**3. Conclusion**

Discoid meniscus, despite numerous studies, remains a great unknown. There is no conclusive evidence on the cause of discoid shape, or what causes its further design. The differences that exist with respect to normal histological meniscus are largely documented. The lack of histological study of the ultrastructure is reflected in the fact that the samples obtained during arthroscopic surgery were parts of symptomatic discoid meniscus. An undamaged and complete discoid meniscus that is asymptomatic is almost impossible to examine histologically, as this would lead to deterioration of the knee joint. Nevertheless, the first studies give us a guideline for further work.
