There are three fat pads around the knee that can become impinged and can be symptomatic.
Which Three Fat Pads?: They are the Suprapatellar, the Quadriceps and Hoffa’s fat pads.

Normal fat pads are High Signal on PD and will be dark on PDFS as they will completely fat saturate.
When they are impinged, on MRI we look for high PDFS signal in these regions.
