Abstract:
Objective The special features of discoid meniscus(DM) symptoms， the relationship between the symptoms and the signs of DM, the type and scale of DM injury as well as the prognosis were studied. Methods According to the analysis of 64 cases of DM diagnosed by arthroscopy, a comparitive analysis was made and the following topics were addressed: the distribution of the complete type of DM in patients of different age groups, the signs of locking and non-locking, with or without effusion, snapping and non-snapping, a comparison of the distribution of the snapping in different groups of injury types, a comparison of the distribution of the flexion contracture in different types of injury, a comparison of the distribution of the rates of the total and subtotal menisectomy in different groups divided according to the period of pain, the presence of effusion, the presence of locking, snapping, quadriceps atrophy and extension function. The data was analysed statistically. Results There is significant difference in the distribution of the complete type DM between 20 and over 20-years of age(P0.05). Conclusion The complete type of DM was mostly seen in cases below 20 years of age and was rarely seen in cases with the locking sign. Snapping sign was mostly seen in cases of complicated and extensive injuries and was one of the indications of arthroscopic surgery. Knee flexion contracture was mostly seen in cases of longitudinal and extensive injuries. The estimation of the results of arthroscopic surgery for DM is difficult on the bases of the clinical symptoms and signs.
