Artwork showing the structure of the knee joint

Artwork showing the structure of the knee joint which articulates the femur (upper centre) with the tibia and fibula (bottom). The knee is a strong hinge joint held in alignment by ligaments (light purple) and muscles; it is capable of flexion, extension and very slight rotation. The synovial membrane (blue) forms a large pouch, also known as bursa, which contains a clear fluid that lubricates the joint and eases its movement. The thin horizontal (purple) feature at centre between the femur and tibia shows the position of the menisci; these are discs or cartilaginous tissue which also reduce friction during joint movement. The patella is seen at centre right
