10. Joint Replacement Surgery | Please explain the basic operation of the Mako system?
Dr. DiGiovanni: So through the through the use of the cats can we give that information to the
Mako system the Mako system now understands the size and shape
three-dimensionally of a person’s knee joint.
In this surgery we do our dissection the same way that we would do
with standard instrumentations, and then we insert pins which hold a
system of reflective discs.
And these reflective discs are picked up by two eyes on the computer system, and now the computer can see where the joint is in space and then we register the joint.
We have a wand, and that wand is a very specific size and that one has its four reflective discs we will touch different places on the joint so that now that the knee that the computer
knows where this joint is in space.
We will rotate the leg around the axis of the hip so now the computer knows, by watching the array move in a circle, it can determine where the center of rotation of the hip joint is.
And then we take the wand, the array wand, and will touch the ankle joint to show the
computer where the center of the ankle is.
So now the computer not only has the three-dimensional size and shape of the joint, it knows where the center of
rotation of the hip is, and those were the center of the knee is, and it knows
where the center of the ankle is, so now we can adjust our aies of alignment that
helps us within the bounds of proper alignment to make very subtle
adjustments to help us balance our ligaments.
We want the joint to be the appropriate length, the appropriate angle,
the appropriate rotation, so that all components of that joint fit together
and flow together in a seamless functional fashion.
