Radiology. The examiner can test the entire posterior horn up to the middle segment of the meniscus using the IR of the tibia followed by an extension. pivoting). Magnetic resonance imaging (MRI) is the most accurate imaging technique in the diagnosis of meniscal lesions and represents a standard tool in knee evaluation. The example above illustrates marked degenerative changes caused by loss of meniscal function. St. Louis County's newspaper of politics and culture Anterior horn lateral meniscus tear A female asked: Mri: "macerated anterior horn lateral meniscus with inferiorly surfacing tear. Heron, D, Bonnard C, Moraine C,Toutain A. Agenesis of cruciate The MRI sign of a radial tear is a linear, vertical cleft of abnormal high signal at the free edge (Fig. Arthroscopy is considered gold standard in the diagnosis of knee ligament injuries, with diagnostic accuracy up to 94% [1], [2]; and can be used therapeutically as well. Increased intrameniscal signal is commonly seen in the transplanted allograft but does not correlate with clinical outcome. Discoid lateral meniscus in children. high fibula head and a widened lateral joint space.20 Several Imaging characteristics of the Fellowship-trained musculoskeletal radiologists read 99% of the MRIs. The most common {"url":"/signup-modal-props.json?lang=us"}, Weerakkody Y, Baba Y, Knipe H, et al. The ideal technique for imaging the postoperative meniscus is a matter of active controversy and depends on the operation performed, surgeon preference and clinical question (concern for recurrent meniscal tear versus articular cartilage). One important reason for such discrepancies is a failure to understand the transverse geniculate ligament of the knee (TGL). Radiology. The same imaging criteria (as for the case of greater than 25% partial meniscectomy), the presence of fluid signal on T2-weighted or contrast extending into the meniscal substance is used to diagnose a recurrent tear. asymptomatic, although there is a greater propensity for discoid menisci The most widely used diagnostic modalities to assess the ligament injuries are arthroscopy and Magnetic Resonance Imaging (MRI). tear. Damaged meniscal tissue is removed with arthroscopic instruments including scissors, baskets and mechanical shavers until a solid tissue rim is reached with the meniscal remnant contoured, preserving of as much meniscal tissue as possible. Lateral meniscal variant with absence of the posterior coronary ligament. A tear of the lateral meniscus can occur from a sudden injury, or from chronic wear and overload. The self-reported complication rate for partial meniscectomy is 2.8% and meniscus repair is 7.6%. Interested in Group Sales? Indications for meniscal repair typically include posttraumatic peripheral (red zone) longitudinal tears located near the joint capsule, ideally in younger patients (less than 40).
