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.
Meniscus Tears: Why You Should Not Let Them Go Untreated Indications for meniscal root repair are acute, traumatic root tears in patients with nearly normal or normal cartilage (Outerbridge grade 0 to 2) and chronic symptomatic root tears in active patients without significant pre-existing osteoarthritis (OA). Bucket-handle tears are actually a form of longitudinal tear in which subsequent displacement of the inner rim of the tear results in a configuration that resembles the handle of a bucket (11a). Bull NYU Hosp Jt Dis 2010;68:8490. Although C, a vertical tear, is commonly used to describe such an appearance, the better answer is D, a longitudinal tear. The parrot beak shape of an oblique tear (arrow) is readily apparent on (7a) a proton density-weighted axial image of the menisci. (11a) A 3D illustration of a bucket handle tear demonstrates that these tears actually are longitudinal in nature (arrows), coursing parallel to the c-shaped fibers of the meniscus. Knee pain: Depending on your duration of symptoms you can at least start off with physical therapy, a knee sleeve, and if there is arthritis present consider a c Read More oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. In the early days of MR, it was often felt that the role of MR was simply to identify whether a tear was present or not, and treatment of meniscal tears was largely composed of operative resection. Grade 3 is a true meniscus tear and an arthroscope is close to 100 percent accurate in diagnosing this tear. Although the pain improved, the patient could not flex her knee joint deeply.

AAOS does not endorse any treatments, procedures, products, or physicians referenced herein. Fax 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. 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. Medial meniscal posterior root tears represent an often unrecognized pathology with potentially devastating long-term effects. 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.

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. 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. The best known displaced tear that is amenable to repair is the bucket-handle tear. 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. Video chat with a U.S. board-certified doctor 24/7 in less than one minute for common issues such as: colds and coughs, stomach symptoms, bladder infections, rashes, and more. Both longitudinal and radial tears may appear vertical on MR images (5a,6a), but longitudinal tears extend parallel to the c-shaped circumference of the meniscus, whereas radial tears lie perpendicular to the meniscal circumference.

Peripheral meniscal tears are among the most common causes of meniscal pathology, particularly occurring in conjunction with anterior cruciate ligament (ACL) injury or deficiency. This makes the medial meniscus less mobile and is one reason why the medial meniscus is more prone to injury.3 In adults, only the periphery of the meniscus remains vascularized. What is the posterior horn of the medial meniscus? Arthroscopic meniscus repairs typically takes about 40 minutes. We believe these tears are more degenerative in nature, and there is no evidence to support that by repairing these medial meniscal root tears, knee degeneration will be postponed or stopped. A flap tear is a descriptive term that refers to a situation where the meniscus tears within its midsubstance, usually in a predominantly horizontal pattern, and then the upper or lower component of the torn meniscus becomes displaced from its site of origin (14a).8 These tears are most common at the medial meniscal body, and when displaced, the flap component may migrate into the superior or inferior meniscal gutter (15a,15b). Meniscal repair is a more difficult surgical technique and requires a motivated, diligent patient in order to be successful. Posterior medial meniscal root tears are often times degenerative, but these can also occur with multi-ligament knee injuries in the acute setting.
