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. Metcalf MH, Barrett GR. During the exam, your doctor will look for signs of tenderness along the joint line. Larger, unstable tears of this type often cause mechanical symptoms, however, and therefore warrant operative treatment, usually via partial meniscectomy. ICD 9 Codes: 717.4 derangement of the lateral meniscus 717.3 derangement of the medial meniscus 836.0 lateral meniscus tear 836.1 medial meniscus tear Case Type / Diagnosis: Functional Anatomy: The menisci are semi lunar shaped cartilages on the medial and lateral sides of the knee joint. 12 McGinty JB, Burkhart SS, Jackson RW, et al. However, anyone at any age can tear the meniscus. If the test is positive (suggesting a meniscal tear), the patient will feel pain and the clinician will feel and/or hear meniscal movement when the meniscus is compressed between the tibia and femur 32, Figure 2. 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. Both of them have 2 causes. Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. Surgery is most likely needed to resolve your problem. Pain, especially when twisting or rotating your knee. Fat-suppressed coronal images demonstrate before and after images following repair of a bucket handle tear. True locking is less common, and suggests a bucket-handle tear, with the torn fragment preventing full extension. An awkward twist when getting up from a chair may be enough to cause a tear in an aging meniscus. Skeletal Radiology 2004; 33:260-264. Mri of knee shows "oblique tear posterior horn medial meniscus, lateral patellar plica and minimal synovial knee effusion" will i need surgery? Henning C, Lynch M, Clark J. Vascularity for healing of meniscus repairs. This information is provided as an educational service and is not intended to serve as medical advice. a feeling that your knee is catching or locking, usually when it's bent - you may notice it clicking. The RICE protocol is effective for most sports-related injuries. You might develop the following signs and symptoms in your knee: A popping sensation. Your doctor will bend your knee, then straighten and rotate it. 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 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. Of course, if a displaced meniscal fragment is identified, the tear is by definition unstable. 12 Sources By Jonathan Cluett, MD The medial meniscus is on the innermost side of your knee (the C-shaped curve faces in toward your body, the opposite knee). Disclosures: LaPrade reports he is a consultant for and receives royalties from Arthrex, Ossur and Smith & Nephew. Primary repair of medial meniscal avulsions: 2 case studies. what is the treatment? Now, 49 I have had intense pain 2 days after a 3 hour steep mountain walk- the first in 6 months. 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. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). Radial tears, because they are oriented perpendicular to the c-shaped fibers of the meniscus, have a devastating effect upon meniscal function. The ideal candidate for a medial meniscal root repair is an individual younger than 40 years who presents after an acute, traumatic event with a BMI less than 30 and a MRI that shows a medial meniscal root tear without secondary signs of osteoarthrosis or varus malalignment. Solomon L, Warwick D, Nayagam S. Apley's Concise System of Orthopaedics and Fractures. Missouri: Mosby, 1998. Whats the best way to treat an oblique fracture? With proper diagnosis, treatment, and rehabilitation, patients often return to their pre-injury abilities. This is because this area has rich blood supply and blood cells can regenerate meniscus tissue or help it heal after surgical repair. Most oblique meniscus tears are happen in the posterior third of the medial meniscus. This most often happens when the tear develops over a period of time. Medial meniscal root tears are more frequently diagnosed in patients who are older than 40 years, are overweight and cannot recall an inciting event. 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. Intrasubstance/incomplete tear (top left) This type of tear is often a sign of degenerative changes in the meniscus tissue. American Board of Orthopaedic Surgery Practice of the Orthopaedic Surgeon: Part-II, certification examination case mix. Meniscus tears are extremely common knee injuries. If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically. Harrison BK, Abell BE, Gibson TW. This part of the tibia is also known as the tibial plateau. They include: The Royal Australian College of General Practitioners, 100 Wellington Parade, East Melbourne, Victoria 3002, Australia. 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. The medial meniscus has a firmer capsular attachment than the lateral meniscus. 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. from the American Academy of Orthopaedic Surgeons, Questions and Answers for Patients Regarding Elective Surgery and COVID-19. The medial meniscus is on the inner side of the knee joint. The posterior horn of the medial meniscus is especially likely to develop tears as we get older. Knee Surg Sports Traumatol Arthrosc 2011 Aug 11. 17 Old Kings Road N., Suite K Palm Coast, FL 32137, East Coast Surgery Center 3 Thornton DD, Rubin DA. The meniscus is a thick cartilage structure that sits between the bones of the knee. Knee arthroscopy is one of the most commonly performed surgical procedures. Magnetic resonance imaging (MRI) scans. bucket-handle tear: displaced vertical tear parrot beak tear: oblique radial tear Radiographic features Plain radiograph On plain radiographs, meniscal tears are not visible. Although surgical repair has led to improved patient-reported function, there are conflicting reports on the progression of cartilage degeneration. J Bone J Surg Am 2006;88:6607. https://www.webmd.com/pain-management/knee-pain/meniscus-tear-injury Have swelling, stiffness or tightness in your knee. 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 . Symptomatic treatment with rest, ice, NSAIDs and/or an unloader brace may help alleviate symptoms in some cases. See your ortho for an evaluation. Meniscus tears are either degenerative or acute. These tears occur within the avascular zone of the meniscus where there is no blood supply. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. Full thickness tears are the complete disruption of the fibers of the supraspinatus muscle, and generally require a more aggressive treatment plan and surgery. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. Conservative management of the patient with a meniscal tear. In fact, the tear will most likely get bigger leading to additional damage if not taken care of soon. Aged, worn tissue is more prone to tears. In the present case, a full-thickness radial tear of the medial meniscus is visualized (Fig 1).An arthroscopic torpedo shaver (Arthrex, Naples, FL, U.S.A.) is used to debride the meniscus tear edges back to a healthy, stable rim (Fig 2).For improved access to the medial meniscus, an 18-gauge spinal . Oblique tears commonly cause flaps and flaps are generally not good. Ercin E, Kaya I, Sungur I, Demirbas E, Ugras AA, Cetinus EM. Jul 2000;31(3):419-36. 2013. 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 ]. These are paraphrased. 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. As the risk of osteoarthritis is increased if meniscal structures are not optimally functional,7 it may also be appropriate to refer all young patients for opinion if symptoms do not rapidly improve. 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. If this cartilage tears, the result is pain, stiffness, and swelling. Depending on the severity of the injury, surgical repair may or may not be needed. Bernstein J. 1993;9(1):33-51. Bull NYU Hosp Jt Dis 2010;68:8490. This leads to decreased contact area and increased contact pressure and ultimately results in joint overloading and degenerative changes in the knee similar to a total meniscectomy state. (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. Ask if your condition can be treated in other ways. In sports, a meniscus tear usually happens suddenly. The question about meniscus tears and the subsequent MRI in emails we receive are numerous. The tear results in a vertical signal abnormality on sagittal MR images. meniscal tear / avulsion off tibial plateau CIRCUMFERENTIAL FIBERS basicall equivalent to a total meniscetyomy - try to repair these at all cost!
