Fig. 1A. 30-year-old man with injury 2 weeks before imaging. Sagittal
spin-echo proton densityweighted MR image (TR/TE, 2000/20) with fat
suppression reveals amorphous signal in posterior horn of medial meniscus
(arrow), with subjacent high signal in tibial plateau.

Fig. 2A. 23-year-old man with reported knee dislocation. Spin-echo
proton densityweighted MR image (TR/TE, 2000/20) with fat suppression
reveals meniscal contusion (black arrow) and subtle adjacent bone
contusion (white arrow).

Fig. 3A. 39-year-old woman who injured her knee skiing several days
before imaging. Patient had tibial plateau fracture and avulsed anterior
cruciate ligament. Sagittal spin-echo proton densityweighted MR image
(TR/TE, 2000/20) with fat suppression reveals abnormal signal in posterior
horn of medial meniscus with adjacent bone contusion.

Fig. 3B. 39-year-old woman who injured her knee skiing several days
before imaging. Patient had tibial plateau fracture and avulsed anterior
cruciate ligament. Arthroscopic photograph of meniscus reveals abnormal
injection and vascularity at periphery of injured meniscus (arrows).
No meniscal tear or meniscocapsular separation was identified on arthroscopy
(F = femur; m = body of meniscus).

Fig. 1B. 30-year-old man with injury 2 weeks before imaging. Follow-up
MR image (2000/20) after 67 weeks reveals interval resolution of meniscal
signal with considerable decrease in underlying bone signal.

Fig. 2B. 23-year-old man with reported knee dislocation. Follow-up MR
image (1800/20) obtained 20 weeks after initial imaging reveals resolution of
abnormal meniscal signal.
