[Evaluation of MRI of knee by arthroscopy].

Between August 1989 and April 1993, 61 patients (68 knees) suspected of having intraarticular knee pathology underwent magnetic resonance imaging (MRI) before arthroscopy. In order to evaluate the diagnostic value of the MRI of knee joints, a retrospective study was undertaken. The analysis of the correlation between the arthroscopic findings and the results of MRI indicated the high sensitivity and specificity of MRI in diagnosing disorders of the knee joint. Also the characteristics of MRI of knee and the affecting factors have been discussed in this paper.
