“…On MRI, a discoid meniscus can be diagnosed when the ratio of the minimal meniscal width to the maximal tibial width is more than 20% on the coronal image, and the ratio of sum of the width of both lateral horns to the maximal meniscal diameter on the sagittal image is more than 75%42). Araki et al43) have proposed that the discoid meniscus is present when the meniscal width is over 15 mm on the coronal slice.…”

There is a greater incidence of discoid meniscus in Asian countries than in Western countries, and bilateral discoid menisci are also common. The discoid meniscus may be a congenital anomaly, and genetics or family history may play a role in the development of discoid menisci. Because the histology of discoid meniscus is different from that of normal meniscus, it is prone to tearing. Individuals with a discoid meniscus can be asymptomatic or symptomatic. Asymptomatic discoid menisci do not require treatment. However, operative treatment is necessary if there are symptoms. Total meniscectomy leads to an increased risk of osteoarthritis. Therefore, total meniscectomy is generally reserved for rare unsalvageable cases. Partial meniscectomy (saucerization) with preservation of a stable peripheral rim combined with or without peripheral repair is effective, and good short-, mid-, and long-term clinical results have been reported.

“…Grade 1 and grade 2 lesions indicate mucinous or mucoid intrasubstance degenerative change and are usually encountered after 3 or 4 decade. Due to prominent vascularity in children and young adults misinterpretation as grade 1 or 2 tear is usual [4] [11] . Classification of tears: 1.…”

“…This ratio provided a sensitivity and specificity of 95% and 97%, respectively, even when torn menisci were present. (10,17) Discoid lateral meniscus is a common incidental finding during arthroscopy of the knee. In 1957, Kaplan recommended the total meniscectomy of the discoid meniscus (31).…”
