Detailed history and physical examination combined with an MRI of the knee predictably diagnose a discoid meniscus. The clinical presentation varies from being asymptomatic to snapping, locking, and causing severe pain and s … Discoid meniscus on coronal proton-density weighted MRI The transverse diameter of a normal meniscus is approximately 10 to 11 mm; therefore a normal meniscus body will be visible on only 2 slices of a MR with 4-5-mm sagittal slices.

Diagnosis certain The injury was associated with a tackle in 4 patients, while the phase of play of injury was unknown in 6 patients. In the clinical manual examination, tenderness and a positive hyperextension test had a relatively high sensitivity. In imaging examination, MRI depicted a characteristic image of a partial meniscal defect in the sagittal view. Discoid meniscus Clinical presentation. Although frequently asymptomatic, discoid menisci are prone to cystic degeneration with Pathology. Discoid menisci have decreased collagen fibers and loss of normal collagen orientation, which predisposes Radiographic features. Radiographs may well A discoid meniscus was said to be present if three or more 5-mm-thick contiguous sagittal images demonstrated continuity of the meniscus between the anterior and posterior horns.

Discoid meniscus 䡧On sagittal images, a continuous bow-tie appearance on 3 or more 4 mm slices (12 mm) 䡧Up to 2 mm higher than the opposite meniscus Discoid menisci of the knee are not uncommon, and the criteria for arthrographic diagnosis and the clinical symptoms are well known.

Three theories regarding the etiology of meniscal ossicle prevail in the literature Discoid medial menisci have been reported sporadically in the literature, and their incidence is much lower than that of discoid lateral menisci. They should be treated according to the algorithm mentioned earlier, with an understanding that discoid medial menisci are more often stable than discoid lateral menisci, given their typically more robust capsular attachments. The Wrisberg-type discoid meniscus is of normal shape but has a hypermobile posterior horn due to absence of the normal fascicles, which attach it to the joint capsule and tibia [8–12]. It is the least common variant of discoid lateral meniscus and its prevalence has been reported as approximately 0.2% .
