Human Knee Structure
The knee is vulnerable to injury and to the development of osteoarthritis.
Human knee structure BUTOI. The knee is a complex joint that flexes extends and twists slightly from side to side. In addition to the bones involved in the knee joint the function. The knee is a modified hinge joint which permits flexion and extension as well as slight internal and external rotation.
Femur the upper leg bone or thigh bone. The knee is a complex joint that. The knee joins the thigh bone femur to the shin bone tibia.
Stability of the joint is governed by a combination of static ligaments dynamic muscular forces meniscocapsular aponeurosis bony topography and joint load. The knee is designed to fulfill a number of functions. As it is primarily stabilized by the ligaments mentioned above any unnatural movement of the knee such as twisting pivoting sudden change of direction or a forceful blow can cause injury to these structures.
This review contains a concise detailed description of the knee menisci-including anatomy etymology phylogeny ultrastructure and biochemistry vascular anatomy and neuroanatomy biomechanical. The knee is the joint where the bones of the lower and upper legs meet. Functionally the knee comprises 2 articulationsthe patellofemoral and tibiofemoral.
The knee is made up of the kneecap patella cartilage meniscus and ligaments - the anterior cruciate ligament ACL posterior cruciate ligament PCL. Femur is considered as the largest bone in the human body. The femur and the tibia meets at the tibiofemoral joint and patella rests on top of this joint.
Femur is the thigh bone tibia is the shin bone and patella is the small cap like structure which rests on the other two bones. In humans and other primates the knee joins the thigh with the leg and consists of two joints. The menisci of the knee joint are crescent-shaped wedges of fibrocartilage that provide increased stability to the femorotibial articulation distribute axial load.
The 3B Scientific Anatomy Video Knee Joint demonstrates the structure of the knee joint. Knee function is determined in large part by the anatomy of the joint. The knee consists of three bones.
Knee actually consists of three bones femur tibia and patella. Two rounded convex processes known as condyles on the distal end of the femur meet two rounded concave condyles at the proximal end of the tibia. In this image you will find posterior cruciate ligament anterior cruciform ligament lateral meniscus lateral collateral ligament medial meniscus a medial collateral ligament in Human Knee Structure Ligaments.
There are three bones in the knee namely the femur which is the thigh bone tibia which is the shin bone and patella which is the knee cap. The knee also known as the tibiofemoral joint is a synovial hinge joint formed between three bones. Skip to content Professor Adrian Wilson.
Tendons connect the knee bones to the leg muscles that move the knee joint. It is the largest joint in the human body. This is a 3d model of the human knee anatomy.
The knee is a hinge joint that is responsible for weight-bearing and movement. The femur tibia and patella. The largest joint in the body the knee moves like a hinge allowing you to sit squat walk or jump.
It consists of bones meniscus ligaments and tendons. Human Knee Structure Ligaments Anatomy. Explore and learn about the muscle which extend the knee with our.
Normal Anatomy and Biomechanics of the Knee Fred Flandry MD FACSw and Gabriel Hommel MD Abstract. One between the femur and tibia and one between the femur and patella. Patella sits over the other two bones and slides to facilitate the movement.
As the knee joint is a complicated structure subjected to significant biomechanical stress every day it is a common site of injury. The knee is one of the largest and most complex joints in the body.
