Background
Patellofemoral pain syndrome (PFPS) is a frequent disease,
especially in young patients.
The cause of this syndrome has been linked to an abnormal lateral tracking of the patella and instability factors such as patellar trochlear dysplasia or patella Alta,
leading to joint incongruence and overload that causes cartilage deterioration and femoropatellar osteoarthritis. Therefore,
early diagnosis is essential,
though it remains difficult as it is based primarily on the clinical presentation and the exclusion of other pathologies.
The radiological techniques used for the diagnosis of this pathology include conventional radiographs,
computed tomography (CT) and magnetic resonance imaging (MRI),
but these methods,
cannot provide a dynamic assessment of the joint in full range of knee flexion.
Ultrasound has been proposed as an alternative that is non-invasive,
accessible and with no ionizing radiation.
Other radiologic examinations have prescribed protocols for image acquisition,
but in ultrasound,
as it is dynamic,
the image acquisition is complex and operator dependent.
The aim is to perform a standardized procedure of ultrasound examination in patients with PFPS,
identify the cause of it,
and then evaluate the patients with other methods,
such as CT or MRI.
