American Board of Orthopaedic Surgery Practice of the Orthopaedic Surgeon: Part-II, certification examination case mix. 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. Evaluate the TCO of your PACS download >, 750 Old Hickory Blvd, Suite 1-260Brentwood, TN 37027, Focus on Musculoskeletal and Neurological MRI, The Anterior Meniscofemoral Ligament of the Medial Meniscus, Collateral Ligament Injuries of the Fingers. Recent kinematic/biomechanical studies have also shown the importance of the medial meniscus to anterior translation of the knee. 2nd ed. Repair of such lesions can result in dramatic clinical as well as MR imaging results (17a,17b). 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. Nonsteroidal anti-inflammatory drugs (NSAIDs). This is because this area has rich blood supply and blood cells can regenerate meniscus tissue or help it heal after surgical repair. The accuracy of physical diagnostic tests for assessing meniscal lesions of the knee: a meta-analysis. Coronal MRI sequences are generally considered the best images for visualization of medial meniscal root tears (Figure 1). growth factors) on meniscus tissue is being investigated.2 These are currently only being trialled in younger patients7 and the routine use of most of these technologies is some time away. 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. 15 Koski JA, Ibarra C, Rodeo SA. Meniscus surgery is a common operation to remove or repair a torn meniscus, a piece of cartilage in the knee. Injury, degeneration, or surgical removal of all or part of the meniscus is associated with an increased risk of developing knee osteoarthritis. It is estimated that only 10% of the injuries involving the tear of posterior horn medial meniscus are repairable. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites. Because a torn meniscus is made of cartilage, it won't show up on X-rays. This most often happens when the tear develops over a period of time. Oblique tears give rise to flaps which are mechanical unstable and associated with mechanical symptoms. Dr. Warren Strudwick answered Sports Medicine 32 years experience See your doc: Sounds like it will not get better without arthroscopic surgery. A lateral meniscus tear (torn meniscus) is a tear of the semicircular fibrous cartilage discs in the knee. The primary objective is to control the disease process to avoid the complications . Pain is typically medial and activity-related (e.g. Solomon L, Warwick D, Nayagam S. Apley's Concise System of Orthopaedics and Fractures. The vascularity of the peripheral menisci is primarily derived from the The tear results in a vertical signal abnormality on sagittal MR images. The joint is fairly flexible only the last 10-15 degrees is painful, but the pain on walking constant and vulnerable to . 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. 1175 Dunlawton Ave., Suite 101, Port Orange, FL 32127, Palm Coast How to Treat Posterior Horn Medial Meniscus Tear. 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. The meniscus can tear from acute trauma or as the result of degenerative changes that happen over time. Question options: . The identification of the meniscus comma sign . AAOS does not endorse any treatments, procedures, products, or physicians referenced herein.

Also know what the side effects are. Jul 2000;35(3):217-30. Tears are typically vertical in young patients and horizontal in the elderly (Figure 5). For potential or actual medical emergencies, immediately call 911 or your local emergency service. There is no resting pain. Seldom are they the sign of a problem. 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. 2013. Making a medial meniscal root tear diagnosis is difficult because the typical history of locking, catching or giving way is less likely to be present. Parrot Beak Tear: MRI Because these two tear patterns differ greatly in prognosis and treatment approach, vertical is therefore not the preferred descriptor for such meniscal tears, unless paired with the proper category, such as vertical longitudinal. This puts tension on a torn meniscus. 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. These tears occur within the avascular zone of the meniscus where there is no blood supply. These imaging pearls improve recognition of meniscal root tears (Figure 2). AJR 2000; 174:161-164. Even better would be to describe a peripheral longitudinal tear extending to the tibial surface within the posterior horn of the medial meniscus! In comparison , however, meniscal root tears (MRTs) often go unnoticed and represent a unique injury pattern with unique biomechanical consequences. Severe pain and swelling may occur up to 24 hours afterward. Oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. Reciprocally, an increased force is also placed on an ACL graft with a deficient medial meniscus. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. 2 Jaureguito JW, Elliot JS, Lietner T. The effects of arthroscopic partial lateral meniscectomy in an otherwise normal knee: a retrospective review of functional, clinical, and radiographic results. Diagnosis can be suspected clinically with joint line tenderness and a positive Mcmurray's test, and can be confirmed with MRI studies. 8 Ruff C, Weingardt J, Russ P, Kilcoyne R. MR imaging patterns of displaced meniscus injuries of the knee. 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. Know why a new medicine or treatment is prescribed, and how it will help you. If you have a follow-up appointment, write down the date, time, and purpose for that visit. Although C, a vertical tear, is commonly used to describe such an appearance, the better answer is D, a longitudinal tear. Biomechanical studies have demonstrated that repair of medial meniscus posterior root tears leads to improved contact mechanics. All material on this website is protected by copyright. De Carlo M, Armstrong B. Ercin E, Kaya I, Sungur I, Demirbas E, Ugras AA, Cetinus EM. The kneecap (patella) sits in front of the joint to provide some protection.

