oblique tear of medial meniscus

If mechanical symptoms are present in this subset of patients, a partial or subtotal meniscectomy may improve symptoms; although, these tears are not usually associated with traditional meniscal-based mechanical symptoms. Nonsteroidal anti-inflammatory drugs (NSAIDs), Inability to move your knee through its full range of motion. Biologics injections, such as platelet-rich plasma (PRP), are currently being studied and may show promise in the future for the treatment of meniscus tears. The menisci are "wedge-shaped" pieces of cartilage that rest between the thigh bone ("femur") and lower leg bone ("tibia") in the knee joint. Of course, if a displaced meniscal fragment is identified, the tear is by definition unstable. Patients describe meniscal tears in a variety of ways. These tears often require surgical treatment to restore the proper function of the knee. If you've torn your meniscus, it might take 24 hours or more for pain and swelling to begin, especially if the tear is small. There is a history of sudden inability to fully extend the knee, with a rotational flexion/extension 'trick' required to regain full extension. Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, . Radial tears, because they are oriented perpendicular to the c-shaped fibers of the meniscus, have a devastating effect upon meniscal function. and oblique tear . 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. 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. Feb 1995;11(1):29-36. Complex Medial Meniscus Tear: Repair technique - YouTube Pain and/or clicking on compression suggest a meniscal lesion 1,32, Figure 3. Choose a doctor and schedule an appointment.

This tear pattern was historically unrecognized, although more recently it has been suggested this hidden pathology may account for nearly 80% of the total knee replacements in patients younger than 60 years. A flap tear is a descriptive term that refers to a situation where the meniscus tears within its midsubstance, usually in a predominantly horizontal pattern, and then the upper or lower component of the torn meniscus becomes displaced from its site of origin (14a).8 These tears are most common at the medial meniscal body, and when displaced, the flap component may migrate into the superior or inferior meniscal gutter (15a,15b). Displacement of the inner rim of the tear (arrowheads) results in the classic "bucket-handle" configuration. Grade 3 meniscus tears usually require surgery, which may include: Tips to help you get the most from a visit to your healthcare provider: Cedars-Sinai has a range of comprehensive treatment options.

Reactive synovitis and edema (arrowheads) are readily apparent deep to the tibial collateral ligament on the coronal view. Meniscus tears are extremely common knee injuries. All rights reserved. (14a) A 3D depiction of a flap tear of the posterior body of the medial meniscus illustrates displacement of the upper component of the flap (arrow) from its site of origin. Magnetic resonance imaging can also be effectively used to estimate the vascular zone classification (see Treatment) of tears.18 This is useful for the orthopaedic surgeon to predict meniscal repairability, assisting informed discussion with patients and scheduling appropriate operating theatre time.18 It is essential to remember that just because a tear can be seen on MRI, this does not mandate surgery. They may not even be apparent with an arthroscopic examination. This is termed the 'red-red zone' (denoting area of vascularity).2,4 repair of the 'red-white zone' (watershed area between vascular and avascular meniscus) is controversial25 with many different surgical techniques.26 tears in the 'white-white zone' (avascular zone) are rarely repaired rather the damaged segment is resected (meniscectomy). AAOS does not endorse any treatments, procedures, products, or physicians referenced herein. The double posterior cruciate ligament (PCL) sign appears on sagittal MRI images of the knee when a bucket-handle meniscal tear (medial meniscus in 80% of cases) flips towards the center of the joint so that it comes to lie anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller ligament.. A double posterior cruciate ligament sign from a torn medial meniscus can . Clinical: Most trauma to knee joint is caused by a lateral blow at knee level when foot is planted when knee is slightly flexed. Intrasubstance/incomplete tear (top left) This type of tear is often a sign of degenerative changes in the meniscus tissue. The procedure begins with a complete diagnostic arthroscopy using a 30-degree arthroscope. AJSM 2002; 30:589-600.

I have been diagnosed with a subtle oblique tear involving the posterior horn of the medial meniscus and extends to the inferior articular surface of the meniscus. Most commonly it is impossible to fully extend the knee; more accurately described as stiffness (termed 'pseudo locking') due either to a small effusion (requiring increased force to bend the tense joint capsule) or to pain inhibition as the femoral condyle compresses the torn meniscus. The posterior horn is located on the back half of the meniscus. The RICE protocol is effective for most sports-related injuries. 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. The menisci the medial meniscus and lateral meniscus - are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). With proper diagnosis, treatment, and rehabilitation, patients often return to their pre-injury abilities. The typical meniscal pain profile comprises well localised joint-line pain (with medial pain generally being indicative of a medial tear and vice-versa). These are paraphrased. In older patients, referral is appropriate if conservative management fails to improve symptoms. The described meniscal tears will lead to possible necessary total knee replacement. Note: the cartilage deficit more anteriorly on the medial femoral condyle and altered subchondral cortical bone interface, Figure 5. The relationships among MM radial/oblique tears, MM extrusion (MME), and the effect of arthroscopic meniscal repair are not established. Jarit G, Bosco J. Meniscal repair and reconstruction. Surgical treatment is usually reserved for younger patients with a vertical longitudinal tear within the vascularised outer third of the meniscus. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. Oblique Tear | definition of Oblique Tear by Medical dictionary Each knee has two C-shaped pieces of cartilage known as menisci. However, these patients are rare. Only a small peripheral rim of meniscal tissue (arrowhead) is present at the native site of the lateral meniscus. Verdonk PC, Demurie A, Almqvist KF, Veys EM, Verbruggen G, Verdonk R.

The views expressed by the authors of articles in Australian Family Physician are their own and not necessarily those of the publisher or the editorial staff, and must not be quoted as such. We have also seen complete meniscal root avulsions in the cruciate ligament-injured knee with complete injury of the medial ligament and posterior oblique ligament that opens in full extension. The tear should be eight millimeters or more in length, as shorter peripheral longitudinal tears are less likely to be symptomatic and may heal spontaneously. Vincken PW, ter Braak AP, van Erkel AR, et al. J Fam Pract 2001;50:93844. AJR Am J Roentgenol 1998;170:5761. Sports-related meniscus injuries often occur along with other knee injuries, such as anterior cruciate ligament (ACL) tears. Larger, unstable tears of this type often cause mechanical symptoms, however, and therefore warrant operative treatment, usually via partial meniscectomy. Sometimes conservative treatment doesnt work. RACGP - Meniscal tear - presentation, diagnosis and management A meniscal tear can heal on its own, but location is important.
