Description	An anatomic anomaly of the knee with characteristic of abnormal geometry of the femoral part of the patello-femoral joint. It is one of the main factors causing patellar dislocation. Present in 96% of patients with symptomatic patellar dislocation. It is observed in all ages, but is more frequent during childhood and adolescence. The femoral trochlea loses its normal concave anatomy to become flat and sometimes convex with highly asymmetrical facets. This causes a patellar tilt which could lead to patellar dislocation during knee flexion.
