Smith+Nephew Expands CORI◊ Surgical System into Total Hip Arthroplasty with RI.HIP NAVIGATION

Global medical technology business, Smith+Nephew, has announced the expansion of indications on its CORI Surgical System – the industry’s most advanced and efficient1,* handheld robotic solution in total knee arthroplasty1,*,† – to now include total hip arthroplasty (THA). Smith+Nephew’s RI.HIP NAVIGATION – designed to help maximize accuracy and reproducibility by delivering patient-specific component alignment for THA – is now available for use on its CORI System.

Last year, a new study concluded that computer-guided technology for THA significantly reduced the risk of revision2 and increased patient satisfaction2 when using Smith+Nephew implants. The first of its kind study used data from the world’s largest arthroplasty register (National Joint Registry of England, Wales and Northern Ireland) to investigate the effect of computer-guided THA surgery on implant survivorship.2 The data reported on THA surgery performed using Smith+Nephew hip replacement components implanted for osteoarthritis since 2003 and was presented at the 2021 World Arthroplasty Congress. The results demonstrated:

  • A significantly lower revision rate at 10 years with computer-guided (1.06%) vs. conventional THA (3.88%; p=0.005)2
  • A 55% lower risk of revision at 10 years with computer-guided vs. conventional THA (p=0.038)2, and
  • Significantly higher patient satisfaction in the computer-guided group compared to conventional THA (p=0.003)2

“The addition of RI.HIP NAVIGATION on the CORI System further strengthens Smith+Nephew’s Real Intelligence digital ecosystem and underscores our commitment to advancing clinical outcomes in total hip arthroplasty,” said Randy Kilburn, Executive Vice President & General Manager, Reconstruction, Robotics and Digital Surgery for Smith+Nephew. “We look forward to offering the possibility of further improving patient outcomes and satisfaction to a broader surgeon community with the rapidly expanding adoption of our CORI Surgical System.”

Smith+Nephew’s RI.HIP NAVIGATION recently received 510(k) clearance from the United States Food and Drug Administration for use on its CORI Surgical System. Software installations will start immediately for a limited number of hospitals and Ambulatory Surgery Centers (ASCs) in the United States with broad commercial availability later in 2022. It will be introduced in various European and Asia Pacific markets once regulatory authorizations are finalized.
