  		Fig. 3A. —44-year-old man with knee pain and surgically proven radial meniscal tear. Coronal T2-weighted MR image (TR/TE, 3,050/105) shows linear area of abnormal increased signal in body of meniscus consistent with radial tear (arrow).

  		Fig. 4A. —39-year-old woman with knee pain and surgically proven bucket-handle meniscal tear. Coronal turbo spin-echo T1-weighted MR image (TR/TE, 749/10) shows findings consistent with bucket-handle tear (arrow). In original MRI report, this was described as displaced meniscal flap tear, but at arthroscopy it was described as displaced meniscal bucket-handle tear.
