Fig. 2A. —Arthroscopically proven horizontal tear in 53-year-old man.
Sagittal (A) and coronal (B) proton density—weighted MR
images (TR/TE, 3600/20) show tear (arrow) separating meniscus into
upper and lower parts.

Fig. 3A. —Arthroscopically proven longitudinal tear in 20-year-old man.
Consecutive sagittal proton density—weighted MR images (TR/TE, 3500/16)
show that meniscal tear (arrow) remains equidistant from outer
meniscal edge on serial images.

Fig. 4A. —Arthroscopically proven radial tear in 54-year-old woman.
Consecutive fat-suppressed sagittal proton density—weighted MR images
(TR/TE, 3200/17) show that no meniscus (arrows, A) is seen
through radial tear on A, but nontorn portion of meniscus is seen on
adjacent image (B).
