A meniscus (pl.: menisci or meniscuses) is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. [1] In humans , they are present in the knee , wrist , acromioclavicular , sternoclavicular , and temporomandibular joints ; [ 2 ] in other animals they may be present ...
Each meniscus has an outer vascular zone (red-red zone), which has a good blood supply and healing potential as well as a central avascular zone (white-white zone), which has limited healing capability. [2] The medial meniscus is more prone to injury due to its firm attachment to the joint capsule and limited mobility.
A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci.When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae.
The meniscus is a C-shaped piece of fibrocartilage located at the peripheral aspect of the knee joint that offers lubrication and nutrition to the joint. Each knee has two menisci, medial and lateral, whose purpose is to provide space between the tibia and the femur, preventing friction and allowing for the diffusion of articular cartilage.
The lateral meniscus is grooved laterally for the tendon of the popliteus, which separates it from the fibular collateral ligament.. Its anterior end is attached in front of the intercondyloid eminence of the tibia, lateral to, and behind, the anterior cruciate ligament, with which it blends; the posterior end is attached behind the intercondyloid eminence of the tibia and in front of the ...
The medial meniscus has more of a crescent shape while the lateral meniscus is more circular. The anterior aspects of both menisci are connected by the transverse ligament . It is a common site of injury, especially if the knee is twisted.
Dettloff said there’s long been a conservative strain in the city, which once had a John Birch Society presence and led the mask-resistance forces in the early days of the pandemic.
More than half (53.5%) of knee dislocations have an associated torn meniscus. [46] Quadriceps tendon rupture occurs up to 13.1% of the time, and patellar tendon rupture occurs 6.8% of the time. [46] Foot and Ankle A lisfranc injury is a dislocation or fracture-dislocation injury at the tarsometatarsal joints.
