When appropriate, tears that appear to involve the periphery, or red zone of the meniscus, should be described as such (9a), thereby alerting the surgeon to the fact that the tear is more amenable to repair. Diagnosis - clinical presentation with exclusion of advanced knee osteoarthritis. Weakness, grinding, instability or giving way rarely result from meniscal pathology. Although an X-ray will not show a meniscus tear, your doctor may order one to look for other causes of knee pain, such as osteoarthritis. Meniscal intra-substance signal abnormalities are defined as an increased signal that does not fulfill the criteria for a meniscal tear according the "two-slice-touch" rule (i.e., it does not reach the meniscal surface on two consecutive views) and is a common finding on routine MRI of the knee (Fig. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Tears should be characterized with regard to morphology, size, location, and stability, all of which are important factors that may influence the choice of operative treatment.

The difference in tear type between these populations is explained by the three-dimensional fibrous structure of the meniscus: horizontal delamination occurs in degenerative injuries, while the fibrous structure is ruptured in a vertical fashion in younger patients. Meniscus Surgery. Meniscal tears often occur in young patients who have suffered a twisting injury to the knee.

A high level of suspicion is required to detect these injuries, and repair is recommended to preserve joint function. Sources: The ghost sign or absence of an identifiable meniscus anterior to the posterior cruciate ligament is also indicative of a root tear (Figure 2). Peripheral meniscal tears are among the most common causes of meniscal pathology, particularly occurring in conjunction with anterior cruciate ligament (ACL) injury or deficiency. These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses. Additional pain may be felt when flexing or twisting the knee.

The meniscus can tear from acute trauma or as the result of degenerative changes that happen over time. Conservative management of the patient with a meniscal tear. what is the treatment? These can occur through either a contact or non-contact injury for example, a pivoting or cutting injury. Sports-related meniscus injuries often occur along with other knee injuries, such as anterior cruciate ligament (ACL) tears. During the exam, your doctor will look for signs of tenderness along the joint line. There are two menisci, a medial one on the "inside" of the knee and a lateral one on the "outside" of the knee. Symptomatic treatment with rest, ice, NSAIDs and/or an unloader brace may help alleviate symptoms in some cases.

6 Types of Meniscus Tears - Orthopaedic Associates of Central Maryland Presumptive subarticular stress reactions of the knee: MRI detection and association with meniscal tear patterns. The Thessaly test is the most sensitive and specific clinical test to diagnose meniscal injury. If you undergo surgery it will likely be followed by physical therapy to optimize knee strength and stability. 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. growth factors) on meniscus tissue is being investigated.2 These are currently only being trialled in younger patients7 and the routine use of most of these technologies is some time away. Biomechanical studies have demonstrated that repair of medial meniscus posterior root tears leads to improved contact mechanics. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. 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). Your doctor will generally ask you how the injury occurred, how your knee has been feeling since the injury and whether you have had other knee injuries. Prospective evaluation of allograft meniscus transplantation: a minimum 2-year follow-up.

What Is a Tear of the Anterior Horn of the Lateral Meniscus? AAOS OVT - Suture Bridge Fixation for Posterior Cruciate Ligament 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. Repair is sometimes attempted even with these tear types, particularly when the patient is young and substantial loss of meniscal tissue would lead to an unacceptable risk of future arthritis.11 Repair of these challenging tear types should only be attempted when the meniscal tissue is of good quality and a stable result is achievable. The tear can be seen as a white line through the dark body of the meniscus. 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. . Know the reason for your visit and what you want to happen. what is the best possible treatment? The tear results in a vertical signal abnormality on sagittal MR images. The menisci the medial meniscus and lateral meniscus - are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). 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. Verdonk PC, Demurie A, Almqvist KF, Veys EM, Verbruggen G, Verdonk R. Transplantation of viable meniscal allograft. Grade 3 is a true meniscus tear and an arthroscope is close to 100 percent accurate in diagnosing this tear. This provides a clear view of the inside of the knee. Studies have also reported that patients who underwent a repair of the posterior root in the medial meniscus slowed the progression of arthritic changes compared with those who had a meniscectomy; although, this did not completely prevent the arthritic changes. Each knee has two C-shaped pieces of cartilage known as menisci. 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. During weight-bearing activities, the menisci dissipate axial loads and contain hoop stresses. Any tears appear as white lines. Oblique tears commonly cause flaps and flaps are generally not good. De Carlo M, Armstrong B. New advances in musculoskeletal pain. Great Britain: Hodder Arnold, 2005. This technique allows for anatomic reduction and fixation of the meniscal root by restoring the joint contact pressure and area similar to the intact state.

The role of preoperative MRI in knee arthroscopy: a retrospective analysis of 2,000 patients. As stated above, the most common cause of Posterior Horn Medial Meniscus Tear can be trauma to the knee which can be sustained due to a sporting injury, a slip and fall, a blunt trauma to the knee, and in majority of the cases natural degeneration of the meniscus due to the work load of the knee. The meniscus is a piece of rubber-like cartilage in the knee situated within the femur and tibia, or thigh bone and shin bone. Arthroscopic repair of meniscal tears extending into the avascular zone in patients younger than twenty years of age. Additionally, the individual will not be able to move the joint due to pain.

The tear should be eight millimeters or more in length, as shorter peripheral longitudinal tears are less likely to be symptomatic and may heal spontaneously. The accuracy of physical diagnostic tests for assessing meniscal lesions of the knee: a meta-analysis. Medial and lateral menisci are crescent-shaped fibrocartilage structures that provide joint congruity, stabilization and lubrication and act as shock absorbers for joint preservation. Acta Orthop Scand 1982;53:9759. J Fam Pract 2001;50:93844. Singapore: World scientific, 2010. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a).
