The medial meniscus is a fibrocartilage semicircular band that spans the knee joint medially, located between the medial condyle of the femur and the medial condyle of the tibia. [1] It is also referred to as the internal semilunar fibrocartilage. The medial meniscus has more of a crescent shape while the lateral meniscus is more circular.
Knee diagram. Structures on the medial side of the knee include the tibia, femur, vastus medialis obliquus muscle, semitendinosus tendon, gracilis tendon, sartorius tendon, adductor magnus tendon, medial head of the gastrocnemius muscle, semimembranosus tendon, medial meniscus, medial patellofemoral ligament (MPFL), sMCL, dMCL, and POL.
The medial meniscus does not have a direct muscular connection. The medial meniscus may shift a few millimeters, while the less stable lateral meniscus may move at least 1 cm. [ citation needed ] In 1978, Shrive et al. reported that the collagen fibers of the menisci are oriented in a circumferential pattern. [ 11 ]
Meniscal repair: Preferred for young patients or those with tears in the vascular (red-red) zone, which has healing potential. Arthroscopic sutures are used to repair the torn meniscus. Partial meniscectomy : [ 7 ] If the tear is in a non-repairable location (white-white zone) or the meniscal tissue is extensively damaged, the displaced ...
Generally, the term "meniscus" is used to refer to the cartilage of the knee, either to the lateral or medial meniscus. Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion. The menisci are also known as "semi-lunar" cartilages, referring to their half-moon, crescent shape.
A piece of fossilized vomit, dating back to when dinosaurs roamed the earth, was discovered in Denmark, the Museum of East Zealand said on Monday.
Likewise, external rotation of the leg can be applied to test the posterior portion of the medial meniscus. [2] The McMurray test is named after Thomas Porter McMurray, [2] a British orthopedic surgeon from the late nineteenth and early twentieth century who was the first to describe this test.
Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that ...
