocation of the patellaⁱ. The age of diagnosis of patellar dislocation ranged from 11 to 23 years. One individual underwent excision of the free fragment and transfer of the tibial tuberosity with good outcome. Two required patellar brace for instability. Characteristics of individuals with the syndrome at a high risk of patellar dislocation include female, adolescence or young adulthood, joint laxity, and obesity.
