Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, . The treatment of these type of tears can be either arthroscopy (surgery through a tiny hole in knee) or conservative. One or two other small incisions are made for inserting instruments. MR is also able to assess the stability of meniscal tears,6 an important factor, as unstable tears require operative treatment for symptom relief. If the tear cant be repaired, occasionally the meniscus can be surgically trimmed. The vertical flap tear is a displaced type of radial tear that often occurs in the posterior medial meniscus. The loss of the central attachment of the posterior horn may allow extrusion of the body of the meniscus relative to the joint (13a). If you have a meniscus tear, this movement may cause pain, clicking, or a clunking sensation within the joint. Deep leg presses and squats greater than 70 of knee flexion should be avoided for at least 4 months after surgery.

More often, the patient will complain of joint line pain with a minor traumatic event, such as squatting. (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. The treatment may be conservative or sometimes surgery may be required to treat the fracture. My husband has complex tear of the body and posterior horn of the medial meniscus with flap components, horizontal oblique tear of the body and posterior horn lateral meniscus.

Krych AJ, McIntosh AL, Voll AE, Stuart MJ, Dahm DL. (13a) A coronal image from another patient with a medial meniscal root tear demonstrates associated severe medial subluxation of the meniscal body (arrow).

Proton weighted sagittal image demonstrates an example of a posterior horn medial meniscal horizontal tear (white arrow). Although surgical repair has led to improved patient-reported function, there are conflicting reports on the progression of cartilage degeneration. Henning C, Lynch M, Clark J. Vascularity for healing of meniscus repairs. 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). An awkward twist when getting up from a chair may be enough to cause a tear in an aging meniscus. These tears occur within the avascular zone of the meniscus where there is no blood supply. If you have a meniscus tear, this movement may cause pain, clicking, or a clunking sensation within the joint. Pain is typically medial and activity-related (e.g. Conservative management of the patient with a meniscal 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. Doctors typically provide answers within 24 hours. A meniscus tear can lead to knee instability, an inability to move the knee normally, and chronic knee pain. With a bucket handle tear, a tear forms in the center of your meniscus. 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. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. The medial meniscus has a firmer capsular attachment than the lateral meniscus. Jarit G, Bosco J. Meniscal repair and reconstruction. 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.
