oblique tear of medial meniscus
Have swelling, stiffness or tightness in your knee. Meniscal pain occurs during torsional, weight bearing knee movements (classically pivoting on the knee while walking) as a sharp stab lasting several seconds, often followed by a dull ache for several hours. 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. Horizontal tears can be sewn together rather than removing the damaged portion. It seems that in the above knee, the biology of the medial compartment has gone off the ski slope in a degenerative fashion and reversing that ski slope fall seems to be unproven at this time, particularly in the patient with low functional demands, who is older than 40 years and who has a BMI greater than 30. Posterior medial meniscal root tears are often times degenerative, but these can also occur with multi-ligament knee injuries in the acute setting. Singapore: World scientific, 2010. An MMPH repair in an ACL-deficient knee showed a significant decrease in anterior-posterior tibial translation at all flexion angles except 60 compared with the ACL-deficient/MMPH tear state . No meniscal tears were observed. If you have a follow-up appointment, write down the date, time, and purpose for that visit. Most oblique meniscus tears are happen in the posterior third of the medial meniscus. Meniscal tears within the body of the meniscus or at the meniscocapsular junction represent a well-understood and manageable condition encountered in clinical practice. (9a) This irregular tibial surface tear (arrow) clearly lies within the peripheral, red zone, of the meniscus. Meniscal injury is common, and the medial meniscus is more frequently injured. Two wedge-shaped pieces of fibrocartilage act as shock absorbers between your femur and tibia. what is the best possible treatment? Many meniscus tears will not need immediate surgery. 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. Magnetic resonance imaging (MRI) scans. All Rights Reserved. Your doctor will generally ask you how the injury occurred, how your knee has been feeling since the injury and whether you have had other knee injuries. RICE stands for Rest, Ice, Compression, and Elevation. for a 22 year old severe pain. J Bone J Surg Am 2006;88:6607. Figure 1. Primary repair of medial meniscal avulsions: 2 case studies. However, these patients are rare. Meniscal tears are common sports-related injuries in young athletes and can also present as a degenerative condition in older patients. Because a torn meniscus is made of cartilage, it won't show up on X-rays. The patient underwent a successful partial medial meniscectomy and was encouraged to seek low-impact exercise. Arthroscopy. It is possible that your symptoms of pain, etc will improve with time without surgery.But that doesn't mean the tear healed. However, coronal sections may reveal the presence of meniscal extrusion or vertical defects, and sagittal sections may reveal the ghost sign (absence of an identifiable meniscus or increased signal replacing the normal hypointense signal of meniscal tissue). When displacement is not evident on MR images, additional criteria that suggest tear instability include the presence of fluid signal intensity within the tear on T2-weighted images, a tear that is greater than 10mm in length, and tears with complex patterns (10a). Clin J Sport Med 2009;19:912. Optimal diagnosis and management is essential to prevent long term sequelae. Knee pain: Depending on your duration of symptoms you can at least start off with physical therapy, a knee sleeve, and if there is arthritis present consider a c Read More oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. In contrast, the inner two-thirds of the meniscus lacks a significant blood supply. Additionally, the individual will not be able to move the joint due to pain. Meniscal tears may be categorized into five common configurations, including horizontal, longitudinal, radial, oblique (parrot-beak), and complex. I could not really walk on it. 13 Newman AP, Daniels AU, Burks RT. Meniscal intra-substance signal abnormalities are defined as an increased signal that does not fulfill the criteria for a meniscal tear according the "two-slice-touch" rule (i.e., it does not reach the meniscal surface on two consecutive views) and is a common finding on routine MRI of the knee (Fig. what is the treatment for that? 1 Sutton JB. Displacement of the inner rim of the tear (arrowheads) results in the classic "bucket-handle" configuration. Those with a meniscus tear are also more likely to develop osteoarthritis in the injured knee. Arthroscopic repair of meniscal tears extending into the avascular zone in patients younger than twenty years of age. Fax Your doctor will hold your heel while you lie on your back and, with your leg bent, straighten your leg with his or her