Knee Surg Sports Traumatol Arthrosc 2008;16:4826. 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. The relationships among MM radial/oblique tears, MM extrusion (MME), and the effect of arthroscopic meniscal repair are not established. swelling - this usually happens several hours after you injure your meniscus. 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.

Disclosures: LaPrade reports he is a consultant for and receives royalties from Arthrex, Ossur and Smith & Nephew. Depending on the cut thickness, axial MRI images may display the root tear (Figure 3). Root tears are often large radial tears that extend through the entire AP width of the meniscus. Over 2 to 3 days, however, the knee will gradually become more stiff and swollen. Repair of locked bucket-handle meniscal tears in knees with chronic anterior cruciate ligament deficiency. This tear is usually best seen on the coronal T2-weighted MRI scan (see figure 1), where a fragment of meniscus (black in appearance) is stuck between the medial tibial plateau and the overlying medial collateral ligament.This tear pattern tends to be persistently painful, as the meniscal fragment becomes entrapped between bone and the adjacent soft tissues. Barrett GR, Field MH, Treacy SH, Ruff CG. Strengthening exercises will gradually be added to your rehabilitation plan. Radiographs may or may not show medial joint space narrowing. Arthroscopic repair of isolated meniscal tears in patients 18 years and younger. Vertical flap (oblique, flap, parrot's beak) tears are unstable tears and occur in younger patients. Collateral and cruciate ligaments are intact. https://orthop.washington.edu/patient-care/articles/sports/torn-meniscus.html, Phone 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. Common tears include bucket handle, flap, and radial. Complex or degenerative tears are where two or more tear patterns exist. 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. 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. Br Med Bull 2007;84:523. Medial meniscal posterior root tears represent an often unrecognized pathology with potentially devastating long-term effects.

The anterior horn of the medial meniscus demonstrates half of the normal anatomic 'bow-tie configuration'. Without nutrients from blood, tears in this "white" zone with limited blood flow cannot heal. The meniscus is a piece of C-shaped cartilage that helps cushion the knee. Younger and elderly patients typically sustain different types of tears. The best known displaced tear that is amenable to repair is the bucket-handle tear. Bove SE, Flatters SJ, Inglis JJ, Mantyh PW. Meniscal tear incidence may be as high as six per 1000 population6 with a 2.5 to 4 times male predominance. Magnetic resonance imaging is first line for investigating potential meniscal lesions, but should not replace thorough clinical history and examination. The medial meniscus is on the inner side of the knee joint. 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. The procedure begins with a complete diagnostic arthroscopy using a 30-degree arthroscope. 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. Knee arthroscopy is one of the most commonly performed surgical procedures. Principles and decision making in meniscal surgery. Oblique tears give rise to flaps which are mechanical unstable and associated with mechanical symptoms. Have swelling, stiffness or tightness in your knee. Typically, complex tears are not treated with meniscus repair due to their complex nature. These tears can be challenging to recognize on MRI,9 but are important to diagnose since they are often highly symptomatic due to a reactive synovitis. Many meniscus tears will not need immediate surgery. Depending on the severity of the injury, surgical repair may or may not be needed. Figure 1. 1890 LPGA Blvd., Suite 240 Daytona Beach, FL 32117, Port Orange North & South J Bone J Surg Am 2006;88:6607. 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). (11a) A 3D illustration of a bucket handle tear demonstrates that these tears actually are longitudinal in nature (arrows), coursing parallel to the c-shaped fibers of the meniscus. A meniscus tear is an injury to one of the bands of rubbery cartilage that act as shock absorbers for the knee. for a 22 year old severe pain. In younger patients, this is typically a twisting force on a weightloaded flexed knee. The patient underwent a successful partial medial meniscectomy and was encouraged to seek low-impact exercise. The posterior horn is the thickest and most important for overall function of the knee. Treatment or management protocols for posterior horn menial meniscus tears are quite challenging. 16 OShea JJ, Shelbourne KD. type 3, vertical longitudinal bucket-handle tears; type 4, complex oblique tears; and type 5, bone avulsion fractures of the root attachments. Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. Illustration and photo show a camera and instruments inserted through portals in a knee. Treatment varies on a case-by-case basis. The vertical flap tear is a displaced type of radial tear that often occurs in the posterior medial meniscus. Those with a meniscus tear are also more likely to develop osteoarthritis in the injured knee. 2000-2022 The StayWell Company, LLC. Meniscus tears simply do not heal on their own, regardless of conservative treatment. All rights reserved.

