Computer Assisted Knee Replacement



French surgeons use more and more computer-assisted navigation technology to perform knee replacement. Knee navigation helps ensure better alignment and results for total knee replacement.

One of the most critical aspects of knee replacement surgery is proper positioning of the joint replacement implants. Incorrectly aligned implants can lead to increased wear and loosening of the joint replacement.

In Computer-Assisted Surgery (CAS), a computerised model of the joint is used to ensure correct joint alignment, based on the bone anatomy and the intra-operative ligament situation. By tracking surgical instruments and components in relation to patient anatomy, Total knee navigation software is proven to improve long-leg alignment and functionality.

  • Proven clinical benefit

  • Superior soft-tissue management

  • Truly open platform enhances implant workflow and flexibility

Proven clinical benefit

Several independent studies over the years have shown that using computer navigation for knee replacement surgery reduces the number of outliers and improves overall alignment, leading to better performance and longer life of the implants.

  • Fewer outliers, better varus/valgus alignment

  • Less risk of fat embolisms

  • Less blood loss

  • Fewer complications for TKR

Superior soft tissue management for TKR

Today's active patients are demanding a natural-feeling knee, so attention to soft tissue is increasingly important in total knee arthroplasty. Applications have multiple ways to assess and quantify the soft tissue envelope, including gap balancing and balance information through the entire range of motion.

  • Multiple workflows

  • Balancing in extension and flexion

  • Gap balancing

  • Range of motion analysis
