Patients describe meniscal tears in a variety of ways. Each knee joint has two crescent-shaped cartilage menisci. Also write down any new instructions your provider gives you. As stated above, the most common cause of Posterior Horn Medial Meniscus Tear can be trauma to the knee which can be sustained due to a sporting injury, a slip and fall, a blunt trauma to the knee, and in majority of the cases natural degeneration of the meniscus due to the work load of the knee. Knee Surg Sports Traumatol Arthrosc 2007;15:393401. Connect with a U.S. board-certified doctor by text or video anytime, anywhere. Question options: . In many cases, rehabilitation can be carried out at home, although your doctor may recommend working with a physical therapist. 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. Aging is also a risk factor due to general wear and tear of the knees. Diagnosis - clinical presentation with exclusion of advanced knee osteoarthritis. The posterior horn is the thickest and most important for overall function of the knee. what is the treatment for that? This type of tear is particularly devastating to meniscal function. When people talk about torn cartilage in the knee, they are usually referring to a torn meniscus. 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. controlling the movements of the knee joint. Clinical: Most trauma to knee joint is caused by a lateral blow at knee level when foot is planted when knee is slightly flexed. Sometimes, its possible to repair a torn meniscus, especially if you are a young adult. They will also consider the type, size, and location of the injury. 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. Chronic tears may be scarred to the capsule and require release of the meniscocapsular junction to allow anatomic repair. OKeefe R, et al. 9 Lecase LK, Helms CA, Kosarek FJ, Garret WE. The role of preoperative MRI in knee arthroscopy: a retrospective analysis of 2,000 patients. 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. Displacement of the inner rim of the tear (arrowheads) results in the classic "bucket-handle" configuration. Location -A tear may be located in the anterior horn, body, or posterior horn.A posterior horn tear is the most common. I have an oblique tear of the posterior horn of my medial meniscus that extends to the undersurface of the cartilage. 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. Because there is no supply, there is little capacity for these tears to heal on their own. This puts tension on a torn meniscus. I have a oblique grade 3 tear posterior horn of the medial meniscus. The younger population, particularly males with knee instability, is most commonly affected by this type of tear [56]. Herrlin S, Hallander M, Wange P, Weidenhielm L, Werner S. Arthroscopic or conservative treatment of degenerative medial meniscal tears: a prospective randomised trial. The body usually absorbs these over time. New advances in musculoskeletal pain. This often causes the knee to become stuck due to a portion of the meniscus blocking the knees normal motion. Meniscal tears are the most common lesions followed by the meniscal cyst. Mri of knee shows "oblique tear posterior horn medial meniscus, lateral patellar plica and minimal synovial knee effusion" will i need surgery? True locking is less common, and suggests a bucket-handle tear, with the torn fragment preventing full extension. You might develop the following signs and symptoms in your knee: A popping sensation. This information is not intended as a substitute for professional medical care. This opening pushes the inside edge of your meniscus toward the middle of your knee. The healing time in children is a little less as the healing process is faster in children than in adults. They act as shock absorbers and stabilize the knee. Not all meniscal tear types, however, are amenable to repair, and thus an accurate description of meniscal tears on MR can have a dramatic impact on preoperative planning. M23.322 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The Royal Australian College of General Practitioners. The McMurray test (shown here) will help your doctor determine if you have a meniscus tear. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Although the . This is a large horizontal tear of the meniscus. Develop pain gradually along the meniscus and joint line when you put stress on your knees (usually during a repeated activity). a feeling that your knee is catching or locking, usually when it's bent - you may notice it clicking. 