The knee is a condylar joint, capable of hinge-like movement allowing us to bend our knee. It also has some rotational movement. Muscles, ligaments and tendons provide for this movement at the knee joint. A group of four muscles, often called the quadriceps, act as a strap over the front of the knee. The quadricep muscles include the vastus medialis, vastus intermedius, vastus lateralis and rectus femoris. These muscles connect from the thigh to a point on the patela, or knee cap. The quadriceps help extend or straighten the knee, such as when kicking a football. Three muscles over the back of the knee are responsible for bending the knee. These muscles are often called the hamstrings, and include the biceps femoris, semitendinosus and semimembranosus. Interested in learning more about the knee muscles?
