Inside human anatomy, the knee is the leg joint connecting the femur and the tibia.

Human anatomy
the knee occurs as complex, compound, condyloid kind of a synovial joint. It actually is ii separate joints. A femoro-patellar joint consists of the patella, or "kneecap", the therefore-supposed "sesamoid bone" which sits inside a tendon of a prior thigh muscles, & the patellar groove on the front of the femur through which it slides. A femoro-tibial joint links a thighbone, or even thigh bone, by owning a tibia, the main bone of the (moo) leg. a joint is bathed around a viscous fluid which is contained within the "synovial" membrane,Or even "joint capsule". A recess behind a knee is known as a "popliteal fossa".

Ligaments
A knee is associated by using a as a result ligaments: anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), capsular ligament, ligamentum patellae, medial collateral ligament (MCL a.k.the. tibial indirect ligament), lateral collateral ligament (LCL a.k.the. fibular indirect ligament), & oblique popliteal ligament. the MCL protects the medial side of the knee from either existence bent open by a stress applied to the lateral side of the knee (a valgus click), while on the other hand a LCL protects the lateral side from either an within bending force (a varus force). A critically crucial ACL prevents a shinbone from either existence pushed as well far prior relative to the thighbone.

Menisci
Which are actually scomberesox saurus elements in a knee joint which help to protect a ceases of a bones from either rubbing in every more & to profits deepen a tibial sockets into which the femoris attaches. There are 2 menisci within both knee, a medial meniscus & a lateral meniscus. Either or even even each can be cracked, or torn, while a knee is forcefully rotated and/or bent.

Movements
A knee permits a as a consequence movements: flexion, extension, locking, unlocking, and slight rotation. A ligaments & menisci, along by owning a muscles which traverse a joint, end movement beyond a knee's meant range of motion.

Injury
Inside sports like skiing and soccer, or even even further sports that require smashing stress to the knees, these are commons to tear 1 or more ligaments or gristle. Especially debilitating is the unluckily most common triad of torn medial collateral & prior cruciform ligaments & the torn medial meniscus. Prior to a advent of arthroscopy and arthroscopic surgery, patients having surgery for this injury expected at least nine months of rehabilitation. Using todays techniques, such patients can be walking forswearing crutches witharound 2 weeks, & swimming a select few sports in however two or three months.

Additionally to getting freshly surgical procedures, on-going search is seeking into underlying problems which might increase the likeliness of an jock suffering a severe knee injury. These findings might lead to efficacious preventative measures.

Non-biped anatomy
Leg joints of quadruped mammals and of insects that have functions similar to the articulatio genus come too known as knees, despite significant differences. Particularly, a homologies in the limbs of bipeds & of quadrupeds come extensive, however typically a area serving corresponding functions are nin homologous to both more, & a homologous area own different functions, to the extent that cerebration of horses when going on their tiptoes and fingertips can be a step toward abandoning misconceptions.
