@entity4713 ( @entity6995 ) dissecans ( @entity3119 ) is a common condition in @entity1 , adolescents, and young adults. Describing @entity174 and epiphyseal ossification disturbances and considering these three conditions as one entity has caused much @entity911 . Age distribution and localization combined with the radiologic and surgical presentation distinguishes these conditions. @entity1843 represents an @entity75 with secondary involvement of the overlying cartilage. Beginning as @entity2530 , @entity3119 forms a transitional zone that harbors the potential of restoration with complete healing or progression to an @entity154 . Mechanical and traumatic factors are etiologically dominant in @entity3119 , but a predisposition seems to be a contributing factor in some @entity1 . @entity1843 is generally diagnosed by conventional radiology. Its therapy is determined by the stage of the lesion and MRI will become the method of choice for staging. Intact cartilage, contrast enhancement of the lesion, and absent "cystic" defects are findings of MRI stage I and justify conservative therapy, obviating arthroscopy. Cartilage defect with or without incomplete separation of the fragment, fluid around an undetached fragment, and a dislodged fragment are MRI findings observed in stage II and require arthroscopy with possible intervention. Thus, MRI can noninvasively separate non-surgical from possibly surgical lesions and should replace diagnostic arthroscopy.