other hand on the outside of your knee as he or she rotates your foot inward. Read before you think. The menisci are two rubbery disks that help cushion the knee joint. There are two in each knee, for a total of four. Available at www.health.gov.au/internet/ main/publishing.nsf/Content/MBRT-DI-submissions-018/$FILE/018%20 RACGP%20Submission.pdf [Accessed 15 August 2011]. Meniscus Repair. This provides a clear view of the inside of the knee. Radiology 2000; 217:193-200. Identification of a meniscal root tear on MRI may be challenging due to the relatively small size of the root. Meniscal repair is a more difficult surgical technique and requires a motivated, diligent patient in order to be successful. Although surgical repair has led to improved patient-reported function, there are conflicting reports on the progression of cartilage degeneration. Br Med Bull 2011;2011:89106. Rosemont, Ill. American Academy of Orthopaedic Surgeons. American Board of Orthopaedic Surgery Practice of the Orthopaedic Surgeon: Part-II, certification examination case mix. swelling . (3a) A fat-suppressed proton density-weighted axial image through the knee joint demonstrates the C-shaped menisci. A meniscus tear can occur when the knee is suddenly twisted while the foot is planted on the ground. The posterior horn is the thickest and most important for overall function of the knee. Our preferred repair method utilizes a two-tunnel transtibial pull-out technique. Superior and inferior branches of the medial and lateral geniculate arteries supply the peripheral third of the menisci via the perimeniscal capillary plexus.3,4, Meniscal tears occur due to a shear force between the femur and tibia. This is the most common type of meniscus tear. 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. There are numerous types of meniscus tears, including: 1. Clinical: Most trauma to knee joint is caused by a lateral blow at knee level when foot is planted when knee is slightly flexed. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Meniscus tears are injuries that occur in the cartilage of the knee. Thessaly test: The clinician holds the patient's outstretched hands for support, while the patient stands flat-footed with their knee flexed to 20 degrees and rotates their body and knee three times, internally and externally. Results: Medial meniscus posterior horn longitudinal tears in ACL-deficient knees resulted in a significant increase in anterior-posterior tibial translation at all flexion angles except 90 (P < .05). 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. Meniscus surgery is a common operation to remove or repair a torn meniscus, a piece of cartilage in the knee. Nonsteroidal anti-inflammatory drugs (NSAIDs), Inability to move your knee through its full range of motion. A lateral meniscus tear (torn meniscus) is a tear of the semicircular fibrous cartilage discs in the knee. This part of the tibia is also known as the tibial plateau. Patients are often aware of movements that aggravate mensical pain, but should also be educated to avoid twisting on a weight bearing, flexed knee. The joint is fairly flexible only the last 10-15 degrees is painful, but the pain on walking constant and vulnerable to . De Carlo M, Armstrong B. Bucket-handle tears are actually a form of longitudinal tear in which subsequent displacement of the inner rim of the tear results in a configuration that resembles the handle of a bucket (11a). If a repair is attempted within meniscal tissue that is questionably vascular or non-vascular, healing enhancement techniques such as the use of fibrin clot and the creation of channels that communicate with the vascular zone may be utilized.10. Ercin E, Kaya I, Sungur I, Demirbas E, Ugras AA, Cetinus EM. Although rarely taught and poorly utilised, recent validation demonstrated a sensitivity of 90%, and specificity of 98% in detecting meniscal injury.10, If clinically suspicious of meniscal injury, a trial of conservative measures may be considered or confirmation with magnetic resonance imaging (MRI). This means that athletes, especially those who participate in contact sports like football, are at a higher risk of sustaining this injury. Non-anatomic placement of a PCL reconstruction tibial tunnel is a reported cause of iatrogenic medial meniscal posterior root tears. The surgery requires a few small incisions and takes about an hour. 2013. An awkward twist when getting up from a chair may be enough to cause a tear in an aging meniscus. Tears that lie within or contact the red zone are also more likely to be amenable to meniscal repair. This often causes the knee to become stuck due to a portion of the meniscus blocking the knees normal motion. In this short surgical video, a degenerative meniscus tear is smoothed down with a motorized shaver during a partial