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 . The preferred nomenclature for this tear pattern is: A gradient-echo T2*-weighted sagittal image, A. Each knee has two C-shaped pieces of cartilage known as menisci. he is 44 y o tennis player. Grades 1 and 2 are not considered serious. A lateral meniscus tear (torn meniscus) is a tear of the semicircular fibrous cartilage discs in the knee. Tears should be characterized with regard to morphology, size, location, and stability, all of which are important factors that may influence the choice of operative treatment. I have an oblique horizontal tear posterior horn medial meniscus, what does that mean? Many meniscus tears will not need immediate surgery. 17 Old Kings Road N., Suite K Palm Coast, FL 32137, East Coast Surgery Center The Thessaly test is the most sensitive and specific clinical test to diagnose meniscal injury. (Lateral one = ACL, medial one= chondral injury) Medial and lateral menisci are crescent-shaped fibrocartilage structures that provide joint congruity, stabilization and lubrication and act as shock absorbers for joint preservation. The absent bow tie sign in bucket-handle tears of the menisci in the knee. The menisci the medial meniscus and lateral meniscus - are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). AJR 1998;170:63-67. Physiotherapy at two visits per week for at least 8 weeks is recommended.20 There is little evidence for strapping of meniscal injuries and this is not currently recommended. With the realization that even partial meniscectomy leads to accelerated osteoarthritis,2 surgeons have increasingly turned to meniscal repair. Progressive weight-bearing begins at 6 weeks, with full weight-bearing at 8 weeks. Additionally, the large radial tear dramatically undermines the ability of the meniscus to distribute hoop stress. Radiographs may or may not show medial joint space narrowing. Both longitudinal and radial tears may appear vertical on MR images (5a,6a), but longitudinal tears extend parallel to the c-shaped circumference of the meniscus, whereas radial tears lie perpendicular to the meniscal circumference. 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. 7 Yao L, Stanczak J, Boutin RD. The device is small and contains a light and a camera, which transmits images from inside the knee onto a monitor. Studies have also reported that patients who underwent a repair of the posterior root in the medial meniscus slowed the progression of arthritic changes compared with those who had a meniscectomy; although, this did not completely prevent the arthritic changes. Once the initial healing is complete, your doctor will prescribe rehabilitation exercises. 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. 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. These can occur through either a contact or non-contact injury for example, a pivoting or cutting injury. Because the pieces cannot grow back together, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically. A tear in this "red" zone may heal on its own, or can often be repaired with surgery. In fact, the tear will most likely get bigger leading to additional damage if not taken care of soon. Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. An oblique tear (7a,8a) is often referred to as a parrot-beak tear, as the tear shape resembles a parrots beak. The parrot beak shape of an oblique tear (arrow) is readily apparent on (7a) a proton density-weighted axial image of the menisci. Great Britain: Hodder Arnold, 2005. A 501(c)(3) non-profit organization. Principles and decision making in meniscal surgery. Recovery and rehabilitation take a few weeks. I have an oblique tear of the posterior horn and body of the medial meniscus extending to the inferior articular surface. Collateral and cruciate ligaments are intact. Arthroscopic treatment is typically required for adequate symptom relief in patients with displaced meniscal flap tears. It absorbs shock in your knee and keeps it stable. McMurray (Figure 1) and Apley tests (Figure 2) are often positive, although these are specific but not sensitive specificity being 5798% and 8099%, and sensitivity being 1066% and 1658% respectively.2,9 The most useful clinical test for meniscal injury is the Thessaly test, which is demonstrated in Figure 3. 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. Call us today at (410) 644-1880 or (855) 4MD-BONE (463-2663) to schedule an appointment. Meniscal repair surgeries do the best when the meniscal tear extends into the middle 50% of meniscal substance. Tears that are stable, < 1 cm in length, and that do not cause significant . Bull NYU Hosp Jt Dis 2010;68:8490. can he still play tennis with this injury? type 3, vertical longitudinal bucket-handle tears; type 4, complex oblique tears; and type 5, bone avulsion fractures of the root attachments. