Smith & Nephew, the global medical technology business, has announced completion of the world’s first robotics-assisted bi-cruciate retaining total knee replacement procedures. 
 
The NAVIO robotics-assisted surgical system aids in implanting the JOURNEY II XR (bi-cruciate retaining total knee system) which is one of the only total knee designs allowing retention of the ACL, and is designed to improve patient satisfaction.¹
 
With this launch, NAVIO now offers both partial and total knee options that include the first and only robotics-assisted bi-cruciate retaining knee procedure, commercially available today.
 
Drs. Vivek Neginhal (WV), David Rovinsky(HI), and David Fabi (CA) recently performed the first cases. “I believe that the NAVIO is able to provide critical elements of success for the JOURNEY II XR, such as accuracy of tibia component placement and a streamlined surgical technique.” Dr. Neginhal further commented, “I was amazed at how fluid the knee motion was on the first postop day. My patients have expressed great satisfaction so far. I believe that NAVIO’s accuracy and flexibility of use combined with JOURNEY II XR’s retention of the patient’s cruciate ligaments and physiological design will truly increase patients’ function and satisfaction.”
 
The NAVIO is a next generation handheld robotics platform designed to aid surgeons with implant alignment, ligament balancing and bone preparation—key factors that can drive implant survivorship.^2,3 The small footprint of NAVIO allows for set up and portability. Furthermore, the NAVIO robotics-assisted system does not require a preoperative image, such as a CT scan. This allows patients to receive the benefits of robotics-assistance without the extra steps, costs, and radiation associated with additional preoperative imaging.⁴
 
“The JOURNEY II XR bi-cruciate retaining knee has the potential to deliver the best possible outcome for the surgeon and patient through the preservation of important anatomical structures such as the ACL. The NAVIO robotics-assistedsurgical system enables accurate tibial implant placement to deliver a more reproducible surgical technique. We are proud to be the only company to offer the unique combination of NAVIO robotics-assistance and the JOURNEY II XR Knee System,” said Mike Donoghue, senior vice president of global marketing, Orthopaedics at Smith & Nephew.
