ABSTRACT
Background and Aim: Meniscal flounceis a rare, wavy shaped folding along the free edge of the meniscus that observed in .MRI images. This is a feature of transient distortion of a normal meniscus but it can be regarded as a pseudo- meniscal tear. The aim of the current study was to evaluate the incidence of this normal variant
Materials and Methods: A total number of1001 knee MRI images were prospectively studied to check meniscal flounce and meniscoligamentous injuries in patients referred to. Kosar MRI center of Imam Reza hospital in Mashhad [2009-2011]
Results: In this study the most common meniscoligamentousinjury was diagnosed in the right medial meniscus [17.8%]. The most common accompanying injuries were the right medial meniscal tear and the right anterior cruciate ligament. The incidence of meniscal fluencewas 1%
Conclusion: The meniscal flounce observed in MRI images should be carefully interpreted because it can simulatea meniscal tear. This underscores the importance of correlating diagnostic images with clinical signs and symptoms and also avoidance of unnecessary MRI requisition inpatients whom some low probable diagnostic doubt exists