meniscectomy. Every care is taken to reproduce articles accurately, but the publisher accepts no responsibility for errors, omissions or inaccuracies contained therein or for the consequences of any action taken by any person as a result of anything contained in this publication. w/severe pain? Coronal proton weighted MRI of horizontal tear of lateral meniscus (white arrow) with complicating ganglion (black arrow) at the lateral margin of the meniscus, Australian Family Physician was the peer-reviewed, scholarly journal of The Royal Australian College of General Practitioners (RACGP) from 1971 to 2017. The menisci act as cushions between your shin bone (tibia) and your thigh bone (femur). When a meniscus tear occurs, you may hear a popping sound around your knee joint. A meniscectomy requires less time for healing approximately 3 to 6 weeks. Please note, we cannot prescribe controlled substances, diet pills, antipsychotics, or other abusable medications. (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. The healing time in children is a little less as the healing process is faster in children than in adults. Because the pieces cannot grow back together, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically. Think before you speak. Normal knee anatomy. It is estimated that only 10% of the injuries involving the tear of posterior horn medial meniscus are repairable. MR imaging is reliable in the detection of meniscal tears and identification of meniscal fragmentation and displacement [1, 2, 3, 4].Displaced meniscal fragments are often clinically significant lesions requiring surgical intervention and, therefore, are important to identify. Meniscus tears, indicated by MRI, are classified in three grades. Mri of knee shows "oblique tear posterior horn medial meniscus, lateral patellar plica and minimal synovial knee effusion" will i need surgery? My husband has complex tear of the body and posterior horn of the medial meniscus with flap components, horizontal oblique tear of the body and posterior horn lateral meniscus. (386) 254-6819, Main Office & Walk-In Clinic One of the most common knee injuries is a torn meniscus. Arthroscopic meniscus repairs typically takes about 40 minutes. Psterior horn of medial meniscus Poterior oblique ligament . Following root repair, patients are required to remain non-weight-bearing for 6 weeks. If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically. The test is positive if symptoms are reproduced on rotation 10. Crawford R, Walley G, Bridgman S, Maffulli N. Magnetic resonance imaging versus arthroscopy in the diagnosis of knee pathology, concentrating on meniscal lesions and ACL tears: a systematic review. Reactive synovitis and edema (arrowheads) are readily apparent deep to the tibial collateral ligament on the coronal view. However, whether they will respond well to surgery depends on the type of tear, the location, and blood flow in the area where the tear occurred. J Bone Joint Surg Am 2005;87:71524. It has the shape of two C's. The medial meniscus is the C shape on the knee's inner side, and the lateral meniscus is the C shape on the outer side of the knee. These tendons have poor blood supply and will not heal themselves. I have an oblique horizontal tear posterior horn medial meniscus, what does that mean? Oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. Surgical treatment is usually reserved for younger patients with a vertical longitudinal tear within the vascularised outer third of the meniscus. Fat suppressed proton density-weighted (15a) coronal and (15b) sagittal images reveal a tibial sided flap tear of the body of the medial meniscus, with displacement of the undersurface component (arrows) into the inferior gutter. Surgery is typically the only option and works to trim the damaged portion of the meniscus. Tears present as severe pain, swelling, and possibly catching, clicking, difficulty on deep knee bending and locking of the knee in partial flexion. Complex degenerative tear. For patients whose procedures have not yet been rescheduled:What to Do If Your Orthopaedic Surgery Is Postponed. Biomaterials 2011;32:741131. Even better would be to describe a peripheral longitudinal tear extending to the tibial surface within the posterior horn of the medial meniscus! MR is also able to assess the stability of meniscal tears,6 an important factor, as unstable tears require operative treatment for symptom relief. As such, it is critical to repair medial meniscal root tears during ACL reconstruction to help stabilize the knee, as well as to decrease stresses that the graft experiences. In case of an open or unstable fracture, the bone may protrude out of the skin surface and be exposed to environmental contaminants. In older patients, referral is appropriate if conservative management fails to