Discoid meniscus is fairley common in children on clinical examination to come with snapping sounds of the knees.Clinical examination shows a senstivity of 88 % v/s an MRI sensitivity of only 38 % in various series. There are 3 varieties – complete, incomplete and wrisberg variant.

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

usually lateral meniscus involved; 25% bilateral; Classification 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. A discoid meniscus was said to be present if three or more 5-mm 2011-12-01 · Discoid lateral meniscus tends to manifest as hypermobility (snapping knee) as of childhood, without tear, whereas discoid medial meniscus is asymptomatic in childhood until revealed by tear. The ultrastructure of discoid menisci differs from that of normal menisci ; this difference in collagen fiber organization and the stress redistribution 2019-08-22 · Discoid lateral menisci were first described in the late 1800s. The normal configuration of a meniscus is that of a matured crescent moon, whereas that of a discoid meniscus generally is a thickened, very early crescent moon. MRI findings with arthroscopic correlation for tear of discoid lateral meniscus: comparison between children and adults.

2017-05-29 · The Discoid Medial Meniscus Pitfalls and Review of the Literature. Ann Clin Case Rep. 2017; 2: 1361. Abstract. The discoid meniscus is a rare meniscal abnormality. Through this case of a patient with internal discoid meniscus, we propose to study that malformation, clinical and radiological presentation and therapeutic modalities. If you do any sort of sports medicine, you’ve heard of the meniscus, that shock absorber between the bones in the knee.

A discoid meniscus is more prone to injury than a normal meniscus. The thick, abnormal shape of a discoid meniscus makes it more likely to get stuck in the knee or tear.

Discoid meniscus is thought to arise secondary to an abnormal inferior fascicular attachment of the posterior horn, resulting in additional central meniscal growth and subsequent discoid configuration. Morphologically, there is poor constriction of the central portion and thickening of the free end.

There are three types of discoid menisci (A) incomplete: the lateral meniscus is a bit thicker and wider than a normal meniscus (B) complete: the tibia is completely Complete and incomplete discoid menisci with no tears are typically treated with saucerization, a procedure in which the meniscus is cut and re-shaped into a Feb 23, 2017 Discoid lateral meniscus is a common abnormal meniscal variant in children. Detailed history and physical examination combined with an MRI Discoid meniscus most often affects the lateral meniscus, which is the on the outside of the knee joint. Page 2.

Diagnosing DM on MR imaging has clinical and surgical implications. When diagnosing a DM on MR imaging, identification of tears and signs of instability is of utmost importance. Discoid meniscus is fairley common in children on clinical examination to come with snapping sounds of the knees.Clinical examination shows a senstivity of 88 % v/s an MRI sensitivity of only 38 % in various series. There are 3 varieties – complete, incomplete and wrisberg variant. Discoid Lateral Meniscus; Freiberg's Disease; Evolution; Synovial Osteochondromatosis; MS presenting with severe headache; Rotator Interval Tear; CT IVP; Subdural Haemorrhage Acute on Chronic June (3) May (4) April (14) March (9) February (2) January (9) 2008 (41) RESULTS: For the prospective MR interpretations, the PPV for discoid meniscus was 92%. PPV for discoid meniscal tear was 57%. PPVs for individual types of discoid meniscal tears were 46% (peripheral tear, 19/41), 76% (peripheral tear with horizontal tears, 16/21), 56% (horizontal tear, 5/9), 50% (transverse tear, 1/2), 67% (horizontal tear combined with transverse tear, 2/3), and 100% (longitudinal tear, 1/1).

Alternatively, a discoid lateral meniscus shows more than two meniscal body segments on consecutive sagittal images of the knee. Healthy menisci are shaped like crescent moons (in fact, "meniscus" comes from the Greek word for crescent). A discoid meniscus is thicker than normal, and often oval or disc-shaped.

Patients with discoid lateral menisci have variable enlargement of the meniscal body, often with thickening of the meniscus as well. THE DISCOID LATERAL MENISCUS (DLM) is an anatomic 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. discoid meniscus is larger than usual; also referred to as "popping knee syndrome" Epidemiology . incidence .

The presence of medial discoid meniscus is extremely rare with an incidence of 0.06%-0.3%, compared to the reported rate of lateral discoid meniscus, which ranges from 1.4% to 15.5% [1, 2, 3]. Discoid lateral meniscus is a common abnormal meniscal variant in children. A detailed history and physical examination, when combined with an MRI of the knee, can predictably diagnose a discoid meniscus. The discoid meniscus was typically classified as type I (complete), type II (incomplete), or type III (Wrisberg variant).

Tears are more common with the complete discoid meniscus variant and often display horizontal or longitudinal tear patterns . MR imaging has widely variable sensitivity and specificity for detection of tears within a discoid meniscus because of the increased meniscal vascularity and diffuse intrameniscal signal intensity (34,35). Therefore

15 MRI has been shown to be effective in the diagnosis of discoid lateral meniscus. Discoid meniscus is thought to arise secondary to an abnormal inferior fascicular attachment of the posterior horn, resulting in additional central meniscal growth and subsequent discoid configuration. Morphologically, there is poor constriction of the central portion and thickening of the free end.

3D MRI should further improve the diagnosis of meniscal tears. Finally, in the presence of a discoid meniscus, X-rays can identify the relative widening of the

At first impression this looks like a tear within a discoid meniscus. At closer look you will notice that the horizontal structure has a lower signal intensity than the meniscus and looks funny. This is a normal variant caused by a vacuum phenomenon.

Jun 17, 2015 Learn in-depth information on Discoid Meniscus, its causes, symptoms, diagnosis , complications, treatment, prevention, and prognosis.

Epidemiology Discoid menisci are congenital, frequently bilateral (up to 50%) an The most prominent distinguishing features of discoid lateral meniscus on plain radiographs include widening of the lateral joint space and a high fibular head. 12,14,15 Additionally, marginal osteophytes and cupping or flattening of the lateral tibial plateau may be revealed. 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.

Discoid meniscus in children: treatment and outcome. Can J Surg. 2003; 46(5 Discoid meniscus is an abnormal meniscus that is thicker than normal and has a different shape and texture that usually affects the lateral meniscus of the knee 1).
