Patellar Instability, Patellar Dislocation
Torsion of the Tibial Tuberosity, a New Factor of Patellar Instability?
Patellar instability (recurrent patellar dislocation) can occur at any age. It is most often seen in young subjects, especially among adolescents. It is commonly accompanied by anatomical factors.