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. The majority of these types of tears do not need surgery. See your ortho for an evaluation. Meniscal repair using an exogenous fibrin clot. 2023 Cedars-Sinai. Non-anatomic placement of a PCL reconstruction tibial tunnel is a reported cause of iatrogenic medial meniscal posterior root tears. When small, conservative therapy or simply rasping the meniscus may result in healing of these tear types. In addition to the root tear, the MRI often shows chondral loss or fissuring, other areas of meniscal tearing, bone marrow edema or osteophyte formation (Figure 5). Sports-related meniscus injuries often occur along with other knee injuries, such as anterior cruciate ligament (ACL) tears. With meniscal repair, weight bearing may be severely limited for up to six weeks following surgery, and protection from heavy stress to the knee extends for up to six months. The medial meniscus is the portion of the cartilage along the inside of the knee joint (closest to the other knee). In cases where a torn meniscus has locked the knee, walking will be affected. (12a) A radial tear (arrow) truncates the central attachment/root of the posterior horn of the medial meniscus on this fat suppressed proton density-weighted coronal image. With proper diagnosis, treatment, and rehabilitation, patients often return to their pre-injury abilities. Nonoperative treatments are an important part of the management of all patients, regardless of whether surgery is being considered. Harrison BK, Abell BE, Gibson TW. If your symptoms persist with nonsurgical treatment, your doctor may suggest arthroscopic surgery. Symptomatic treatment with rest, ice, NSAIDs and/or an unloader brace may help alleviate symptoms in some cases. As people age, they are more likely to have degenerative meniscus tears. MRI scans show (left) a normal meniscus and (right) a torn meniscus. Patients with ACL tears are also thought to be better candidates for meniscal repair because of the presence of serum-derived growth factors within the hemarthrosis that accompanies ACL tears.15. tears of the medial meniscus were the most common type oftear,comprising40%ofmedialmeniscustears.Further-more, more than 75% of medial meniscal tears in the ACL- . The goal of meniscal root repair is to restore the joint to a near native function of the meniscus and prevent cartilage degradation associated with nonsurgical treatment or meniscectomy. Vertical flap (oblique, flap, parrot's beak) tears are unstable tears and occur in younger patients. Pain is typically medial and activity-related (e.g. Top answers from doctors based on your search: Created for people with ongoing healthcare needs but benefits everyone. 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). Longitudinal tears do not disrupt the circumferential architecture of the meniscus, and thus repair of longitudinal tears leads to a meniscus with relatively normal biomechanical function. It has been reported that the force experienced by the medial meniscus in the ACL-deficient knee increased by 52% in full extension and by 197% at 60 of flexion under a 134-N load. [Epub ahead of print]. 1871 LPGA Blvd., Daytona Beach, FL 32117. Sources: A meniscus tear is an injury to one of the bands of rubbery cartilage that act as shock absorbers for the knee. https://www.webmd.com/pain-management/knee-pain/meniscus-tear-injury Most likely, your doctor will recommend that you rest, use pain relievers, and. oblique ligament, and the . Meniscus Repair. An MRI scan assesses the soft tissues in your knee joint, including the menisci, cartilage, tendons, and ligaments. In comparison , however, meniscal root tears (MRTs) often go unnoticed and represent a unique injury pattern with unique biomechanical consequences. Nourissat G, Beaufils P, Charrois O, et al. Sekiya JK, West RV, Groff YJ, Irrgang JJ, Fu FH, Harner CD. Younger and elderly patients typically sustain different types of tears. Orthopaedic Basic Science: Foundation of Clinical Practice. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. Many tears are repaired with dartlike devices that are inserted and placed across the tear to hold it together. 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. A meniscus tear can occur when the knee is suddenly twisted while the foot is planted on the ground. It is therefore quite important in treatment planning for the pre-operative MR to provide information that can be used to determine whether meniscal repair rather than partial meniscectomy is to be performed. 