Computer-Assisted Surgery

Computer-assisted knee replacement surgery allows surgeons to operate with smaller incisions and greater precision:

  • Surgeons can align a patient's bones and knee replacement implants with a degree of accuracy not possible with the naked eye
  • Smaller incisions offer the potential for faster recovery, less bleeding, and less pain for patients

Computers used during orthopaedic surgery offer visual mapping to help doctors make crucial decisions before and throughout the knee replacement operation. The key is to combine the precision and accuracy of computer technology with the surgeon's skill to perform surgery.

Advanced imaging technology provides a computer-generated representation of a patient's knee joint, allowing the surgeon to operate with smaller openings and with more precision. In addition, this technology provides surgeons with greater "vision" during the surgery.

Important Safety Information

The performance of knee replacements depends on age, weight, activity level, and other factors. There are potential risks and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can tell if knee replacement is right for you.