This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. The MRI revealed a vertical flap (oblique) tear of the medial meniscus. This extrusion should disappear without stress. 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. Meniscus Repair. Knowledge of these classifications and the potential contraindications to meniscal root repair can aid the . Orthopedics 2009;32:8. The medial meniscus is the cushion that is located on the inside part of the knee. However, anyone at any age can tear the meniscus. Patients describe meniscal tears in a variety of ways. 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. Guides you through the decision to have surgery for a torn meniscus. A torn meniscus often can be identified during a physical exam. Acute meniscus tears often happen during sports. If your symptoms persist with nonsurgical treatment, your doctor may suggest arthroscopic surgery. 2 The risk of osteoarthritis and its progression increase in line with reductions in tibial cartilage coverage.

These lie on the inside (medial) and outside (lateral) edges of the top of your tibia (shin bone). 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. These are the horns. 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). Meniscal tears often occur in young patients who have suffered a twisting injury to the knee. Pain may wake the patient from sleep as the tender medial aspect of the knee strikes the other side as the patient rolls over in bed. Think before you speak. Figure 4. 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. What to Do If Your Orthopaedic Surgery Is Postponed. This part of the tibia is also known as the tibial plateau.

This puts tension on a torn meniscus. The one towards the back of leg is the posterior horn. We have two menisci in either knee. 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 ]. Nonsteroidal anti-inflammatory drugs (NSAIDs), Inability to move your knee through its full range of motion. Several variations in meniscal tear patterns have been granted specific names that recognize the unique characteristics of the tear. The operative equipment needs and post-operative rehabilitation process markedly differ between meniscal repair and partial meniscectomy. Medial meniscal root tears are radial tears within 1 cm of the meniscal root insertion or an avulsion of the insertion of the meniscus. Identification of a meniscal root tear on MRI may be challenging due to the relatively small size of the root. The absolute indication for specialist referral is the locked knee loss of joint function necessitates surgical intervention. The difference in tear type between these populations is explained by the three-dimensional fibrous structure of the meniscus: horizontal delamination occurs in degenerative injuries, while the fibrous structure is ruptured in a vertical fashion in younger patients. It absorbs shock in your knee and keeps it stable. The McMurray test (shown here) will help your doctor determine if you have a meniscus tear. Meniscus tears are either degenerative or acute. 6 1.

A tear can also develop slowly as the meniscus loses resiliency. In addition, focal chondral lesions occur more commonly with medial than lateral-sided injuries. Unfortunately, general practitioners cannot currently order Medicare funded MRI, although this may change with The Royal Australian College of General Practitioners recent submission to the Australian Government Department of Health and Ageing. By the time people reach their twenties or thirties, intrasubstance changes of the meniscus tissue are common. Meniscal tears are common sports-related injuries in young athletes and can also present as a degenerative condition in older patients. Torn meniscus symptoms Symptoms are usually sudden onset, however, can develop gradually over time. At The Orthopedic Clinic, we want you to live your life in full motion. Nonoperative treatments are often successful in patients with certain types of tear patients who have no loss of joint function, suffer minimal pain or swelling and are willing to reduce their activities temporarily or in the long term. Trauma to medial collateral ligament usually also involves medial meniscus. Connect with a U.S. board-certified doctor by text or video anytime, anywhere. Still, many people with a torn meniscus can walk, stand, sit, and sleep without pain. 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.
