Objectives: to assess the televance of meniscal lesion due to trauma on rnagnetic resonance imaging (MRI) and arthroscopy. Methods: Prospective study, dinit::al diagnosis of protocol, 180 meniscal tears due to trauma wete diagnosed and underwent arthroscopic surgery at Thong Nhat Hospital - Ho Chi Minh city from January 2007 to January 2012 Results: The result of diagnosis of locations where meniscus tom on the MRI image is highly appropriated with arthroscopy (Kappa index K=0.8). Conformity in the diagnosis of tom meniscus hom on MRI with the internal image is from fair to good (K=0.6). However, there is a confusion in the dorsal hom of the meniscus tears diagnostic and missed cases ate 30/68, aa:ounting for 44.2 percent. Conclusions: MRI gives approptiated results about the position, however, it only ranks from fair to good level for diagnosis hom tear in the meniscal lesions due to trauma.
