Meniscal tears due to injury are rather common lesions, caused by traffic, daily life accidents or sport activities. To learn the value of MRI in the diagnosis of meniscal tears due to knee injury, we cpnducted MRI scanning for 71 patients who underwent knee arthroscopy surgery at Central Military Hospital No.108, during the period from January 2008 to February 2011. The results showed the common age was the labor one (less than 50 years old), accounting for 84.5 percent; the mean age was 39.6. The rate of male/female =2.4. MRI: Horizontal and bucket-handle tears were the most common lesions, accounting for 21.5 percent each, flap tears 20.0 percent, longitudinal tears - 13.8 percent, complex tears - 12.5 percent, and radial tears - 10.7 percent. The sensitivity of MRI in the diagnosis of meniscal tears was 98.4 percent, the specificity - 71.4 percent. At present, MRI is the best non-invasive imaging method in the diagnosis of meniscal tears, contributing to limiting diagnostic arthroscopy, and to guiding and prognosing surgery.
