A patient presented with anterior knee pain after minor trauma. (a) Sagittal proton density-weighted turbo spin echo sequence shows thickening and increased signal (arrow) in the proximal patellar tendon. (b) Sagittal proton density-weighted turbo spin echo fat-saturated sequence of the same patient shows increased signal (arrow) in the proximal patellar tendon and surrounding infrapatellar fat pad, representing oedema.
