Smith+Nephew shared results from a new study demonstrated computer-guided technology for total hip arthroplasty (THA)—such as Smith+Nephew's RI.HIP NAVIGATION—significantly reduces revision risk and increases satisfaction when using Smith+Nephew implants.
The study is the first of its kind using 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.1 The data reported on THA surgery using Smith+Nephew hip replacement components implanted for osteoarthritis since 2003. Presented at the 2021 World Arthroplasty Congress (WAC), the results demonstrated:
"Computer-guided technology for total hip arthroplasty has been around for more than twenty years and this study confirms that it greatly improves a patient's chance for long-term success and their overall satisfaction," Prof. Edward T. Davis FRCS of The Royal Orthopaedic Hospital NHS Foundation Trust told the press. "RI.HIP NAVIGATION helps me take control of individual patient pelvic tilt, leg length and offset measurement while assisting with cup placement by giving a predicted view of the post-op AP X-ray in surgery. This gives me supreme confidence that I'm performing the most accurate THA procedure for my patient and ensuring the best possible result."
RI.HIP NAVIGATION technology helps maximize accuracy and reproducibility with patient-specific component alignment—a critical factor when assessing individual THA cases. Using this technology with Smith+Nephew's POLAR3 Primary Total Hip System—comprised of POLARSTEM, OXINIUM and R3 acetabular components—could take THA to the next level of performance.
"Conventional total hip arthroplasty is considered to be a very successful procedure, however there is always room for improvement," said Randy Kilburn, Senior Vice President of Commercial Marketing, Orthopaedics for Smith+Nephew. "RI.HIP NAVIGATION combined with our best-in-class POLAR® THA construct may considerably improve implant survivorship and help patients return to living their Life Unlimited."

Presented at the 2021 World Arthroplasty Congress (WAC), the results demonstrated:
- Significantly lower revision rate at 10 years with computer-guided (1.06 percent) vs. conventional THA (3.88 percent; p=0.005)
- 55 percent lower risk of revision at 10 years with computer-guided vs. conventional THA (p=0.038)
- Patient satisfaction was significantly higher in the computer-guided group compared to conventional THA (p=0.003)
