The knee joint is 3 joints in1
The Tibiofemoral joint is a hinge joint permitting flextion and extension.
The Femoralpatellar joint is a plane joint where the patella glides across the distal end of the femur during knee flextion.
Structurally it is a bicondylar joint allowing some rotation when the knee is partially flexed and when the knee is extending.

Ligaments A ligament is a tough band of fibrous tissue that connects bone to bone or bone to cartilage and supports and strengthens joints.

Bursae-A bursa (plural bursae) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint. This helps to reduce friction between the bones and allows free movement. Bursae are filled with synovial fluid and are found around most major joints of the body.
