How much more accurate is computer assisted surgery?
Until the advent of computer navigation we were able to align the joint replacement device to within 7 to 9 degrees of optimal alignment. With computer navigation we can be reasonably certain of achieving an alignment within 3 degrees. That is better than a 50 percent improvement. So how much longer will a computer assisted hip or knee replacement last? Longevity of a replacement varies from individual to individual. That being said, a standard knee implant without the assistance of computer navigation typically lasts 10 to 15 years. With computer-assisted surgeries, a knee implant is more precisely aligned to minimize joint wear, potentially extending the life of the implant to up to 30 years. We cant say that with absolute certainty yet because we dont have enough data but we will in the years ahead. Does computer navigation help shorten the recovery period for knee and hip surgery? There is no conclusive evidence that it does. However, the technology is a perfect complement to minim
