It divides into two branches, one of which supplies the vastus medialis, anastomosing with the highest genicular and medial inferior genicular arteries; the other ramifies close to the surface of the femur, supplying it and the knee-joint, and anastomosing with the lateral superior genicular artery.

For example, high EMG signals in the vastus medialis ( a quadriceps muscle ) and low EMG signals in the biceps femoris ( a hamstring muscle ) would indicate that the user is extending his / her leg, therefore the exoskeleton would provide torque on the knee to help straighten the leg.

A division of the vastus medialis muscle into two groups of fibers has been hypothesized, a long and relatively inline group of fibres with the quadriceps ligament, the " vastus medialis longus "; and a shorter and more obliquely oriented with group of fibbres, the " vastus medialis obliquus ".

The vastus medialis and vastus intermedius appear to be inseparably united, but when the rectus femoris has been reflected a narrow interval will be observed extending upward from the medial border of the patella between the two muscles, and the separation may be continued as far as the lower part of the intertrochanteric line, where, however, the two muscles are frequently continuous.