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. Also know what the side effects are. 1890 LPGA Blvd., Suite 240 Daytona Beach, FL 32117, Port Orange North & South The medial meniscus is an important secondary stabilizer of the knee. These are the menisci. A recent study demonstrated 46% of patients with degenerative meniscal tears elected not to have surgery after 4 weeks of nonoperative treatment, and their functional improvement matched patients in the operative group.21 Another study of degenerative tears demonstrated that supervised exercise caused the same reduction in knee pain and the same increase in function and satisfaction as partial meniscectomy plus exercise.23 As degenerative tears are more common in elderly patients, this group is more likely to respond to conservative treatment. (3a) A fat-suppressed proton density-weighted axial image through the knee joint demonstrates the C-shaped menisci. In contrast, the inner two-thirds of the meniscus lacks a significant blood supply. Submission to the Department of Health and Ageing. and oblique tear . Treatment for a meniscus tear will depend on its size, what kind it is, and where it's located within the cartilage. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. Printed from Australian Family Physician - https://www.racgp.org.au/afp/2012/april/meniscal-tear The Australian College of General Practitioners www.racgp.org.au, AJGP: Australian Journal of General Practice, https://www.racgp.org.au/afp/2012/april/meniscal-tear, shock absorption and distributing load throughout the joint, providing nutrition for articular cartilage. What is Meniscus Radial Tear. How can I tell if I have an oblique fracture? Acute meniscus tears often happen during sports. Depending on the cut thickness, axial MRI images may display the root tear (Figure 3). Sometimes these tears require surgical repair. There are numerous types of meniscus tears, including: 1. The test is positive if symptoms are reproduced on rotation 10. Torn meniscus symptoms Symptoms are usually sudden onset, however, can develop gradually over time. Call us at(386) 255-4596to schedule an appointment. 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. Immediate conservative measures include the RICE regimen: Longer term measures include activity modification, nonsteroidal antiinflammatory drugs (NSAIDs) and physiotherapy.4,1921 Nonsteroidal anti-inflammatory drugs are often recommended for 812 weeks,20 although paracetamol can be considered if NSAIDs are contraindicated or poorly tolerated.22 Where available, intensive physiotherapy is very useful and should include range of motion, proprioceptive work and muscle strengthening exercises. The posterior horn it the back portion of the menisci at the end of the curve, where it tapers . what is the treatment? This most often happens when the tear develops over a period of time. If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically. AJSM 2003; 31:216-220. 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. Afterward, you may experience: pain, especially when the area is touched. Barrett GR, Field MH, Treacy SH, Ruff CG. Explains two kinds of surgery. Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites. For patients requiring meniscectomy, meniscal autograft has been utilised with good outcomes,2931 but is only performed in specialist centres. Horizontal cleavage, oblique, and complex meniscal tear patterns have traditionally been poor candidates for meniscal repair. 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). This means that athletes, especially those who participate in contact sports like football, are at a higher risk of sustaining this injury. pivoting). Meniscus tears can happen during physical activities, but they can also occur from: Sometimes, a torn meniscus can occur due to degenerative changes in the knee, even if there is little to no trauma. The first one is traumatic and the second one is a degenerative meniscal tear. It is important that these root avulsions are anatomically repaired back to the bone. Know the reason for your visit and what you want to happen. https://orthop.washington.edu/patient-care/articles/sports/torn-meniscus.html, Phone Medial meniscal posterior root tears represent an often unrecognized pathology with potentially devastating long-term effects. The loss of the central attachment of the posterior horn may allow extrusion of the body of the meniscus relative to the joint (13a). Am J Sports Med 2008;36:12839. Research is currently investigating the possibility of implantation of collagen, allogenic and xenogenic cells, embryonic and adult stem cells, or scaffolds derived from polymers, hydrogels, tissues and extracellular matrix,7 and action of biological stimuli (eg. The knee: a comprehensive review. . (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. These are paraphrased. Larger, unstable tears of this type often cause mechanical symptoms, however, and therefore warrant operative treatment, usually via partial meniscectomy. 