MRI shows edema in the inferolateral aspect of the patellofemoral joint in the majority of patients. Cystic changes may also be seen adjacent to the lateral femoral condyle. In a minority of patients, these cystic changes may be all that is seen. Some patients will also demonstrate patella alta or lateral subluxation of the extensor mechanism.

Patellar Tendon–Lateral Femoral Condyle Friction Syndrome
Patellar tendon–lateral femoral condyle friction syndrome, also known as supero-lateral fat-pad impingement syndrome, is a common cause of chronic anterolateral knee pain. Patients present with knee pain exacerbated by hyperextension and focal tenderness at the lateral side of the inferior pole of the patella. Conservative treatment consisting of taping of the superior pole of the patella is often used.
