People who suffer from arthritis sometimes end up needing a total knee replacement. Most do well after surgery, but some continue to have problems. But computer technology may make that less likely.
A knee replacement is a common orthopedic procedure but some patients are trying a new procedure in which surgeons use computer technology.
The Stryker Navigation System is designed to make knee replacement surgery more precise. The surgeons use infrared beacons to map the position of the leg bone and knee joint. The computer then calculates the ideal alignment of the bones and helps the surgeon place the artificial joint at the proper angle.
The new computer system helps to cut down on mistakes, but it's only been FDA approved for about a year. So it is to soon to tell if patients will do better in the long run.
