Figure 1. The fat pad adjacent to the kneecap (Hoffa's fat pad, infrapatellar fat pad) can change in signal on MRI when the knee is inflamed. (A) Normal knee without signs of inflammation. (B) Arrow pointing on a circumscribed area with higher signal (bright lines) in the area of the fat pad (normally dark), which is indicative of a beginning inflammatory reaction. (C) The whole fat pad has a higher signal (light grey color with white lines), which is a sign of progressive inflammation of the knee joint.
