Human anatomy The knee is a complex, compound, condyloid variety of a synovial joint which hovers. It actually comprises two separate joints. The femoro-patellar joint consists of the patella, or "kneecap", a so-called "sesamoid bone" which sits within the tendon of the anterior thigh muscles, and the patellar groove on the front of the femur through which it slides. The femoro-tibial joint links the femur, or thigh bone, with the tibia, the main bone of the (lower) leg. The joint is bathed in a viscous fluid which is contained inside the "synovial" membrane, or "joint capsule". The recess behind the knee is called the "popliteal fossa". This article is about a joint in zootomical anatomy. ...

Menisci These are cartilaginous elements within the knee joint which serve to protect the ends of the bones from rubbing on each other and to effectively deepen the tibial sockets into which the femur attaches. There are two menisci in each knee, the medial meniscus and the lateral meniscus. Either or both may be cracked, or torn, when the knee is forcefully rotated and/or bent. In anatomy, a meniscus is either of two parts of the human knee. ...
The medial meniscus (internal semilunar fibrocartilage) is nearly semicircular in form, a little elongated from before backward, and broader behind than in front; its anterior end, thin and pointed, is attached to the anterior intercondyloid fossa of the tibia, in front of the anterior cruciate ligament; its posterior end is...
The lateral meniscus (external semilunar fibrocartilage) is nearly circular and covers a larger portion of the articular surface than the medial meniscus. ...
Movements The knee permits the following movements: flexion, extension, locking, unlocking, and slight rotation. The ligaments and menisci, along with the muscles which traverse the joint, prevent movement beyond the knee's intended range of motion. In anatomy, Flexion is movement whereby bones or other objects are brought closer together. ...
In metaphysics, extension is the property of taking up space; see Extension (metaphysics). ...
Locking can refer to: Securing some physical object using a Lock. ...
Injury In sports such as wrestling, basketball, competitive swimming, American football, Australian rules, skiing and soccer, or other sports that involve great stress to the knees, it is common to tear one or more ligaments or cartilages. Especially debilitating is the unfortunately common triad of torn medial collateral and anterior cruciate ligaments and a torn medial meniscus. Before the advent of arthroscopy and arthroscopic surgery, patients having surgery for this injury required at least nine months of rehabilitation. With current techniques, such patients may be walking without crutches in two weeks, and playing some sports in but a few months. In Australian rules football, knee injuries are among the most common, with a great deal of controversy caused in ruck contests, where the crashing of two knees during the leap has caused injuries to numerous players. This forced new rule changes in the AFL for the 2005 season. The Wrestlers from Uffizi Gallery, Florence. ...

Animal anatomy In humans the knee refers to the joints between the femur, tibia and patella. In quadrupeds, particularly horses and ungulates the term is commonly used to refer to the carpus, probably because of its similar hinge or ginglymus action. The joints between the femur, tibia and patella are known as the stifle in quadrupeds. In insects and other animals the term knee is used widely to refer to any ginglymus joint.
