Objective: We aimed to investigate the effect of the presence of discoid meniscus (DM) on the anatomical structures of the knee joint. Methods: The knee magnetic resonance (MR) images of 144 (97 female, 47 male) individuals with DM and 159 (94 female, 65 male) individuals with normal meniscus were evaluated. Results: DM was mostly seen on the left side (n=64). This was followed in decreasing order by the right side and bilateral. The incidence of DM was higher in individuals aged 36 years and older than in 18 years and younger (p=0.003). Incomplete type DM was seen most frequently in both genders. Meniscopathy was most common (n=21) in the medial meniscus of people with DM. Unilateral lateral meniscopathy was more common in individuals with bilateral DM. And also in individuals with normal meniscus, meniscopathy was also most common (n=31) medially. Unilateral medial meniscopathy was the most common in those with normal meniscus. When the affected ligaments were examined, tearing and degeneration were most common (n=21) in the ligamentum cruciatum anterius (LCA) in individuals with DM. On the other hand in the presence of DM, chondropathy (n=42) on adjacent joint surfaces was reported. It was determined that ligament damage was mostly (n=43) in LCA in normal menisci. In addition, the presence of chondropathy was observed on the bone surfaces adjacent to the joint (n=64) in normal menisci. Conclusion: Almost all of the DM was located in the lateral meniscus. This was mostly accompanied by meniscopathy and LCA injury. [ABSTRACT FROM AUTHOR]
