The menisci are two rubbery disks that help cushion the knee joint. We believe that by repairing these tears, the degenerative process may be delayed or halted (Figure 6). Magnetic resonance imaging as a tool to predict reparability of longitudinal full-thickness meniscus lesions. Extrusion of the medial meniscus (MM) is associated with knee joint pain in osteoarthritic knees. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). Those with a meniscus tear are also more likely to develop osteoarthritis in the injured knee. Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, . 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..

The meniscus is a thick cartilage structure that sits between the bones of the knee. Parrot Beak Tear: MRI It is caused by direct impact in contact sports or twisting. Even better would be to describe a peripheral longitudinal tear extending to the tibial surface within the posterior horn of the medial meniscus! These tears occur within the avascular zone of the meniscus where there is no blood supply. Meniscal tears may be categorized into five common configurations, including horizontal, longitudinal, radial, oblique (parrot-beak), and complex. Severe pain and swelling may occur up to 24 hours afterward. Semin Roentgenol. Torn Cartilage Meniscus - Symptoms, Causes, Treatment & Rehabilitation Meniscal injury and repair: clinical status.

Additionally, the large radial tear dramatically undermines the ability of the meniscus to distribute hoop stress. (Right) Degenerative tear. Rehabilitation of the knee following sports injury. 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. 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. and oblique tear . 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. Question options: . 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. Performing activities that involve aggressive pivoting and twisting of the knee puts you at a significantly higher risk of tearing your meniscus. It seems that in the above knee, the biology of the medial compartment has gone off the ski slope in a degenerative fashion and reversing that ski slope fall seems to be unproven at this time, particularly in the patient with low functional demands, who is older than 40 years and who has a BMI greater than 30. 2010. The healing of an Oblique Fracture can take a minimum of four to six weeks to completely heal. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. How can I tell if I have an oblique fracture?

Meniscal repair and reconstruction. Although some reports have described successful repair of the avascular portion of the meniscus,11 it is generally accepted that meniscal repair is more likely to be successful if it involves or at least communicates with the meniscal red zone, lying within three to four millimeters of the capsular rim.12 A basic principle of meniscal repair is to rasp the tear edges and the parameniscal synovium above and below the meniscus, which is thought to enhance the vascular healing process. Oblique tears give rise to flaps which are mechanical unstable and associated with mechanical symptoms. AJSM 1999; 27:242-250. One of the main tests for meniscus tears is the McMurray test. In cases where surgery is required, this time frame increases to somewhere around three to four months. 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. Grades 1 and 2 are not considered serious. RICE stands for Rest, Ice, Compression, and Elevation. Radiology 2007;242:8593. Arthroscopic repair An arthroscope is inserted into the knee to see the tear. (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. Reciprocally, an increased force is also placed on an ACL graft with a deficient medial meniscus. Because a torn meniscus is made of cartilage, it won't show up on X-rays. Normal knee anatomy. 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. The medial meniscus transmits approximately 50% of the total joint load of the knee medial compartment, thus protecting the articular cartilage from excessive force.

It is estimated that only 10% of the injuries involving the tear of posterior horn medial meniscus are repairable. Surgical treatment is usually reserved for younger patients with a vertical longitudinal tear within the vascularised outer third of the meniscus. New surgical advances allow surgeons to repair these tears. 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). Coronal proton weighted MRI of horizontal tear of lateral meniscus (white arrow) with complicating ganglion (black arrow) at the lateral margin of the meniscus, Australian Family Physician was the peer-reviewed, scholarly journal of The Royal Australian College of General Practitioners (RACGP) from 1971 to 2017. Figure 1. The parrot beak shape of an oblique tear (arrow) is readily apparent on (7a) a proton density-weighted axial image of the menisci. Deep leg presses and squats greater than 70 of knee flexion should be avoided for at least 4 months after surgery.

When people talk about torn cartilage in the knee, they are usually referring to a torn meniscus. These lie on the inside (medial) and outside (lateral) edges of the top of your tibia (shin bone). Meniscal tear configurations: categorization with MR imaging. Bull NYU Hosp Jt Dis 2010;68:8490. Imaging tests X-rays. 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. Herrlin S, Hallander M, Wange P, Weidenhielm L, Werner S. Arthroscopic or conservative treatment of degenerative medial meniscal tears: a prospective randomised trial. There will also be skin discoloration and visible deformity at the site of the injury. The menisci help to transmit weight from one bone to another and play an important role in knee stability. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. Each knee has two C-shaped pieces of cartilage known as menisci. 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). A barely noticeable tear may resurface years later, triggered by something as simple as tripping over a sidewalk curb. what is the treatment? For these, please consult a doctor (virtually or in person). Although the . Knowing where and how a meniscus was torn helps the doctor determine the best treatment..

In addition to categorizing meniscal tears based on morphology, care should be taken to describe the exact location of meniscal tears. (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. Figure 4. Peripheral meniscal tears are among the most common causes of meniscal pathology, particularly occurring in conjunction with anterior cruciate ligament (ACL) injury or deficiency. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. A tear in this "red" zone may heal on its own, or can often be repaired with surgery. Not the symmetrical shape of the lateral meniscus (red outline) and the asymmetry of the medial meniscus (blue outline), where the posterior horn (asterisk) is significantly larger than the anterior horn.

Arthroscopic Repair of the Medial Meniscus Radial/Oblique Tear Prevents The ghost sign or absence of an identifiable meniscus anterior to the posterior cruciate ligament is also indicative of a root tear (Figure 2). 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. Without nutrients from blood, tears in this "white" zone with limited blood flow cannot heal. The MRI revealed a vertical flap (oblique) tear of the medial meniscus.
