The aim of the study is to compare, in patients with patellofemoral joint disorders, the values related to the bone indexes of this joint, obtained from CT performed both in orthostatism and clinostatism.~Young patients with patellofemoral joint pathology, for which a diagnostic examination is necessary in order to determine a possible surgical indication, will be included in this pilot study, and will be evaluated using the Cone Beam Computed Tomography (CBCT), a machine that use a low dose of radiation compared to traditional CT systems, and allows the examination in supine and standing position knee . In this way, for the same patient it will be possible to calculate the bone indexes both in weight-bearing condition and in non-weight-bearing, comparing the values between them, to identify possible differences due to the influence of orthostatism.
