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. 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 . These lie on the inside (medial) and outside (lateral) edges of the top of your tibia (shin bone). Because other knee injuries can cause similar symptoms, your doctor may order imaging tests to help confirm the diagnosis. The described meniscal tears will lead to possible necessary total knee replacement. Although the pain improved, the patient could not flex her knee joint deeply. Larger, unstable tears of this type often cause mechanical symptoms, however, and therefore warrant operative treatment, usually via partial meniscectomy. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. HealthTap uses cookies to enhance your site experience and for analytics and advertising purposes. They act as shock absorbers and stabilize the knee. History, clinical findings, magnetic resonance imaging, and arthroscopic correlation in meniscal lesions. 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. 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. Gillquist J, Hamberg P, Lysholm J. Endoscopic partial and total meniscectomy. 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). https://www.verywellhealth.com/types-of-meniscus-tears-3862073 MRI scans show (left) a normal meniscus and (right) a torn meniscus. We have the medial meniscus on the inner side of the knee and the lateral meniscus on the outer side of the knee. Always follow your healthcare professional's instructions. I have a oblique grade 3 tear posterior horn of the medial meniscus. The medial meniscus transmits approximately 50% of the total joint load of the knee medial compartment, thus protecting the articular cartilage from excessive force. Because there is no supply, there is little capacity for these tears to heal on their own. The Thessaly test is the most sensitive and specific clinical test to diagnose meniscal injury. The tear results in a vertical signal abnormality on sagittal MR images. he is 44 y o tennis player. An MRI scan assesses the soft tissues in your knee joint, including the menisci, cartilage, tendons, and ligaments.

We have also seen complete meniscal root avulsions in the cruciate ligament-injured knee with complete injury of the medial ligament and posterior oblique ligament that opens in full extension. X-rays and MRIsallow the doctor to evaluate the bone and soft tissue at the knee. If you continue to use this site we will assume that you are happy with it. As people age, they are more likely to have degenerative meniscus tears. Meniscal tears often occur in young patients who have suffered a twisting injury to the knee. Most oblique meniscus tears are happen in the posterior third of the medial meniscus. The test is positive if symptoms are reproduced on rotation 10. In (17a), the preoperative study, a large displaced "handle" (arrow) from the body of the lateral meniscus is seen near the intercondylar notch. Includes interactive tool to help you decide. X-rays provide images of dense structures, such as bone. 2000-2022 The StayWell Company, LLC. Adjunctive measures to promote vascularity and healing at the repair sites are also recommended. These tears occur within the avascular zone of the meniscus where there is no blood supply. Pain and/or clicking on compression suggest a meniscal lesion 1,32, Figure 3. Coronal MRI sequences are generally considered the best images for visualization of medial meniscal root tears (Figure 1). The meniscus is a C-shaped cartilage disk that is found in the knee. In many areas, nonessential orthopaedic procedures that were postponed due to COVID-19 have resumed. In brief: meniscal tears. The one towards the back of leg is the posterior horn. This piece of soft tissue often becomes torn, especially in athletes, due to quick movements and sudden trauma. Magnetic resonance imaging is first line for investigating potential meniscal lesions, but should not replace thorough clinical history and examination. An MRI is 70 to 90 percent accurate in identifying whether the meniscus has been torn and how badly. Top answers from doctors based on your search: Created for people with ongoing healthcare needs but benefits everyone. For information:Questions and Answers for Patients Regarding Elective Surgery and COVID-19. Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. Similarly, tears that are not associated with locking of the knee will typically become less painful over time. Figure 4. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. If you are having pain, swelling and catching, then the only reasonable option would be arthroscopic knee surgery. The relationships among MM radial/oblique tears, MM extrusion (MME), and the effect of arthroscopic meniscal repair are not established. Solomon L, Warwick D, Nayagam S. Apley's Concise System of Orthopaedics and Fractures. A gradient-echo T2*-weighted sagittal image demonstrates a tear within the posterior horn of the medial meniscus (arrow). Seldom are they the sign of a problem. Trauma to medial collateral ligament usually also involves medial meniscus. Jarit G, Bosco J. Meniscal repair and reconstruction. Surgery is most likely needed to resolve your problem. 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). 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. 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. How to treat an oblique tear of the posterior horn of the medial meniscus? The majority of these types of tears do not need surgery. The operative equipment needs and post-operative rehabilitation process markedly differ between meniscal repair and partial meniscectomy. Nicholas Colyvas, MDClinical ProfessorDepartment of Orthopaedic Surgeryorthosurg.ucsf.edu J Bone Joint Surg Am 2005;87:71524. The vascularity of the peripheral menisci is primarily derived from the Most likely, your doctor will recommend that you rest, use pain relievers, and. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. 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. Am J Sports Med 2008;36:12839. Meniscal tears are the most common lesions followed by the meniscal cyst. The medial meniscus is an important secondary stabilizer of the knee. The amount of pain and first appearance of swelling can give important clues about where and how bad the injury is. AJR 2001; 176:771-776. Reactive synovitis and edema (arrowheads) are readily apparent deep to the tibial collateral ligament on the coronal view. These imaging pearls improve recognition of meniscal root tears (Figure 2). Of note, drilling tibial tunnels may improve healing of the meniscus-bone interface due to the presence of progenitor cells and growth factors derived from the bone marrow. In this short surgical video, a degenerative meniscus tear is smoothed down with a motorized shaver during a partial meniscectomy. Pain is typically medial and activity-related (e.g. See your ortho for an evaluation. Call us at(386) 255-4596to schedule an appointment. Meniscus Repair. X-rays. Strengthening exercises will gradually be added to your rehabilitation plan. 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.

