The squat, performed with both feet flat on the floor, might be easier during the earlier stages of rehabilitation. Disagreement exists as to whether the individual components of the quadriceps femoris can be preferentially activated, i.e., that one muscle component is activated to a greater degree of its maximum voluntary contraction ability than the remaining components. Strengthening this muscle is particularly important for knee rehabilitation as it helps control the position of the patella (kneecap).
