Millions of Americans suffer pain caused by joints that are worn out from years of wear and tear. When the pain gets too bad, a knee replacement is your only option. Mayo Clinic doctors are working to make these operations better. They're using high-tech computers that will likely help your new knee last longer.
The technology is still too new to see how patients do long term, but here's how it works: during surgery, Dr. O'Connor attaches markers to the knee. Next, she uses a probe to draw the contours of the joint. The computer takes that information and makes a model of the knee. The model shows doctors where to place the joint to get the best fit.
