Patellar instability may be due to a patella with normal or pathological alignment in the femoral groove but may be dislocated by internal or external forces. Different predisposing factors to instability exist. We may consider bone factors as shape and depth of the throclea, femoral internal rotation or tibia vara; we have to consider even the soft tissues, the medial retinacula first of all, whose lesion may due to patellar dislocation. Clinical and radiological evaluation of malalignment is important to define the possible causes of the patellofemoral symptoms, generally pain and instability, that we may find in different association. Clinical evaluation is not always related to instability because not the all patello-femoral joints with predisposing factors are unstable and because not all the situations with subjective instability may be related to a situation clinically evident. In this second group of situations, a trauma may lead to the development of the disease. Clinical and strumental evaluation, in any case, is important to determine the correct strategy to patello-femoral disorders either with rehab or surgical approach.