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. Psterior horn of medial meniscus Poterior oblique ligament . Note: the cartilage deficit more anteriorly on the medial femoral condyle and altered subchondral cortical bone interface, Figure 5. The tear results in a vertical signal abnormality on sagittal MR images. To learn more, please visit our. This provides a clear view of the inside of the knee. This part of the tibia is also known as the tibial plateau. The operative equipment needs and post-operative rehabilitation process markedly differ between meniscal repair and partial meniscectomy. Two bones meet to form your knee joint: the femur and the tibia. Can a torn meniscus heal by itself? 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. 4 Hauger O, Frank LR, Boutin RD, et al. This is the most common type of meniscus tear. So the injury as seen in MRI scan means there is an tear in the medial meniscus towards the posterior side, that is towards the back of joint. 12 Sources By Jonathan Cluett, MD Medial Meniscus: oblique tear of the posterior portion with a separated and unstable fragment. Posterior medial meniscal root tears are often times degenerative, but these can also occur with multi-ligament knee injuries in the acute setting. The anatomic landmark for repair is anterior to the PCL footprint on the tibia. The menisci are "wedge-shaped" pieces of cartilage that rest between the thigh bone ("femur") and lower leg bone ("tibia") in the knee joint. You may be asked about your physical and athletic goals to help your doctor decide on the best treatment for you. (Right) Flap tear. Meniscal tear configurations: categorization with MR imaging. Fax The arthroscope is inserted near the knee via a tiny incision. 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. Meniscus Surgery. All rights reserved. Full thickness tears are the complete disruption of the fibers of the supraspinatus muscle, and generally require a more aggressive treatment plan and surgery. As orthopaedic surgeons increasingly consider meniscal repair, accurate pre-operative assessment with MR becomes more important, allowing proper planning on the part of both the surgeon and the patient. 3 Thornton DD, Rubin DA. A meniscectomy requires less time for healing approximately 3 to 6 weeks. For potential or actual medical emergencies, immediately call 911 or your local emergency service. However, anyone at any age can tear the meniscus. An awkward twist when getting up from a chair may be enough to cause a tear in an aging meniscus. Meniscus tears are among the most common knee injuries. 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. Meniscal ramp lesions can be defined as longitudinal vertical and/or oblique peripheral tears affecting posterior horn of medial meniscus, in a mediolateral direction of less than 2.0 cm, that may lead to meniscocapsular or meniscotibial disruption [ 1 ]. Referral is also indicated if the diagnosis is uncertain for review and to access MRI. The ghost sign or absence of an identifiable meniscus anterior to the posterior cruciate ligament is also indicative of a root tear (Figure 2). In sports, a meniscus tear usually happens suddenly. Dr. Warren Strudwick answered Sports Medicine 32 years experience See your doc: Sounds like it will not get better without arthroscopic surgery. The primary objective is to control the disease process to avoid the complications . 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. for a 22 year old severe pain. Typically, complex tears are not treated with meniscus repair due to their complex nature. Br Med Bull 2011;2011:89106. A meniscus tear can occur when the knee is suddenly twisted while the foot is planted on the ground. Another exam finding is palpating the anteromedial joint line, while placing a varus stress on a fully extended knee and feeling for meniscal extrusion. Scuderi G, Tria A. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. If the tear cant be repaired, occasionally the meniscus can be surgically trimmed. See this post to learn more about how a meniscus functions . Meniscal tears are common sports-related injuries in young athletes and can also present as a degenerative condition in older patients. This presents with a combination of tear patterns. 5 Horizontal tears, the most common meniscal tear pattern, lie parallel to the tibial plateau and separate the meniscus into upper and lower parts (4a,4b). Successful outcome and patient satisfaction after medial meniscal root repair are established initially upon appropriate diagnosis and patient selection. Pathology - a tear that has developed gradually in the meniscus. If your doctor suspects a torn meniscus, he or she will perform aphysicalexam. Knee Surg Sports Traumatol Arthrosc 2011 Aug 11. The medial meniscus is the cushion that is located on the inside part of the knee. Includes interactive tool to help you decide. The outer one-third of the meniscus has a rich blood supply. Skeletal Radiol 2007;36:14551. 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.
