parrot beak tear

(redirected from Oblique Tear)
The most common meniscal tear, a type of radial tear which begins at the free (inner) edge like other radial tears, but then curves into a longitudinal orientation—similar to longitudinal meniscal tears—as the tear extends toward the meniscal periphery. As the tear is traced on sequential MR images, it moves closer to the outer portion of the meniscus and then remains equidistant from the outer meniscal margin on subsequent images, as seen on longitudinal tears
