Meniscal tears are the most common lesions followed by the meniscal cyst. AJR 2000; 174:161-164. Meniscal tears are common sports-related injuries in young athletes and can also present as a degenerative condition in older patients. 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. The medial meniscus is on the innermost side of your knee (the C-shaped curve faces in toward your body, the opposite knee).

The vertical flap tear is a displaced type of radial tear that often occurs in the posterior medial meniscus. 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.

Without nutrients from blood, tears in this "white" zone with limited blood flow cannot heal. Nonsteroidal anti-inflammatory drugs (NSAIDs). Meniscus tears are either degenerative or acute. Complex or degenerative tears are where two or more tear patterns exist. In fact, the tear will most likely get bigger leading to additional damage if not taken care of soon. Both of these factors increase contact forces across the joint, leading to accelerated osteoarthritis and predisposing the patient to the development of subchondral insufficiency fractures.7. Know what to expect if you do not take the medicine or have the test or procedure. Meniscal root tears, less common than meniscal body tears and frequently unrecognized, are a subset of meniscal injuries that often result in significant knee joint disorders.

This "C" shaped cartilage helps disperse impact and displace force exerted upon the knee while walking, running, and other mild to high-energy and impact motions. The second patient reviewed in this video is an 11-year-old girl who fell while playing tag and hit the front of her left lower leg. Another exam finding is palpating the anteromedial joint line, while placing a varus stress on a fully extended knee and feeling for meniscal extrusion. This leads to decreased contact area and increased contact pressure and ultimately results in joint overloading and degenerative changes in the knee similar to a total meniscectomy state.
