A 48-year-old female who presented with severe knee pain. (a) Sagittal proton density-weighted image and (b) coronal proton density-weighted image of the left knee revealed a tibial eminence avulsion fracture (black arrows) with preservation of the integrity of the ACL fibers (white arrows). (c) An axial T2-weighted image with fat suppression reveals the footprint of the avulsion fracture (hollow arrow) on the anterior tibial plateau. (d) Sagittal proton density-weighted image with fat-suppression reveals a medial meniscus tear (grey arrow).
