Knee pain MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is abnormal signal intensity within the articular cartilage of the patella centrally indicating near full-thickness to full-thickness degeneration with at least a partial-thickness fluid-filled defect measuring approximately 1 cm in diameter. The articular cartilage of the femoral trochlea is preserved. The articular cartilage of the lateral and medial compartments is also preserved. Small cysts are noted within the tibial plateau near the attachment of the PCL which are not necessarily of any clinical significance.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: There is a mild amount of edema within the superolateral corner of Hoffa's fat pad which can be seen in patients with patellofemoral instability. The Insall Salvati ratio and TT to TG distance are both within normal limits. Subjectively, the femoral trochlea appears slightly shallow which may reflect mild dysplasia but this is equivocal.ADDITIONAL
