Meniscal Root Tears: Current Concepts Revie

  1. Meniscal root tears are defined as bony or soft tissue root avulsion injuries or radial tears within 1 cm of meniscus root attachment (1-4). These tears are increasingly being recognized as a cause of morbidity, development of early osteoarthritis (OA), and altered joint kinematics when not surgically repaired (3, 5-9)
  2. Meniscal roots in the knee refer to parts of the menisci which are critical attachment sites of the medial and lateral menisci to the central tibial plateau. There are anterior and posterior roots for each meniscus
  3. PHMM 16.5 mm posterior and 7.7 mm medial to the center of the posterior medial meniscal root attachment. The meniscotibial ligament tibial attachment was 5.9 6 1.3 mm inferior to the articular cartilage margin of the posterior medial tibial plateau
  4. ence (MTE). The anterior medial root inserts 18.2 mm anteromedial to the tibial ACL attachment, and 4 mm posterior to the anterior rim of the medial tibial plateau. The mean total area of the footprint is 110.4 mm 2. [ 27
  5. In meniscal root tears (MRTs), the disruption of collagen fibers that provide hoop strength results in extrusion of the menisci, altering their biomechanical properties. Anatomy. The main functions of menisci are absorption and transmission of the loads increasing the congruity between the femoral condyles and the tibial upper surface

Meniscal root tears are an increasingly recognized injury leading to notable functional limitations, potential rapid cartilage deterioration of the affected compartment, and subsequent risk of total knee arthroplasty if left untreated. Repair of these tears is advised when articular cartilage remain The medial meniscal posterior root is the least mobile of the meniscal roots and provides stability to the knee against external rotation and lateral translation of the tibia. (d-f) Axial (d), coronal (e), and sagittal (f) proton-density-weighted MR images of the lateral meniscal posterior root attachment (arrow) show the root attaching posteromedially to the lateral tibial tubercle anterior to the posterior cruciate ligament and posterior to the anterior cruciate ligament Gross anatomy. The meniscotibial ligaments attach the menisci to the tibial condyles at various locations apart from the meniscal root attachments 1-4.. Attachments Medial meniscus. The medial meniscus is attached to the medial tibial condyle at the following locations 1-3:. posterior horn via the posterior meniscotibial ligament 1; midportion or corpus via the meniscotibial portion of the. There are two types of cartilage in the knee; articular cartilage and meniscus cartilage. Articular cartilage is made up of collagen, proteoglycans and water which lines the end of the bones that meet to form a joint. The primary function of the articular cartilage is to provide a smooth gliding surface for joint motion. Rubbing articular cartilage on articular cartilage is approximately 5 times more smooth, or with less friction, than rubbing ice on ice

The integrity of the meniscal root insertions is fundamental to preserve correct knee kinematics and avoid degenerative changes of the knee. Injuries to the meniscal attachments can lead to meniscal extrusion, decreased contact surface, increased cartilage stress, and ultimately articular degeneration be distinguished in regard to the meniscus attachments anatomy: zone 1 (of the anterior root), zone 2 (anterome-dial zone), zone 3 (the medial zone), zone 4 (the posterior zone) and the zone 5 (of the posterior root). The under-standing of the meniscal anatomy is especially crucial for meniscus repair but also for correct fixation of the anterio Description of Meniscal Root Tears Both the medial and lateral menisci have a stout attachment at their very posterior aspects, which are called the root attachments. These root attachments are important because they hold the meniscus in place, provides stability to the circumferential hoop fibers of the meniscus, and prevents meniscal extrusion 40 Meniscal root repairs are gaining recognition as a consequential treatment for improving patient outcomes. 3 28 Thus far, research on meniscal roots has focused primarily on anatomy (FIGURE 1), biomechanics, and surgical techniques. Download Figure Download PowerPoint FIGURE 1 Meniscal roots are defined as the insertion of the meniscal horns into the tibial plateau, and extend to a distance of 0.9 mm from the attachment site. 20 Respecting some characteristics, the roots of the meniscus are basically formed by a dense fiber core, surrounded by additional fibers. 1, 21, 22 Histologically, meniscal roots have a structure similar to a typical enthesis, comprised of four zones: meniscus fibers, non-calcified fibrocartilage, fibrocartilage, and calcified bone.2

Meniscal root tear A meniscal root tear is a radial tear located at the meniscal root. Normally when you image the posterior cruciate ligament on sagittal images you should see a considerable portion of the posterior horn of the meniscus on that image or the image adjacent to it The anterior lateral meniscal root ligament attaches the anterior horn of the lateral meniscus to the lateral intercondylar tibial eminence just behind the anterior cruciate ligament (ACL) insertion (Figs. 5.11 and 5.12) [ 1 ]

