Many tears are repaired with dartlike devices that are inserted and placed across the tear to hold it together. Acta Orthop Scand 1982;53:9759. Long ago, the menisci were felt to be vestigial structures that served no useful purpose in humans.1 Of course, we now realize that the menisci are vital structures that play a key role in the normal biomechanical function of the knee. AJSM 2003; 31:216-220.

The meniscus is a piece of rubber-like cartilage in the knee situated within the femur and tibia, or thigh bone and shin bone. This presents with a combination of tear patterns. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. The younger population, particularly males with knee instability, is most commonly affected by this type of tear [56]. Vincken PW, ter Braak AP, van Erkel AR, et al. The meniscus is broken down into the outer, middle, and inner thirds. Liodakis E, Hankemeier S, Jagodzinski M, Meller R, Krettek C, Brand J.

Seldom are they the sign of a problem. Ask if your condition can be treated in other ways. Recovery and rehabilitation take a few weeks. 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. The menisci act as cushions between your shin bone (tibia) and your thigh bone (femur). The knee meniscus: structure-function, pathophysiology, current repair techniques, and prospects for regeneration. Anatomy of Knee Joint in a Nutshell - DMA Edu The second patient reviewed in this video is an 11-year-old girl who fell while playing tag and hit the front of her left lower leg. The meniscus can tear from acute trauma or as the result of degenerative changes that happen over time. Because there is no supply, there is little capacity for these tears to heal on their own. Symptoms of a meniscus tear. Depending on the cut thickness, axial MRI images may display the root tear (Figure 3). Knee Surg Sports Traumatol Arthrosc 2010;18:5359. Radiology 2000; 217:193-200. Great Britain: Hodder Arnold, 2005. 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. A loose piece of cartilage can get stuck in the joint, causing the knee to temporarily lock, preventing full extension of the leg. By using our website, you consent to our use of cookies. 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. Seldom are they the sign of a problem. 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.

Barrett GR, Field MH, Treacy SH, Ruff CG. 3rd edn. (5a) A longitudinal tear of the posterior horn of the medial meniscus is illustrated. Identification of a meniscal root tear on MRI may be challenging due to the relatively small size of the root. A meniscus tear can lead to knee instability, an inability to move the knee normally, and chronic knee pain. Location -A tear may be located in the anterior horn, body, or posterior horn.A posterior horn tear is the most common. The tear can be seen as a white line through the dark body of the meniscus. Tears are typically vertical in young patients and horizontal in the elderly (Figure 5). 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). If your MRI indicates a Grade 1 or 2 tear, but your symptoms and physical exam are inconsistent with a tear, surgery may not be needed.

Most oblique meniscus tears are happen in the posterior third of the medial meniscus. A recent study demonstrated 46% of patients with degenerative meniscal tears elected not to have surgery after 4 weeks of nonoperative treatment, and their functional improvement matched patients in the operative group.21 Another study of degenerative tears demonstrated that supervised exercise caused the same reduction in knee pain and the same increase in function and satisfaction as partial meniscectomy plus exercise.23 As degenerative tears are more common in elderly patients, this group is more likely to respond to conservative treatment. With meniscal repair, weight bearing may be severely limited for up to six weeks following surgery, and protection from heavy stress to the knee extends for up to six months. Medial meniscal root tears: Fix it or leave it alone - Healio Our preferred repair method utilizes a two-tunnel transtibial pull-out technique. Your doctor will bend your knee, then straighten and rotate it. In this case, a portion may break off, leaving frayed edges. Conservative management is important in all patients with acute rest, intensive rehabilitation with physiotherapy and modification of activity. Referral is also indicated if the diagnosis is uncertain for review and to access MRI. In many areas, nonessential orthopaedic procedures that were postponed due to COVID-19 have resumed. This type of tear is particularly devastating to meniscal function. Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, . Sometimes, its possible to repair a torn meniscus, especially if you are a young adult. Another exam finding is palpating the anteromedial joint line, while placing a varus stress on a fully extended knee and feeling for meniscal extrusion. 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.

Most people can still walk on their injured knee, and many athletes are able to keep playing with a tear. See your ortho for an evaluation. 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 comparison , however, meniscal root tears (MRTs) often go unnoticed and represent a unique injury pattern with unique biomechanical consequences. https://www.verywellhealth.com/types-of-meniscus-tears-3862073 A lateral meniscus tear (torn meniscus) is a tear of the semicircular fibrous cartilage discs in the knee.

Torn meniscus symptoms Symptoms are usually sudden onset, however, can develop gradually over time. Meniscus surgery is a common operation to remove or repair a torn meniscus, a piece of cartilage in the knee. 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.

Verdonk PC, Demurie A, Almqvist KF, Veys EM, Verbruggen G, Verdonk R. Transplantation of viable meniscal allograft. PDF Meniscal Ramp Lesions 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. The medial meniscus is on the innermost side of your knee (the C-shaped curve faces in toward your body, the opposite knee). 2023 ICD-10-CM Diagnosis Code M23.322 - ICD10Data.com The healing of an Oblique Fracture can take a minimum of four to six weeks to completely heal.
