Treatment for a meniscus tear will depend on its size, what kind it is, and where it's located within the cartilage. Displaced meniscal tears are by definition unstable, and should be repaired relatively quickly, as displaced meniscal fragments may fibrose and distort, making delayed repair difficult or impossible. This part of the tibia is also known as the tibial plateau. 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. Rotator Cuff and Shoulder Conditioning Program. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion.

Disclosures: LaPrade reports he is a consultant for and receives royalties from Arthrex, Ossur and Smith & Nephew. Meniscal repair is a more difficult surgical technique and requires a motivated, diligent patient in order to be successful. The degenerative aetiology and reduced vascularisation secondary to ageing also means that meniscal tears in the elderly population are less likely to be amenable to surgical management;7 only about 6% of patients over 40 years of age have operable lesions.24 To prevent re-injury of the meniscus, activity modification is important for example, ceasing sports such as soccer or netball. 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.

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. 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. Arthroscopy 2006;22:77180. Arthroscopy. The menisci help to transmit weight from one bone to another and play an important role in knee stability.

The one towards the back of leg is the posterior horn. 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.

If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically. Lim HC, Bae JH, Wang JH, Seok CW, Kim MK. Additional pain may be felt when flexing or twisting the knee. 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. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. The typical meniscal pain profile comprises well localised joint-line pain (with medial pain generally being indicative of a medial tear and vice-versa). Depending on the cut thickness, axial MRI images may display the root tear (Figure 3).
Double posterior cruciate ligament sign | Radiology Reference Article Trauma to medial collateral ligament usually also involves medial meniscus. 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). Because a torn meniscus is made of cartilage, it won't show up on X-rays. If you have a follow-up appointment, write down the date, time, and purpose for that visit.