Anatomy of the meniscal roots. Axial view of the tibial plateau demonstrating the anatomic relationship of the meniscal roots and the cruciate ligaments
  2. Meniscal gross anatomy. (A) The medial meniscus is typically more crescent-shaped, with the width increasing as one moves from anterior to posterior. The lateral meniscus is typically more C-shaped with a relatively constant width
  3. Anatomy of the Meniscal Roots Generally, the medial meniscal root attachments are greater in area than those of the lateral meniscus, with the anterior horn of the medial meniscus being the largest and strongest footprint of all
  4. The meniscal roots and supporting structures anchor the menisci to the tibial plateau and resist hoop stress, thereby preventing radial displacement of the menisci and secondary degenerative tibiofemoral compartment changes that may occur if this is compromised
  5. Meniscal Anatomy: Biomechanics • When the Peripheral Margin of the meniscus and Root attachments are intact Normal Hoop Stress increases contact area, decreases contact pressures, and protects the knee: -Lateral Meniscus decreases compartment loads by 70% -Medial Meniscus decreases compartment loads by 50% • Walker et al., CORR 197
  6. Anatomy Three bones meet to form your knee joint: your thighbone (femur), shinbone (tibia), and kneecap (patella). Two wedge-shaped pieces of fibrocartilage act as shock absorbers between your thighbone and shinbone. These are the menisci
  7. There is a close association between meniscal extrusion and root tears. Specifically, 76% of medial root tears have extrusion, and 39% of extrusions have medial root tears . However, meniscal extrusion can also be seen with complex tears, large radial tears, and severe meniscal degeneration . Figure 20a Indirect signs of meniscal tear

Meniscal root tears: Solving the silent epidemi

The meniscal roots represent the attachment sites of the menisci to the medial tibial eminence. The posterior meniscal root of the medial meniscus attaches immediately anterior to the posterior cruciate ligament (PCL). The posterior meniscus should be seen on every sagittal image up to the one that shows the PCL (figure 3a) Defining the quantitative anatomy of the anterior meniscal root attachments is essential for developing improved diagnostic and surgical techniques. Hypothesis: The anterior medial (AM) and anterior lateral (AL) meniscal roots could be quantitatively defined relative to open and arthroscopic surgical landmarks Meniscal root tears part II - the road to recovery. by Chris Mallac in Other.

The anterior and posterior horns are firmly attached to bone through the insertional ligaments known as the meniscal root ligaments. The tibial attachment of the anterior horn of the medial meniscus or the anterior medial root ligament is situated at the intercondylar fossa, 6-7 mm anteriorly to the anterior cruciate ligament (ACL) attachment (Fig. 5.4) [] treatment methods. Currently, repair of meniscal root injuries is the treatment of choice with the aim of restor-ing joint kinematics, contact pressures, and delaying the development of OA [15, 16]. This review will focus mainly on posterior meniscal root tears including the anatomy, biomechanics, clinical evaluation, treatment methods Meniscal root anatomy is also complex; consisting of the ligamentous mid-substance (root ligament), the transition zone between the meniscal body and root ligament; the relationship between suture location and maximum failure load has not been investigated in a simulated surgical repair Meniscal root tears, less common than meniscal body tears and frequently unrecognized, are a subset of meniscal injuries that often result in significant knee joint disorders.

Meniscal root tears: from basic science to ultimate

The meniscus has 3 main zones, the 1) posterior horn, the 2) body, and the 3) anterior horn. Each horn is anchored to the bone at the meniscus root (anterior and posterior). When you put weight on your leg, it is the meniscal roots that transfer the axial loading forces of the knee into hoop stress in the meniscus This paper focuses on the anatomical attachment of the medial meniscus. Detailed anatomical dissections have been performed and illustrated. Five zones can be distinguished in regard to the meniscus attachments anatomy: zone 1 (of the anterior root), zone 2 (anteromedial zone), zone 3 (the medial zone), zone 4 (the posterior zone) and the zone 5 (of the posterior root)

[Medline] Understanding of the gross anatomy, microvascular anatomy, and meniscofemoral attachments of the meniscus is vital to understanding treatment of meniscal injuries. The meniscus is a dense extracellular matrix comprising water and collagen, with interspersed cells, glycoproteins, and proteoglycans also contributing to its unique viscoelastic. The anterior horn lateral meniscus/ anterior lateral meniscal root can have a 'speckled or spotty appearance in up to 60% of patients, which is likely secondary to the adjacent/crossing fibers of the anterior cruciate ligament insertion. 6 This 'speckled appearance can mimic a tear of the anterior horn lateral meniscus (13a). 13

