Exam showed a mild effusion and medial joint line tenderness. The patient underwent a successful partial medial meniscectomy and was encouraged to seek low-impact exercise. As DLM is a congenital anomaly, the ultrastructural features and morphology differ from those of the normal meniscus, potentially leading to meniscal tears. snapping knee due to hypermobility. separate the cavity. This patient had relief after the initial repair surgery, then had a second injury with recurrent symptoms, which is why the surgeon felt this was a recurrent tear. > 20% ratio of meniscus to tibia on the coronal image; Minimum diameter 14-15 mm on a midcoronal image; 75% Choi S, Bae S, Ji S, Chang M. The MRI Findings of Meniscal Root Tear of the Medial Meniscus: Emphasis on Coronal, Sagittal and Axial Images. PDF ssslideshare.com Dr. Michael Gabor answered Diagnostic Radiology 35 years experience No,: It doesn't sound like a bucket handle tear Total meniscectomy is rarely performed unless the meniscus is so severely damaged that no salvageable meniscal tissue remains. Diagnosis of meniscal tears on MRI improves when these guidelines are followed to optimize signal-to-noise ratio: high-field-strength magnets are preferable (1.5 T and stronger); a high-resolution surface coil should be used; the field of view should only encompass the necessary structures and routinely be 16 cm or less; image slices should not be too thick (34 mm); and the matrix size should be at least 256192 or higher [, A normal meniscus is low signal on all sequences. Meniscus Tears: Understand your MRI results | Scott Hacker MD Diagnosis - clinical presentation with exclusion of advanced knee osteoarthritis. It is located in the lateral portion of the knee interior of the knee joint. Tolo VT. Congenital absence of the menisci and cruciate ligaments of the knee: A case report. Meniscal tears were found on MRI or arthroscopy in all 28 patients with a lateral cyst overlying the body or posterior horn of the lateral meniscus, whereas a tear was found on MRI or arthroscopy in only 14 (64%) of 22 patients with cysts adjacent to or extending to the lateral meniscus anterior horn (p = 0.006). Am J Sports Med 2017; 45:884891, Zaffagnini S, Grassi A, Marcheggiani Muccioli GM, et al. Figure 7: Meniscofemoral ligament. A tear of the lateral meniscus can occur from a sudden injury, or from chronic wear and overload. Studies on meniscus root tears have investigated the relationship of osteoarthritis and an anterior cruciate ligament tear. 1. Atypically thick and high location No paralabral cyst. Methods Eighteen patients who had arthroscopically confirmed partial MMPRTs were included. Radiology. Complex or deep radial tears were found in three of five cases of lateral meniscus extrusion and normal root. Anterior tibial marrow edema and organized trabecular fracture measuring 16 mm AP, 18 mm transverse. Radial Meniscal Tear - ProScan Education - MRI Online normal knee. the rare ring-shaped meniscus, to the classification. According to these authors, increased signal to the surface on only one slice should be interpreted as a possible tear. Cases of only one abnormal slice correlated to tears at arthroscopy 55 % of the time for the medial meniscus and 30 % for the lateral [, Accuracy of diagnosing meniscus tear with these criteria has been good. Diagnosis of recurrent meniscal tears: prospective evaluation of conventional MR imaging, indirect MR arthrography, and direct MR arthrography.
