Zimmer robotic surgery system found to improve accuracy

A newly developed robotic surgery system has been found to improve surgeon accuracy in knee operations.

The Zimmer Biomet ROSA Knee System provides surgeons “an intuitive inference displaying planned resections throughout cuts and a validation tool to verify cuts’ accuracy in real-time”, says the company.

Zimmer Biomet is a Warsaw, Indiana-based company which designs and manufactures a range of musculoskeletal healthcare products.

The company’s new robotic knee surgery system was the subject of a study published in the Journal of Arthroplasty.

The study concluded that the Zimmer Bionet Rosa knee system can increase surgeon accuracy in bone cuts by:

  • Providing higher levels of precision in regard to targeted angles and resection thickness compared to navigation;
  • Accuracy better than 1 degree (angular) and 1 mm (bone resection) is achieved and reproducible; and
  • Collaborative robotic assisted surgery is efficient, incredibly accurate, and adapts robotics to a surgeon’s technique.

The authors of the report concluded: “Despite the fact that this study was funded by Zimmer Biomet and only used Zimmer Biomet implants, robot, and navigation tools, the results of our in vitro study demonstrated that surgeons using this new surgical robot in total knee arthroplasty can perform highly accurate bone cuts to achieve the planned angles and resection thickness as measured using conventional navigation.”
