Ask if your condition can be treated in other ways. If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically. Oblique tears combine features of radial and longitudinal tears in that they lie perpendicular to the free edge of the meniscus but then curve such that a portion of it lies parallel to the c-shaped fibers of the meniscus. Although C, a vertical tear, is commonly used to describe such an appearance, the better answer is D, a longitudinal tear. Meniscal tear configurations: categorization with MR imaging.

In other words, when the majority of the meniscus forms the handle, that requires tear formation near the meniscal periphery, resulting in a vascular site for operative repair. Meniscal repairs are more likely to be successful when performed near the time of injury. All rights reserved. (6a) A radial tear of the body of the lateral meniscus also appears vertical on sagittal MR images (arrow), though in the case of radial tears, the lesion is oriented perpendicular to the c-shaped fibers of the meniscus. How can I tell if I have an oblique fracture? This most often happens when the tear develops over a period of time. Evaluation of meniscal injury accounts for most requests for MR imaging of the knee at most institutions. Both of these factors increase contact forces across the joint, leading to accelerated osteoarthritis and predisposing the patient to the development of subchondral insufficiency fractures.7. Arthroscopic total meniscectomy Occasionally, a large tear of the outer meniscus can best be treated by arthroscopic total meniscectomy, a procedure in which the entire meniscus is removed. The preferred nomenclature for this tear pattern is: A gradient-echo T2*-weighted sagittal image, A. This technique allows for anatomic reduction and fixation of the meniscal root by restoring the joint contact pressure and area similar to the intact state. Sagittal peripheral meniscal images demonstrate the normal anatomical 'bow-tie configuration' (the central meniscal body with the anterior and posterior horns as well circumscribed triangles. When small, conservative therapy or simply rasping the meniscus may result in healing of these tear types. To learn more, please visit our.

Peripheral meniscal tears are located in the most vascular portion of the menisci and comprise 39-72 % [2, 3, 56, 69, 82] of all meniscal tears. As the risk of osteoarthritis is increased if meniscal structures are not optimally functional,7 it may also be appropriate to refer all young patients for opinion if symptoms do not rapidly improve.

The kneecap (patella) sits in front of the joint to provide some protection. Video chat with a U.S. board-certified doctor 24/7 in less than one minute for common issues such as: colds and coughs, stomach symptoms, bladder infections, rashes, and more. (3a) A fat-suppressed proton density-weighted axial image through the knee joint demonstrates the C-shaped menisci. 6 This often signals a tear. The degenerative aetiology and reduced vascularisation secondary to ageing also means that meniscal tears in the elderly population are less likely to be amenable to surgical management;7 only about 6% of patients over 40 years of age have operable lesions.24 To prevent re-injury of the meniscus, activity modification is important for example, ceasing sports such as soccer or netball. Meniscus surgery is a common operation to remove or repair a torn meniscus, a piece of cartilage in the knee. The doctors at the Orthopaedic Associates of Central Maryland are here to repair your knee problems, hip pain, and arthritis issues so you can get back to enjoying life. Arthroscopic repair An arthroscope is inserted into the knee to see the tear. The parrot beak shape of an oblique tear (arrow) is readily apparent on (7a) a proton density-weighted axial image of the menisci. They act as shock absorbers and stabilize the knee. Complex or degenerative tears are where two or more tear patterns exist. Several variations in meniscal tear patterns have been granted specific names that recognize the unique characteristics of the tear. Not the symmetrical shape of the lateral meniscus (red outline) and the asymmetry of the medial meniscus (blue outline), where the posterior horn (asterisk) is significantly larger than the anterior horn. In the present case, a full-thickness radial tear of the medial meniscus is visualized (Fig 1).An arthroscopic torpedo shaver (Arthrex, Naples, FL, U.S.A.) is used to debride the meniscus tear edges back to a healthy, stable rim (Fig 2).For improved access to the medial meniscus, an 18-gauge spinal . (redirected from Oblique Tear) The most common meniscal tear, a type of radial tear which begins at the free (inner) edge like other radial tears, but then curves into a longitudinal orientationsimilar to longitudinal meniscal tearsas the tear extends toward the meniscal periphery.
