If you would like to learn more about the anatomy of the knee, please watch this KNEE ANATOMY VIDEO.

The knee is a complex joint that flexes, extends, and twists slightly from side to side.
The knee is the meeting point of the femur in the upper leg and the tibia in the lower leg. The fibula, the other bone in the lower leg, is connected to the knee joint. However, it is not directly affected by the hinge joint action.  To learn more about fractures to the tibia and fibula, please go to: Tibia and Fibular Fractures.  Another bone, the patella, is at the center of the knee.
Two concave pads of cartilage called menisci minimize the friction created at the meeting of the ends of the tibia and femur.
There are also several key ligaments, a type of fibrous connective tissue, that connect these bones.

The four key ligaments of the knee are:

Anterior cruciate ligament (ACL)
Medial collateral ligament (MCL)
Lateral collateral ligament (LCL)
Posterior cruciate ligament (PCL)

Knee Tendons

There are several tendons in the knee.  Tendons are defined as where the muscle attaches to bone.  The main tendons of the knee are the patellar tendons.  The suprapatellar tendon is where the quad attaches to the top of the patella.  The infrapatellar tendon is where it attaches to the bottom of the patella or knee cap.
