MR of articular cartilage lesions of the knee by ProQuest


Subchondral marrow edema is more likely to be associated with higher-grade lesions30 and, in the setting of acute trauma, indicates that the lesion may be full thickness. Since the grading of cartilage lesions is largely a matter of local practice preference and no one classification scheme is overwhelmingly used over all others, our practice reports the size, depth, and location of the cartilage lesion to allow the referring physicians to fit the lesion into their own grading system.

         steoarthritis is a highly preva-
         lent disease in the United States
         population, with approximately
75% of persons over age 65 having ra-
diographic evidence of degenerative
changes, and nearly two-thirds of rou-
tine knee magnetic resonance imaging
(MRI) demonstrating articular cartilage
damage.1 Therefore, careful evaluation
of the articular cartilage is an important
part of the knee MRI examination.
