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 ...
A: The bottom of a concave meniscus. B: The top of a convex meniscus . In physics (particularly fluid statics ), the meniscus ( pl. : menisci , from Greek 'crescent') is the curve in the upper surface of a liquid close to the surface of the container or another object, produced by surface tension .
Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old. Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability.
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.
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 ...
Meniscus may refer to: Meniscus (anatomy) , crescent-shaped fibrocartilaginous structure that partly divides a joint cavity Meniscus (liquid) , a curve in the upper surface of liquid contained in an object
The transverse ligament is reported in 58 per cent of subjects and is thus the most prevalent of four described meniscomeniscal ligaments. The other ligaments, all three of which are reported with a frequency of less than 4 per cent, are the posterior transverse ligament, described as a bundle of fibers connecting the posterior horns of the menisci; and the medial and lateral oblique ligaments ...
The lateral meniscus has firm attachments medially to the intercondylar area via the ends of the meniscus, and posteromedially via the posterior meniscofemoral ligament, which attaches the posterior limb of the meniscus to the posterior cruciate ligament and medial femoral condyle.
