What is the reason of the high fibular head in the Discoid Lateral Meniscus?

초록

The purpose of this study was to assess the factors associated with high fibular head in symptomatic discoid lateral meniscus (DLM). Eighty-seven patients with complete DLM (discoid group) and 80 normal subjects (control group) were included prospectively. Plain X-rays and MRI were analyzed for level and angle of the fibular head and thickness and type of Wrisberg ligament. Multivariate regression analysis was performed to find the factors associated with levels of the fibular head and DLM. The angle of the fibular head was the only factor associated with level of the fibula in the discoid group (odds ratio : 3.0, p=0.007). The 13.6mm cut off value for fibular level had 70.5% sensitivity and 77.0% specificity for diagnosis of DLM. A high fibular head was associated with larger angle and type of fibular head.
