MRI of native knee cartilage delamination injuries

OBJECTIVE. The purpose of this article is to describe the normal imaging appearance of cartilage and the pathophysiologic fndings, imaging appearance, and surgical management of cartilage delamination. CONCLUSION. Delamination injuries of knee cartilage signify surgical lesions that can lead to signifcant morbidity without treatment. These injuries may present with clinical symptoms identical to those associated with meniscal injury, and arthroscopic identifcation can be diffcult, thereby creating a role for imaging diagnosis. A low sensitivity of imaging identifcation of delamination injury of the knee is reported in the available literature, although vast improvements in MRI of cartilage have since been introduced.