improve symptoms. Prospective evaluation of 1485 meniscal tear patterns in patients with stable knees. Knee Surg Sports Traumatol Arthrosc 2011 Aug 11. Meniscal pain occurs during torsional, weight bearing knee movements (classically pivoting on the knee while walking) as a sharp stab lasting several seconds, often followed by a dull ache for several hours. The medial meniscus is the portion of the cartilage along the inside of the knee joint (closest to the other knee). In some cases, a meniscal repair may also be possible, though this is dependent on the size and location of the tear. All material on this website is protected by copyright. How to treat oblique tear of medial meniscus? The majority of these types of tears do not need surgery. 5 Non-Christmas Movies to Watch This Holiday, Best Online Games to Play with your Friends, 12 tips for creating visual content on social media. The second patient reviewed in this video is an 11-year-old girl who fell while playing tag and hit the front of her left lower leg. Perhaps the best know of these is the bucket-handle tear. Rotator Cuff and Shoulder Conditioning Program. The medial meniscus transmits approximately 50% of the total joint load of the knee medial compartment, thus protecting the articular cartilage from excessive force. Sometimes these tears require surgical repair. The knee meniscus: structure-function, pathophysiology, current repair techniques, and prospects for regeneration. Detailed review of funding for diagnostic imaging services. what is the treatment? This region of the outer meniscus, sometimes referred to as the red zone, is thought to occupy approximately 15% of the peripheral meniscus.4 Tears that occur within the red zone of the meniscus are more likely to heal than those in the avascular, white zone of the meniscus. We use cookies to ensure that we give you the best experience on our website. There may be some pain. In this procedure, the surgeon inserts a miniature camera through a small incision (portal) in the knee. 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. Medial meniscal root tears: Fix it or leave it alone Orthopedics Today | Medial and lateral menisci are crescent-shaped fibrocartilage structures that provide joint congruity, stabilization and. 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. 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. During weight-bearing activities, the menisci dissipate axial loads and contain hoop stresses. (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. AJSM 1999; 27:242-250. Sounds like it will not get better without arthroscopic surgery. Scuderi G, Tria A. 2nd edn. Am J Sports Med 2006;34:91927. By using our website, you consent to our use of cookies. If the fracture is stable or closed where the bones do not move out of alignment then simple immobilization with the use of a sling, splint or cast for a few weeks allowing the fracture to heal may be enough. In many cases, rehabilitation can be carried out at home, although your doctor may recommend working with a physical therapist. Also know what the side effects are. It is generally divided into 3 separate portions, the anterior horn, the mid-body and the posterior horn. In cases where surgery is required, this time frame increases to somewhere around three to four months. Explains two kinds of surgery. The meniscus shows up as black on the MRI. There is a history of sudden inability to fully extend the knee, with a rotational flexion/extension 'trick' required to regain full extension. Indications for meniscal root repair are acute, traumatic root tears in patients with nearly normal or normal cartilage (Outerbridge grade 0 to 2) and chronic symptomatic root tears in active patients without significant pre-existing osteoarthritis (OA). If an ACL tear is also present, meniscal repairs are more successful if the ACL is also repaired, likely due to the protection afforded by knee stability. Most people can still walk on their injured knee, and many athletes are able to keep playing with a tear. For these, please consult a doctor (virtually or in person). Those that extend through the entire width of the meniscus are particularly harmful (16a,16b), and even if such tears appear stable following repair, they are unlikely to regain the ability to provide hoop stress to the meniscus.13 Radial tears have therefore classically been treated with partial meniscectomy, though evolving surgical techniques have led to successful reports of the repair of radial tears that communicate with the meniscal periphery.11 A recent report has even described the successful repair of radial tears of the medial meniscal root,14 utilizing a tibial tunnel through which sutures are placed in the avulsed meniscus, a technique similar to that used in patients undergoing meniscal transplantation.
