Abstract

Dynamic magnetic resonance imaging MRI techniques have created new opportunities to study muscle function in vivo before and after surgery This commentary is on the use of cine phase contrast MRI to study the function of the rectus femoris muscle after surgical transfer Rectus femoris transfer surgery is performed to correct a stiffknee gait in persons with cerebral palsy In this procedure the distal tendon of the rectus femoris is moved posterior to the knee and sutured to one of the hamstring tendons The surgery is thought to convert the rectus femoris from a knee extensor to a knee flexor however the outcomes are inconsistent and it is not known if the surgery successfully converts the muscle to a knee flexor Cine phase contrast cinePC MRI allowed us to visualize the motion of the knee flexor and extensor muscles and to quantify the velocities of the muscles during knee motion
