Survivorship analysis and clinical outcome of one hundred cases. During weight-bearing activities, the menisci dissipate axial loads and contain hoop stresses. Rehabilitation time for a meniscus repair is about 3 to 6 months. The procedure begins with a complete diagnostic arthroscopy using a 30-degree arthroscope. If you have a meniscus tear, this movement may cause pain, clicking, or a clunking sensation within the joint. 8 Ruff C, Weingardt J, Russ P, Kilcoyne R. MR imaging patterns of displaced meniscus injuries of the knee. 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. Scholten RJ, Deville WL, Opstelten W, Bijl D, van der Plas CG, Bouter LM. w/severe pain? Arthroscopic repair An arthroscope is inserted into the knee to see the tear. This "C" shaped cartilage helps disperse impact and displace force exerted upon the knee while walking, running, and other mild to high-energy and impact motions. You might develop the following signs and symptoms in your knee: A popping sensation. Explains when surgery is done. Radial Tear B. Horizontal Tear C. Vertical Tear D. Longitudinal Tear E. Oblique Tear. Extrusion of the medial meniscus (MM) is associated with knee joint pain in osteoarthritic knees. Meniscus tears can vary widely in size and severity. Ask if your condition can be treated in other ways. Symptoms. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. 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. 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. Operative Arthroscopy, 3rd Edition, 2002, Lippincott Williams and Wilkins. The medial meniscus is an important secondary stabilizer of the knee. The clinician applies axial pressure to the foot and rotates the tibia internally and externally. However, it may also occur in older athletes through gradual degeneration. Arthroscopic repair of meniscal tears extending into the avascular zone in patients younger than twenty years of age.

Also write down any new instructions your provider gives you. OKeefe R, et al. Incisions were made in the dorsal root of the oblique popliteal ligament and the joint capsule . 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. The medial meniscus is the cushion that is located on the inside part of the knee. Garrett WE Jr, Swiontkowski MF, Weinstein JN, et al. All material on this website is protected by copyright.

If the tear is associated with arthritis it will typically improve over time as the arthritis is treated. All Rights Reserved. The menisci of the knee have several important roles: The medial meniscus is 'C' shaped whereas the lateral is a shorter incomplete circle with closer spaced 'horns'. 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. I have a oblique grade 3 tear posterior horn of the medial meniscus. J Fam Pract 2001;50:93844. Rehabilitation of the knee following sports injury. Am J Sports Med 2008;36:12839. 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. Oblique tears commonly cause flaps and flaps are generally not good. summary. Radial tears, because they are oriented perpendicular to the c-shaped fibers of the meniscus, have a devastating effect upon meniscal function. X-rays and MRIsallow the doctor to evaluate the bone and soft tissue at the knee. Clinical outcomes following isolated lateral meniscal allograft transplantation. The amount of pain and first appearance of swelling can give important clues about where and how bad the injury is. Sources: The accuracy of physical diagnostic tests for assessing meniscal lesions of the knee: a meta-analysis. 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. AJSM 2002; 30:589-600. Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites. Patients are often aware of movements that aggravate mensical pain, but should also be educated to avoid twisting on a weight bearing, flexed knee. Primary repair of medial meniscal avulsions: 2 case studies. What is Meniscus Radial Tear. (386) 254-6819, Main Office & Walk-In Clinic 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. Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, . 1871 LPGA Blvd., Daytona Beach, FL 32117. Meniscus tears, indicated by MRI, are classified in three grades. 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. With regard to tear morphology, the classic ideal candidate for meniscal repair is the peripheral longitudinal tear. 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 . There may be some pain. J Bone Joint Surg Am 2005;87:71524. In brief: meniscal tears. what is the best possible treatment? Sometimes, its possible to repair a torn meniscus, especially if you are a young adult. No meniscal tears were observed. Verdonk PC, Demurie A, Almqvist KF, Veys EM, Verbruggen G, Verdonk R. Transplantation of viable meniscal allograft. Meniscal injury and repair: clinical status. 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. oblique ligament, and the . (16a) Sagittal and (16b) axial proton density weighted images reveal a very large radial tear (arrows) that extends broadly across the entire width of the anterior body of the lateral meniscus. How can I tell if I have an oblique fracture? (Right) Degenerative tear. With advances in surgical techniques and instrumentation, meniscal root repair is a viable option that can restore the biomechanics and kinematics of the knee (Figure 4). 