The test is positive if symptoms are reproduced on rotation 10. It is caused by direct impact in contact sports or twisting. (16a) Sagittal and (16b) axial proton density weighted images reveal a very large radial tear (arrows) that extends broadly across the entire width of the anterior body of the lateral meniscus. An experimental study in dogs. The relationships among MM radial/oblique tears, MM extrusion (MME), and the effect of arthroscopic meniscal repair are not established. 15 Koski JA, Ibarra C, Rodeo SA.

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. For information:Questions and Answers for Patients Regarding Elective Surgery and COVID-19. Case Discussion Longitudinal tears, also known as vertical tears, occur perpendicular to the tibial plateau and parallel to the long axis of the meniscus splitting the meniscus into inner and outer parts. Meniscus tears simply do not heal on their own, regardless of conservative treatment. Successful outcome and patient satisfaction after medial meniscal root repair are established initially upon appropriate diagnosis and patient selection. However, meniscus tears do not always appear on MRIs. McMurray (Figure 1) and Apley tests (Figure 2) are often positive, although these are specific but not sensitive specificity being 5798% and 8099%, and sensitivity being 1066% and 1658% respectively.2,9 The most useful clinical test for meniscal injury is the Thessaly test, which is demonstrated in Figure 3. Usually you will be able to leave the hospital the same day. and oblique tear . Referral is also indicated if the diagnosis is uncertain for review and to access MRI. Arthroscopy.

The meniscus comma sign has been described for displaced flap tears of the meniscus. Oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. 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). In this case, a portion may break off, leaving frayed edges. However, coronal sections may reveal the presence of meniscal extrusion or vertical defects, and sagittal sections may reveal the ghost sign (absence of an identifiable meniscus or increased signal replacing the normal hypointense signal of meniscal tissue). The meniscus root attachment aids meniscal function by securing the meniscus in place and allowing for optimal shock-absorbi This type of tear has an unusual pattern. This puts tension on a torn meniscus. The younger population, particularly males with knee instability, is most commonly affected by this type of tear [56]. Meniscal Tears - Knee & Sports - Orthobullets History, clinical findings, magnetic resonance imaging, and arthroscopic correlation in meniscal lesions.

Choose a doctor and schedule an appointment. 2010. They include: Other nonsurgical treatment. If the tear cant be repaired, occasionally the meniscus can be surgically trimmed. If a repair is attempted within meniscal tissue that is questionably vascular or non-vascular, healing enhancement techniques such as the use of fibrin clot and the creation of channels that communicate with the vascular zone may be utilized.10. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. A tear can also develop slowly as the meniscus loses resiliency. During weight-bearing activities, the menisci dissipate axial loads and contain hoop stresses. This tear pattern was historically unrecognized, although more recently it has been suggested this hidden pathology may account for nearly 80% of the total knee replacements in patients younger than 60 years. 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. The tear results in a vertical signal abnormality on sagittal MR images. As such, it is critical to repair medial meniscal root tears during ACL reconstruction to help stabilize the knee, as well as to decrease stresses that the graft experiences. Two months later, the post-operative image (17b) reveals a repaired, normal appearing lateral meniscal body (arrow), with resolution of the previously seen displaced fragment.

Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites. Longitudinal tears do not disrupt the circumferential architecture of the meniscus, and thus repair of longitudinal tears leads to a meniscus with relatively normal biomechanical function. apalia R, Del Buono A, Osti L, Denaro V, Maffulli N. Meniscectomy as a risk factor for knee osteoarthritis: a systematic review. MR imaging is reliable in the detection of meniscal tears and identification of meniscal fragmentation and displacement [1, 2, 3, 4].Displaced meniscal fragments are often clinically significant lesions requiring surgical intervention and, therefore, are important to identify.
