Abstract:
Objective To investigate the MRI signs of discoid meniscus and to establish the criterion of MRI diagnosis.Methods 40 cases of discoid meniscus were analysed retrospectively. The methods of measurement and the classification of discoid meniscus were studied. Besides, the injurious criterion of diagnosis were discussed.Results All of 40 cases were lateral discoid meniscus. 24 cases were classified as slab type and 16 cases wedge type. 38 cases developed in different degree of meniscal injury. The rate of injury was 95%. Conclusion MRI examination is principal in diagnosis of discoid meniscus. Proportion of transverse diameter of the midbody of meniscus to the transverse width of the tibia exceeded 40%, which is necessary to diagnose discoid meniscus.
