Dr. Russinoff's research on Computer Navigation for Knee Replacement Surgery and Hip Replacement Surgery was recently accepted for presentation at the Eastern Orthopaedic Society Meeting in October, 2008!

Computer-assisted surgery allows surgeons to align the patient's knee replacement with a degree of accuracy not possible with the naked eye.  Using an infrared camera and sensors on the instruments, the computer gives real-time feedback to the surgeon, like a GPS system. The computer tells the surgeon how much bone is being cut to the millimeter and what angle the bone is being cut to within a fraction of a degree.

By placing the knee implants more accurately they should last longer and allow the knee replacement to function more properly.  There is less bleeding with computer navigated knee replacements because we do not need to drill a hole in the femur to determine the angle to cut the bone!  There is less of a risk of needing a blood transfusion with computer navigated knee replacements.

Here are some pictures of the data the computer provides:
