The majority of these types of tears do not need surgery. Lufkin R. The MRI manual. Tears of the posterior medial meniscal root have shown to disrupt the normal motion of the knee, resulting in degenerative arthritis. In rare cases secondary signs can be seen, such as a soft tissue swelling next to the meniscus when a meniscal cyst is present 4. Typically, complex tears are not treated with meniscus repair due to their complex nature. The operative equipment needs and post-operative rehabilitation process markedly differ between meniscal repair and partial meniscectomy. A medial meniscus tear on the inside of the knee is more common. AJSM 2007; 35:1380-1383. The Royal Australian College of General Practitioners, 100 Wellington Parade, East Melbourne, Victoria 3002, Australia. Chahla and Geeslin report no relevant financial disclosures. Meniscal tears often occur in young patients who have suffered a twisting injury to 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. Sometimes conservative treatment doesnt work. 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. 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. (386) 255-4596 Likewise, physical exam findings of an effusion, a positive McMurray test and a positive Apley grind test are not usually present. Medial meniscal root tears are radial tears within 1 cm of the meniscal root insertion or an avulsion of the insertion of the meniscus. Because other knee injuries can cause similar symptoms, your doctor may order imaging tests to help confirm the diagnosis. Medial meniscal posterior root tears represent an often unrecognized pathology with potentially devastating long-term effects. With the realization that even partial meniscectomy leads to accelerated osteoarthritis,2 surgeons have increasingly turned to meniscal repair. from the American Academy of Orthopaedic Surgeons, Questions and Answers for Patients Regarding Elective Surgery and COVID-19. Walking can become difficult. RICE stands for Rest, Ice, Compression, and Elevation. what is the treatment? 2023 The Orthopedic Clinic. All rights reserved. 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. https://www.webmd.com/pain-management/knee-pain/meniscus-tear-injury Know the reason for your visit and what you want to happen. Complex tears like this are likely to be unstable. Oblique tears commonly cause flaps and flaps are generally not good. Injury, degeneration, or surgical removal of all or part of the meniscus is associated with an increased risk of developing knee osteoarthritis. 1890 LPGA Blvd., Suite 240 Daytona Beach, FL 32117, Port Orange North & South Helms CA, Laorr A, Cannon WD, Jr. This is because this area has rich blood supply and blood cells can regenerate meniscus tissue or help it heal after surgical repair. The clinician applies axial pressure to the foot and rotates the tibia internally and externally. 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- . w/severe pain?

The amount of pain and first appearance of swelling can give important clues about where and how bad the injury is. (13a) A coronal image from another patient with a medial meniscal root tear demonstrates associated severe medial subluxation of the meniscal body (arrow). The tear results in a vertical signal abnormality on sagittal MR images. They are most frequently seen at the posterior horn of the medial meniscus. (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. Repair of such lesions can result in dramatic clinical as well as MR imaging results (17a,17b). Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites. apalia R, Del Buono A, Osti L, Denaro V, Maffulli N. Meniscectomy as a risk factor for knee osteoarthritis: a systematic review. Scuderi G, Tria A. Procedure. Submission to the Department of Health and Ageing. Sources: With regard to tear morphology, the classic ideal candidate for meniscal repair is the peripheral longitudinal tear. 1 Sutton JB. Now, 49 I have had intense pain 2 days after a 3 hour steep mountain walk- the first in 6 months. Parrot Beak Tear: MRI Proton weighted sagittal image demonstrates an example of a posterior horn medial meniscal horizontal tear (white arrow). De Carlo M, Armstrong B. The most common symptom of a torn meniscus is localized pain in the knee that worsens when rotating the leg. An MRI scan assesses the soft tissues in your knee joint, including the menisci, cartilage, tendons, and ligaments. For patients requiring meniscectomy, meniscal autograft has been utilised with good outcomes,2931 but is only performed in specialist centres. This often causes the knee to become stuck due to a portion of the meniscus blocking the knees normal motion. AJR 2000; 174:161-164. Herrlin S, Hallander M, Wange P, Weidenhielm L, Werner S. Arthroscopic or conservative treatment of degenerative medial meniscal tears: a prospective randomised trial. American Board of Orthopaedic Surgery Practice of the Orthopaedic Surgeon: Part-II, certification examination case mix. Question options: . . All rightsreserved. Can a torn meniscus heal by itself? oblique ligament, and the . These can occur through either a contact or non-contact injury for example, a pivoting or cutting injury. (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. The anterior horn of the medial meniscus demonstrates half of the normal anatomic 'bow-tie configuration'. Solomon L, Warwick D, Nayagam S. Apley's Concise System of Orthopaedics and Fractures. Clinical outcomes following isolated lateral meniscal allograft transplantation. 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. What to Do If Your Orthopaedic Surgery Is Postponed. 13 Newman AP, Daniels AU, Burks RT. The primary objective is to control the disease process to avoid the complications . Successful outcome and patient satisfaction after medial meniscal root repair are established initially upon appropriate diagnosis and patient selection. (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. 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. Although an X-ray will not show a meniscus tear, your doctor may order one to look for other causes of knee pain, such as osteoarthritis. type 3, vertical longitudinal bucket-handle tears; type 4, complex oblique tears; and type 5, bone avulsion fractures of the root attachments. There will also be skin discoloration and visible deformity at the site of the injury. Detailed review of funding for diagnostic imaging services. These are the horns. These tears often occur in association with ACL tears, but even if found in isolation, are highly likely to be clinically relevant, as the displaced meniscal fragment frequently results in knee locking. If you have unusual pain and discomfort in your knee, let us help you get back to doing the things you love. This type of tear has an unusual pattern. Surgery is most likely needed to resolve your problem. Most oblique meniscus tears are happen in the posterior third of the medial meniscus. Performing activities that involve aggressive pivoting and twisting of the knee puts you at a significantly higher risk of tearing your meniscus. Arthroscopic partial meniscectomy The goal of this surgery is to remove a small piece of the torn meniscus in order to get the knee functioning normally. This is the most common type of meniscus tear. Patients describe meniscal tears in a variety of ways. Sports-related meniscus injuries often occur along with other knee injuries, such as anterior cruciate ligament (ACL) tears. Arthroscopy 2010;26:13689. and oblique tear . If you are having pain, swelling and catching, then the only reasonable option would be arthroscopic knee surgery. The treatment may be conservative or sometimes surgery may be required to treat the fracture. Orthopedics 2009;32:8. 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. Still, many people with a torn meniscus can walk, stand, sit, and sleep without pain. Even better would be to describe a peripheral longitudinal tear extending to the tibial surface within the posterior horn of the medial meniscus! All rights reserved. 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 ]. This often signals a tear. Meniscal tears within the body of the meniscus or at the meniscocapsular junction represent a well-understood and manageable condition encountered in clinical practice. 7 Yao L, Stanczak J, Boutin RD. 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. Garrett WE Jr, Swiontkowski MF, Weinstein JN, et al. Because the pieces cannot grow back together, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). If the tear cant be repaired, occasionally the meniscus can be surgically trimmed. Knee Surg Sports Traumatol Arthrosc 2009;17:11026. Grades 1 and 2 are not considered serious. The procedure begins with a complete diagnostic arthroscopy using a 30-degree arthroscope. Operative Arthroscopy, 3rd Edition, 2002, Lippincott Williams and Wilkins. Disclosures: LaPrade reports he is a consultant for and receives royalties from Arthrex, Ossur and Smith & Nephew. Progressive weight-bearing begins at 6 weeks, with full weight-bearing at 8 weeks. A tear of the anterior horn of the lateral meniscus is damage to the front part of one of the two structures that act as shock absorbers between the thigh bone and the lower leg, explains The Steadman Clinic. We believe these tears are more degenerative in nature, and there is no evidence to support that by repairing these medial meniscal root tears, knee degeneration will be postponed or stopped. Sekiya JK, West RV, Groff YJ, Irrgang JJ, Fu FH, Harner CD. The medial meniscus has a firmer capsular attachment than the lateral meniscus. 4 Hauger O, Frank LR, Boutin RD, et al. 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. AJR 2001; 176:771-776. AnteroLateral Meniscus Tear: This means your lateral meniscus is torn and in a location on the front portion of the knee. In this procedure, the surgeon inserts a miniature camera through a small incision (portal) in the knee.

