the vastus lateralis (), also called the "vastus externus" is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh. together with other muscles of the quadriceps group, it serves to extend the knee joint, moving the lower leg forward. it arises from a series of flat, broad tendons attached to the femur, and attaches to the outer border of the patella. it ultimately joins with the other muscles that make up the quadriceps in the quadriceps tendon, which travels over the knee to connect to the tibia. the vastus lateralis is the recommended site for intramuscular injection in infants less than 7 months old and those unable to walk, with loss of muscular tone.
