1993-12-01 · Discoid menisci are a relatively rare abnormality of the knee joint. Although a discoid lateral menis- cus was first reported by Young in 1889 (1), the first true discoid medial meniscus was not reported by Cave and Staples until 1941 (2). Since 1941, only 37 discoid medial menisci have been reported. Dr. Ebraheim’s educational animated video describes Discoid meniscus.

15 MRI has been shown to be effective in the diagnosis of discoid lateral meniscus. Any of the following factors have been shown to be specific for diagnosis: 1) 14- to 15-mm minimum transverse width of the lateral Discoid menisci of the knee are not uncommon, and the criteria for arthrographic diagnosis and the clinical symptoms are well known. Although enlarged menisci have been recognized at magnetic resonance (MR) imaging, there are no criteria for the MR imaging diagnosis. The authors describe 29 discoid menisci imaged by means of MR. OBJECTIVE. A discoid lateral meniscus is a common normal variant, occurring in approximately 3-5% of the population. A subgroup of the discoid lateral meniscus known as the Wrisberg variant occurs when there is no posterior attachment of the lateral meniscus. findings.

During arthroscopy a tear may not be visualized in some symptomatic discoid menisci. Therefore, a preoperative MRI is mandatory for all discoid menisci, Discoid meniscus - Imaging pearls. Courtesy: Dr Venkatesh M, Shades of Radiology.

Morphologically, there is poor constriction of the central portion and thickening of the free end. Three cases of discoid medial menisci were diagnosed preoperatively by arthrography. Discoid mensiscus usually occurs on the lateral side of the knee; its pathogenesis is obscure. Discoid Medial Meniscus | Radiology Discoid lateral meniscus is one of the most common knee problems in clinical practice. Several radiographic findings have been reported to screen discoid lateral meniscus, but the diagnostic value of those signs varies.We introduce a new method of measurement on plain radiograph for initial screening discoid lateral meniscus and describe its efficacy and correlation to symptomatic discoid The Wrisberg variant of the discoid lateral meniscus is a rare condition with a highly suggestive clinical history. The musculoskeletal radiologist should consider this diagnosis whenever a discoid lateral meniscus is identified because making this elusive diagnosis may prove immensely useful for the orthopedic surgeon. THE DISCOID LATERAL MENISCUS (DLM) is an ana-tomic variant of the meniscus, in which the meniscus is thickened and discoid shaped, and the DLM covers a greater area of the tibial plateau than the normal meniscus.

References: Post-operative Meniscus 3 This patient also had a suture repair for meniscal tear. After a new injury, the PD-images show high signal unequivocally reaching the surface of the meniscus (seen on the original films, but not clearly seen on the compressed image on the left). On this image, it is not possible to tell if the tear has healed. 2017-05-29 · The Discoid Medial Meniscus Pitfalls and Review of the Literature. Ann Clin Case Rep. 2017; 2: 1361. Abstract.