There is a root attachment in the front of the meniscus and a root attachment in the back (posterior) of the meniscus. In most injuries, it is the posterior root attachment that is torn. Problems arise with root tears because if the root of the meniscus is torn, then the entire meniscus becomes non-functional A meniscus root tear occurs when one or both of these roots tear away from the bone. Most meniscus root tears occur very close to the root near the meniscus itself and are called radial root tears. This specific type of tear makes up 90% of all meniscal root tears The meniscal root is a small portion of the meniscus that attaches and anchors the anterior and posterior horns of the meniscus to the intercondylar fossa or eminence of the tibia. Its usually the posterior root of the meniscus that is torn and medial more than lateral meniscus Currently, the anatomical study of the meniscal roots mainly included cadaveric study, arthroscopy, and MRI. [1,11,12,14-16] Some meniscal roots, such as the PRLM, had been difficult to visualize fully both on the cadaveric knee specimens and by arthroscopy, because of their unique configuration and position.

Medial Meniscus Anatomy. The medial Meniscus of the knee is a C-shaped structure larger in radius than the lateral meniscus. Posterior horn is wider than the anterior horn. Most of the weight is borne on the posterior portion of the meniscus. The peripheral attachments are more rigid than the lateral meniscus The meniscus is a c-shaped cartilage disc that sits inside your knee joint between your thigh bone (femur) and your shin bone (tibia). There are two meniscii in the knee, the medial and lateral.

Meniscal root tears are often associated with extrusion of the meniscus beyond the margin of the tibial plateau. More than 3 mm meniscus extrusion is often associated with tears involving the meniscal root (6). In the case on the left there is a complete radial tear separating the posterior horn from its root (red arrows) The medial meniscus is most commonly torn as it is less mobile (moves less) than the lateral meniscus. Meniscal tears can occur with trauma or overuse. In the younger patient, it usually occurs after a forceful twisting injury on a planted foot that may occur to the knee while playing sports- particularly ones that require a lot of pivoting.

A meniscus is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. In humans they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; in other animals they may be present in other joints..

Meniscal Root Tear Repair: Why, When and How

  1. MRI of the Knee Normal Meniscal and Cartilage Anatomy. Douglas Gregerson, DC, DACBR. The knee is a body part that is frequently studied with MRI. Meniscal tears are a fairly frequent occurrence in the knee. It is essential to have a good knowledge of the normal appearance of the cartilage and menisci with MRI before beginning to assess possible.
  2. Torn meniscus. The meniscus is a C-shaped piece of tough, rubbery cartilage that acts as a shock absorber between your shinbone and thighbone. It can be torn if you suddenly twist your knee while bearing weight on it. A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee.
  3. Posterior horn medial meniscus tears in children tend to lead to a recommendation to consider surgery since these tears are usually repairable. In addition, children have much more regenerative or healing potential. If a meniscus tear is repaired (sutured back together), then the risk of developing arthritis later in life drops significantly
  4. ANATOMY OF THE MENISCI AND MENISCAL ROOTS. The menisci in the knee are two semi-lunar discs made of fibrocartilage. The major components of the meniscus are water, collagen and proteoglycans. They are located between the distal femur and the proximal tibia in the medial and lateral compartments of the knee. The normal meniscus is wedge-shaped.
  5. Background: Although there have been some attempts to reveal the anatomy of the posterior root of the lateral meniscus (PRLM) through cadaver studies, arthroscopy, or imaging, it has not yet been described fully
  6. Medial posterior root tears are the focus of most of the papers I read. One study found that up to 21.5% of medial meniscus tears involved the posterior root. LaPrade et al have developed a classification of these tears. Type 2 is most common. Figure 1. From LaPrade CM et al. Meniscal Root Tears. Am J Sports Med. 2015;43(2):363-9

Illustrated anatomy of the knee meniscus. The meniscus from the side The meniscus is a wedge-shaped cartilagenous shock-absorber, which exists between femur and tibia on either side of the joint.Each knee has two menisci.. In the illustration you can see the two menisci between the femur and the tibia bones Meniscus root is defined as attachment of meniscus horn in to the tibial plateau. About 70% of load transmitted through the knee is supported by medial and lateral menisci, they aid in uniform weight distribution and reduce contact pressures. Meniscus root act as an anchor for menicus tissue and resist the tendency for meniscus extrusion Meniscus tears that are cut out through debridement have a much shorter recovery time than those that are repaired with stitches. Patients use crutches for 1-2 days, and are able to return to their everyday activities within one week. At one month the average patient is 80% back to their pre-tear activities and sports, and 90-95% at two months Pathophysiology. Meniscal root tears are defined either as an avulsion of the insertion of the meniscus attachment or complete radial tears that are located within 1 cm of the meniscus insertion.10 20 Meniscal root tears have been previously classified into five types21: (1) partial root tear, (2) complete radial root tear, (3) complete root tear with a bucket handle meniscus tear, (4) oblique.
