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. Large tears to the meniscus may require surgical repair or removal. In terms of a meniscus tear, the doctor can categorize the injury ...
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 have anterior and posterior horns that meet in the intercondylar area of the tibia. [13] Medial meniscus is bigger, less curved, and thinner. Its posterior horn is thicker (14mm) than the anterior horn (6mm). [13] The lateral meniscus is smaller, more curved (nearly circular), and has more uniform thickness than medial meniscus ...
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 larger semilunar medial meniscus is attached more firmly than the loosely fixed, more circular lateral meniscus. The anterior and posterior horns of both menisci are secured to the tibial plateaus. Anteriorly, the transverse ligament connects the 2 menisci; posteriorly, the meniscofemoral ligament helps stabilize the posterior horn of the ...
Between these, the synovial membrane passes in front of the anterior and posterior cruciate ligaments, why these ligaments are both intracapsular and extra-articular with their tibial attachment located exactly on the cartilage margin. Both the lateral and medial meniscus are, however, located within the synovial capsule. [2]
The posterior meniscofemoral ligament (also known as the ligament of Wrisberg) is a small fibrous band of the knee joint. It attaches to the posterior area of the lateral meniscus and crosses superiorly and medially behind the posterior cruciate ligament to attach to the medial condyle of the femur .
High quality MRI images (1.5 T magnet or higher [22]) of the knee can be extremely useful to diagnose injuries to the posterolateral corner and other major structures of the knee. [23] While the standard coronal, sagittal and axial films are useful, thin slice (2 mm ) coronal oblique images should also be obtained when looking for PLC injuries ...