Additionally, the individual will not be able to move the joint due to pain. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. 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). We use cookies to ensure that we give you the best experience on our website. At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Extrusion of the medial meniscus (MM) is associated with knee joint pain in osteoarthritic knees. OKeefe R, et al. Arthroscopic treatment is typically required for adequate symptom relief in patients with displaced meniscal flap tears. An MRI is 70 to 90 percent accurate in identifying whether the meniscus has been torn and how badly. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. 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 . Medial meniscal root tears are more frequently diagnosed in patients who are older than 40 years, are overweight and cannot recall an inciting event. The best known displaced tear that is amenable to repair is the bucket-handle tear. A loose piece of cartilage can get stuck in the joint, causing the knee to temporarily lock, preventing full extension of the leg. You will start with exercises to improve your range of motion. Many meniscus tears will not need immediate surgery. Mui LW, Engelsohn E, Umans H. Comparison of CT and MRI in patients with tibial plateau fracture: can CT findings predict ligament tear or meniscal injury? In some cases, your doctor may suggest an arthroscopyto examine and possibly treat your knee. I could not really walk on it. However, anyone at any age can tear the meniscus. Meniscal tears are common sports-related injuries in young athletes and can also present as a degenerative condition in older patients. Presumptive subarticular stress reactions of the knee: MRI detection and association with meniscal tear patterns. 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. 3rd edn. Note: the cartilage deficit more anteriorly on the medial femoral condyle and altered subchondral cortical bone interface, Figure 5. In this case, a portion may break off, leaving frayed edges. Younger and elderly patients typically sustain different types of tears.

Tell your doctor of any recurrent swelling or of your knee repeatedly giving way. 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. While visualization of the meniscal root may be difficult due to MRI slice size, type of MRI and strength of MRI, an extrusion larger than 3 mm highly correlates with a root tear. If you undergo surgery it will likely be followed by physical therapy to optimize knee strength and stability. https://www.verywellhealth.com/types-of-meniscus-tears-3862073, https://www.webmd.com/pain-management/knee-pain/meniscus-tear-injury, https://orthop.washington.edu/patient-care/articles/sports/torn-meniscus.html, A sensation that the knee is locked in place. The meniscus is broken down into the outer, middle, and inner thirds. Anti-inflammatory drugs such as aspirin, ibuprofen, and naproxen help reduce pain and swelling. It is important to describe your symptoms accurately. Meniscus tears are injuries that occur in the cartilage of the knee. Clin Orthop Related Res 2010;468:11902. Although C, a vertical tear, is commonly used to describe such an appearance, the better answer is D, a longitudinal tear. Absence of the medial meniscus (entire medial meniscal root tear) places large stresses on the ACL, the primary ligament that prevents anterior translation of the knee. Develop pain gradually along the meniscus and joint line when you put stress on your knees (usually during a repeated activity). 2010. Your doctor will bend your knee, then straighten and rotate it. Knowing where and how a meniscus was torn helps the doctor determine the best treatment.. Repair is sometimes attempted even with these tear types, particularly when the patient is young and substantial loss of meniscal tissue would lead to an unacceptable risk of future arthritis.11 Repair of these challenging tear types should only be attempted when the meniscal tissue is of good quality and a stable result is achievable. Without nutrients from blood, tears in this "white" zone with limited blood flow cannot heal. Each knee has two C-shaped pieces of cartilage known as menisci. Principles and decision making in meniscal surgery. Non-operative treatment of degenerative posterior root tear of the medial meniscus. Cole BJ, Dennis MG, Lee SJ, et al. 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. In many cases, rehabilitation can be carried out at home, although your doctor may recommend working with a physical therapist. If your meniscus tear is not severe, your doctor will likely recommend the following treatment: If you have a meniscus tear, physical therapy can help to strengthen the muscles around the knee as well the muscles in your legs which in turn will stabilize and support the knee. Any tears appear as white lines. However, meniscus tears do not always appear on MRIs. When appropriate, tears that appear to involve the periphery, or red zone of the meniscus, should be described as such (9a), thereby alerting the surgeon to the fact that the tear is more amenable to repair. 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. https://orthop.washington.edu/patient-care/articles/sports/torn-meniscus.html, Phone Includes interactive tool to help you decide. Description of Medial Meniscus Tear The medial meniscus is an important shock absorber on the inside (medial) aspect of the knee joint. These are the menisci. Aged, worn tissue is more prone to tears. 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. One of the main tests for meniscus tears is the McMurray test. Both of them have 2 causes. Adjunctive measures to promote vascularity and healing at the repair sites are also recommended. Know why a test or procedure is recommended and what the results could mean. Ask if your condition can be treated in other ways. Ligaments: their nature and morphology.