Know what to expect if you do not take the medicine or have the test or procedure. Meniscal injury and repair: clinical status. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. (10a) A GRE T2*-weighted sagittal image reveals a complex tear of the posterior horn of the medial meniscus, having horizontal (arrows) and longitudinal (arrowhead) components. True locking is less common, and suggests a bucket-handle tear, with the torn fragment preventing full extension. Historically, medial meniscal root tears have been treated conservatively or by partial meniscectomy. All material on this website is protected by copyright. Know why a test or procedure is recommended and what the results could mean. Clinical results of meniscus repair in patients 40 years and older. Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, .

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. This often causes the knee to become stuck due to a portion of the meniscus blocking the knees normal motion. Incisions were made in the dorsal root of the oblique popliteal ligament and the joint capsule . Usually you will be able to leave the hospital the same day.

In this case, a portion may break off, leaving frayed edges. 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. Radiology 2000; 217:193-200. We believe that by repairing these tears, the degenerative process may be delayed or halted (Figure 6). Common tears include bucket handle, flap, and radial.

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. Note: the cartilage deficit more anteriorly on the medial femoral condyle and altered subchondral cortical bone interface, Figure 5. (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. Description of Medial Meniscus Tear The medial meniscus is an important shock absorber on the inside (medial) aspect of the knee joint. Reciprocally, an increased force is also placed on an ACL graft with a deficient medial meniscus. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. Know how you can contact your provider if you have questions. 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.

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. In this case, a portion may break off, leaving frayed edges. Surgical treatment is usually reserved for younger patients with a vertical longitudinal tear within the vascularised outer third of the meniscus. . Skeletal Radiol 2007;36:14551. 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.

The typical meniscal pain profile comprises well localised joint-line pain (with medial pain generally being indicative of a medial tear and vice-versa). Locking presents in two ways. It has the shape of two C's. The medial meniscus is the C shape on the knee's inner side, and the lateral meniscus is the C shape on the outer side of the knee. Successful outcome and patient satisfaction after medial meniscal root repair are established initially upon appropriate diagnosis and patient selection. 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.
