(8a) The curvilinear course of oblique tears often results in abnormal vertical signal (arrows) that progresses towards or away from the free edge of the meniscus on consecutive images, as seen in these sequential images of an oblique tear (arrows) of the posterior horn of the medial meniscus. Nonsurgical treatment is an option for elderly patients, those with significant comorbidities and those with advanced OA (Outerbridge grade 3 or 4 chondromalacia of the ipsilateral compartment).

By the time people reach their twenties or thirties, intrasubstance changes of the meniscus tissue are common. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. what is the treatment? In brief: meniscal tears. Meniscal injury and repair: clinical status. With advances in surgical techniques and instrumentation, meniscal root repair is a viable option that can restore the biomechanics and kinematics of the knee (Figure 4). A tear can also develop slowly as the meniscus loses resiliency. Case Discussion Longitudinal tears, also known as vertical tears, occur perpendicular to the tibial plateau and parallel to the long axis of the meniscus splitting the meniscus into inner and outer parts. The oblique meniscomeniscal ligament is but one of several known structures that can mimic meniscal pathology. How to treat oblique tear of medial meniscus? Posterior Horn Medial Meniscus Tear | Knee Meniscus Tear Recovery and rehabilitation take a few weeks.

Several variations in meniscal tear patterns have been granted specific names that recognize the unique characteristics of the tear. A case also can be made for medial meniscal root repairs for a symptomatic acute and possibly a chronic medial meniscal root tear in a non-obese patient older than 40 years with a MRI that does not have early arthritic changes. This makes the medial meniscus less mobile and is one reason why the medial meniscus is more prone to injury.3 In adults, only the periphery of the meniscus remains vascularized. 2023 Cedars-Sinai. Disclosures: Blake and Johnson report no relevant financial disclosures. Krych AJ, McIntosh AL, Voll AE, Stuart MJ, Dahm DL.

Medial meniscal posterior root tears represent an often unrecognized pathology with potentially devastating long-term effects. Physical therapy should start immediately after surgery and include early passive range of motion from 0 to 90 for the initial 2 weeks and progress to full range of motion thereafter. What is the posterior horn of the medial meniscus? Because of their importance and the clinical impact of meniscal tears, assessment of the menisci has become the most common indication for MR of the knee. These are often 'bucket-handle tears', in which there is a vertical or oblique tear in the posterior horn running toward the anterior horn,5 forming a loose section which remains attached anteriorly and posteriorly.1 In older patients, tears are generally due to degeneration associated with ageing and tend to be horizontal tears. 2010. a feeling that your knee is catching or locking, usually when it's bent - you may notice it clicking.

Athletes, particularly those who play contact sports, are at risk for meniscus tears. Damaged avascular meniscus must be removed.27 However, meniscectomy causes long term osteoarthritis,28 so is only performed when the patient suffers joint locking or mensical pain that is refractory to conservative management. 1) [50], [51], [52].Its reported prevalence in middle-aged (45-55 years) individuals .

London;1897. This means that athletes, especially those who participate in contact sports like football, are at a higher risk of sustaining this injury. Although a successful outcome of a meniscal root repair is predicated upon appropriate indications for the repair, not all medial meniscal root tears should be repaired. Those with a meniscus tear are also more likely to develop osteoarthritis in the injured knee. This "C" shaped cartilage helps disperse impact and displace force exerted upon the knee while walking, running, and other mild to high-energy and impact motions. Because other knee injuries can cause similar symptoms, your doctor may order imaging tests to help confirm the diagnosis. Survivorship analysis and clinical outcome of one hundred cases. 11 Plain radiography is only useful to exclude differentials and computed tomography (CT) is markedly inferior to MRI for meniscal imaging.12 Magnetic resonance imaging is the gold standard, first choice for investigation of suspected meniscal tears.2,1316. When small, conservative therapy or simply rasping the meniscus may result in healing of these tear types. This information is not intended as a substitute for professional medical care.

A meniscal tear can heal on its own, but location is important. The menisci are "wedge-shaped" pieces of cartilage that rest between the thigh bone ("femur") and lower leg bone ("tibia") in the knee joint. 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 .

The menisci the medial meniscus and lateral meniscus - are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). Displaced meniscal tears are by definition unstable, and should be repaired relatively quickly, as displaced meniscal fragments may fibrose and distort, making delayed repair difficult or impossible.