5 Jee WH, McCauley TR, Kim JM, et al. One of the most common knee injuries is a torn meniscus. 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). 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. 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. Arthroscopy. Br Med Bull 2007;84:523. 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. Question options: . 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. The vascularity of the peripheral menisci is primarily derived from the Recovery and rehabilitation take a few weeks. 1165 Dunlawton Ave., Suite 102 Port Orange, FL 32127, Port Orange East & Walk-In Clinic Because the pieces cannot grow back together, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically. 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. 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). Successful outcome and patient satisfaction after medial meniscal root repair are established initially upon appropriate diagnosis and patient selection. Steroid injection. 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. Torn meniscus symptoms Symptoms are usually sudden onset, however, can develop gradually over time. When small, conservative therapy or simply rasping the meniscus may result in healing of these tear types. The McMurray test (shown here) will help your doctor determine if you have a meniscus tear. 16 OShea JJ, Shelbourne KD. Arthroscopy 2006;22:77180. Oblique tears give rise to flaps which are mechanical unstable and associated with mechanical symptoms. Semin Roentgenol. From January 2018, it was superseded by AJGP: Australian Journal of General Practice, The Royal Australian College of General Practitioners 2021. Fat-suppressed coronal images demonstrate before and after images following repair of a bucket handle tear. In this case, a portion may break off, leaving frayed edges. Your doctor will bend your knee, then straighten and rotate it. 1 Sutton JB. These are the menisci. The absolute indication for specialist referral is the locked knee loss of joint function necessitates surgical intervention. Additionally, the large radial tear dramatically undermines the ability of the meniscus to distribute hoop stress. All rights reserved. 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 . Meniscal repair surgeries do the best when the meniscal tear extends into the middle 50% of meniscal substance. This provides a clear view of the inside of the knee. If you have a meniscus tear, this movement may cause pain, clicking, or a clunking sensation within the joint. Of course, if a displaced meniscal fragment is identified, the tear is by definition unstable. Common tears include bucket handle, flap, and radial. In this short surgical video, a degenerative meniscus tear is smoothed down with a motorized shaver during a partial meniscectomy. This puts tension on a torn meniscus. The device is small and contains a light and a camera, which transmits images from inside the knee onto a monitor. Sagittal peripheral meniscal images demonstrate the normal anatomical 'bow-tie configuration' (the central meniscal body with the anterior and posterior horns as well circumscribed triangles. Similarly, tears that are not associated with locking of the knee will typically become less painful over time. Oblique tears combine features of radial and longitudinal tears in that they lie perpendicular to the free edge of the meniscus but then curve such that a portion of it lies parallel to the c-shaped fibers of the meniscus. 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. Orthopedics 2009;32:8. A prospective study of the nonoperative treatment of degenerative meniscus tears. Progressive weight-bearing begins at 6 weeks, with full weight-bearing at 8 weeks. It is important to describe your symptoms accurately. In case of an open or unstable fracture, the bone may protrude out of the skin surface and be exposed to environmental contaminants. Those with a meniscus tear are also more likely to develop osteoarthritis in the injured knee. This is termed the 'red-red zone' (denoting area of vascularity).2,4 repair of the 'red-white zone' (watershed area between vascular and avascular meniscus) is controversial25 with many different surgical techniques.26 tears in the 'white-white zone' (avascular zone) are rarely repaired rather the damaged segment is resected (meniscectomy). Many tears are repaired with dartlike devices that are inserted and placed across the tear to hold it together. Pathology - a tear that has developed gradually in the meniscus. 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. Meniscal tears may be categorized into five common configurations, including horizontal, longitudinal, radial, oblique (parrot-beak), and complex.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). This often causes the knee to become stuck due to a portion of the meniscus blocking the knees normal motion. 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. It is estimated that only 10% of the injuries involving the tear of posterior horn medial meniscus are repairable. 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. Fax This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. How is Oblique Fracture Treated? Helms CA, Laorr A, Cannon WD, Jr. Know what to expect if you do not take the medicine or have the test or procedure.
