oblique tear of medial meniscus oblique tear of medial meniscus

Whats the best way to treat an oblique fracture? The tear results in a vertical signal abnormality on sagittal MR images. The medial meniscus is C-shaped, while the lateral meniscus is more . However, whether they will respond well to surgery depends on the type of tear, the location, and blood flow in the area where the tear occurred. How to Treat Posterior Horn Medial Meniscus Tear. The treatment of these type of tears can be either arthroscopy (surgery through a tiny hole in knee) or conservative. Description of Medial Meniscus Tear The medial meniscus is an important shock absorber on the inside (medial) aspect of the knee joint. w/severe pain? X-rays and MRIsallow the doctor to evaluate the bone and soft tissue at the knee. Krych AJ, McIntosh AL, Voll AE, Stuart MJ, Dahm DL. 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. Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. The medial meniscus is the cushion that is located on the inside part of the knee. Oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. As recognition of the critical function of the menisci in normal biomechanical function of the knee has grown, attempts at preserving meniscal tissue via repair as opposed to partial meniscectomy have also gained favor. Metcalf MH, Barrett GR. The knee meniscus: structure-function, pathophysiology, current repair techniques, and prospects for regeneration. Arthroscopic repair An arthroscope is inserted into the knee to see the tear. Arthroscopic partial meniscectomy The goal of this surgery is to remove a small piece of the torn meniscus in order to get the knee functioning normally. It is important that these root avulsions are anatomically repaired back to the bone. Deep leg presses and squats greater than 70 of knee flexion should be avoided for at least 4 months after surgery. (9a) This irregular tibial surface tear (arrow) clearly lies within the peripheral, red zone, of the meniscus. During the exam, your doctor will look for signs of tenderness along the joint line.

Meniscal tears within the body of the meniscus or at the meniscocapsular junction represent a well-understood and manageable condition encountered in clinical practice. 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. I could not really walk on it. 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. This provides a clear view of the inside of the knee. The outer one-third of the meniscus has a rich blood supply. These can occur through either a contact or non-contact injury for example, a pivoting or cutting injury. These tears occur within the avascular zone of the meniscus where there is no blood supply. swelling - this usually happens several hours after you injure your meniscus. 9 Lecase LK, Helms CA, Kosarek FJ, Garret WE. Likewise, physical exam findings of an effusion, a positive McMurray test and a positive Apley grind test are not usually present. Tears that lie within or contact the red zone are also more likely to be amenable to meniscal repair. 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. For information:Questions and Answers for Patients Regarding Elective Surgery and COVID-19. 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.

Herrlin S, Hallander M, Wange P, Weidenhielm L, Werner S. Arthroscopic or conservative treatment of degenerative medial meniscal tears: a prospective randomised trial. Because the pieces cannot grow back together, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically. pivoting). (3a) A fat-suppressed proton density-weighted axial image through the knee joint demonstrates the C-shaped menisci. (6a) A radial tear of the body of the lateral meniscus also appears vertical on sagittal MR images (arrow), though in the case of radial tears, the lesion is oriented perpendicular to the c-shaped fibers of the meniscus. Arthroscopy 1998;14:8249. 1871 LPGA Blvd., Daytona Beach, FL 32117. A meniscus tear can lead to knee instability, an inability to move the knee normally, and chronic knee pain. M23.322 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. These are often 'bucket-handle tears', in which there is a vertical or oblique tear in the posterior horn running toward the anterior horn,5 forming a loose section which remains attached anteriorly and posteriorly.1 In older patients, tears are generally due to degeneration associated with ageing and tend to be horizontal tears. London;1897. A referral to an orthopedic physician should result in guidance it means you need to see in orthopedist and get an opinion as to whether. Helms CA, Laorr A, Cannon WD, Jr. One of the main tests for meniscus tears is the McMurray test. Matthew H.

All rights reserved. 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. Non-operative treatment of degenerative posterior root tear of the medial meniscus. If you undergo surgery it will likely be followed by physical therapy to optimize knee strength and stability. Liodakis E, Hankemeier S, Jagodzinski M, Meller R, Krettek C, Brand J.

There are numerous treatments for meniscus tears, but treatment generally begins conservatively depending on the location, type, and size of the tear. 3rd Edition. AAOS does not endorse any treatments, procedures, products, or physicians referenced herein.

Disclosures: Blake and Johnson report no relevant financial disclosures. Progressive weight-bearing begins at 6 weeks, with full weight-bearing at 8 weeks. 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.
