Both collateral ligaments are taut when the knee joint is in extension. With the knee in flexion, the radius of curvatures of the condyles is decreased and the origin and insertions of the ligaments are brought closer together which make them lax. The pair of ligaments thus stabilize the knee joint in the coronal plane. Therefore, damage and ...
The medial collateral ligament (MCL), also called the superficial medial collateral ligament (sMCL) or tibial collateral ligament (TCL), [1] is one of the major ligaments of the knee. It is on the medial (inner) side of the knee joint and occurs in humans and other primates. Its primary function is to resist valgus (inward bending) forces on ...
The MPFL's origin is on the femur between the medial femoral epicondyle and the adductor tubercle, while being superior to the superficial medial collateral ligament. From the origin, it moves anteriorly, and combines with the deep portion of the vastus medialus oblique, inserting to the superomedial side of the patella, creating greater ...
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 ...
Grade III, the PCL is torn completely and the knee can now be categorized as unstable. Grade IV, the ligament is damaged along with another ligament housed in the knee (i.e. ACL). With these grades of PCL injuries, there are different treatments available for such injuries. [citation needed] The posterior cruciate ligament is located within the ...
The two ligaments are called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. [1] The term cruciate is Latin for cross. This name is fitting because the ACL crosses the posterior ...
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 ...
Cruciate ligaments (also cruciform ligaments) are pairs of ligaments arranged like a letter X. [1] They occur in several joints of the body, such as the knee joint, wrist joint and the atlanto-axial joint. In a fashion similar to the cords in a toy Jacob's ladder, the crossed ligaments stabilize the joint while allowing a very large range of ...
