Most oblique meniscus tears are happen in the posterior third of the medial meniscus. A tear of the anterior horn of the lateral meniscus is damage to the front part of one of the two structures that act as shock absorbers between the thigh bone and the lower leg, explains The Steadman Clinic. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). Meniscal tears may be categorized into five common configurations, including horizontal, longitudinal, radial, oblique (parrot-beak), and complex.5 Horizontal tears, the most common meniscal tear pattern, lie parallel to the tibial plateau and separate the meniscus into upper and lower parts (4a,4b). 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. Sometimes this type of tear can heal on its own but it may require surgery if symptoms dont subside.

Bull NYU Hosp Jt Dis 2010;68:8490. Evaluation of meniscal injury accounts for most requests for MR imaging of the knee at most institutions. The meniscus is a piece of rubber-like cartilage in the knee situated within the femur and tibia, or thigh bone and shin bone. In case of an open or unstable fracture, the bone may protrude out of the skin surface and be exposed to environmental contaminants. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. In this short surgical video, a degenerative meniscus tear is smoothed down with a motorized shaver during a partial meniscectomy. Those that extend through the entire width of the meniscus are particularly harmful (16a,16b), and even if such tears appear stable following repair, they are unlikely to regain the ability to provide hoop stress to the meniscus.13 Radial tears have therefore classically been treated with partial meniscectomy, though evolving surgical techniques have led to successful reports of the repair of radial tears that communicate with the meniscal periphery.11 A recent report has even described the successful repair of radial tears of the medial meniscal root,14 utilizing a tibial tunnel through which sutures are placed in the avulsed meniscus, a technique similar to that used in patients undergoing meniscal transplantation.
