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 in other ...
Anterior meniscofemoral ligament is found in 11.8% of the subjects during MRI scan of the knee. [2] It may be confused for the posterior cruciate ligament during arthroscopy. In this situation, a tug on the ligament while observing for motion of the lateral meniscus can be used to tell the two apart. [citation needed]
The greatest displacement of the meniscus is caused by external rotation, while internal rotation relaxes it. [1] During rotational movements of the tibia (with the knee flexed 90 degrees), the medial meniscus remains relatively fixed while the lateral part of the lateral meniscus is displaced across the tibial condyle below.

The articular capsule of the knee joint is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. [1] The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly. [2]
The knee joint contains two crescent-shaped fibrocartilaginous structures, the menisci (medial and lateral), which serve as shock absorbers and stabilize the joint during movement. 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 ...
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 knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
