Patellofemoral complications can be diagnosed by a detailed history and physical examination in most of the cases. Following the clinical evaluation, anteroposterior, lateral and patellar-axial X-rays should be ordered initially. Radiographs are usually negative in patients with isolated patellofemoral pain. An osseous lesion which is responsible for pain may be seen in a few number of cases. Lateral and axial radiographs particularly show important findings for patella alta, trochlear dysplasia, patellar lateralization and tilt which play an important role in patellofemoral instability. Axial computed tomographic sections allow more clear images for measurements. In addition, lateralization of the tibial tubercle can be measured.
