Parrot beak meniscal tearstear is are a a type of obliqueradial meniscal tear with a more oblique course, which is connected in one plane and displaced in the other plane. Its appearance on axial images isgives the characteristic appearance of a curved like a crescent and is likenedV, similar to that of a parrot's beak. TheAs it is obliquely oriented in relation to the coronal and sagittal plane, it results in a marching cleft sign on sagittal images. This type of tear gap has a curved V-shapeis usually symptomatic, as the partially torn meniscal flap in unstable.
Some authors advise that the term should be reserved for arthroscopy reports, and not used in MRI reports as a meniscal tear pattern descriptor 1.
