Understanding joint replacement technologies
available in Southern Utah

By collecting patient-specific information, boundaries are established for the hand piece so the surgeon can remove the damaged surfaces of the knee, balance the joint, and position the implant with greater precision.

The robotics and AI enhance control of the your unique anatomy to improve outcomes including proper size, implant positioning, soft-tissue balance, and lower limb alignment,.

Key Comparisons

  • Robotic-assisted total knee arthroplasty (RA-TKA) delivers improved consistency for precision and accuracy in the placement, alignment, balancing,  and restoration of function
  • Greater cost savings in a 90-day episode of care (typical) compared to knee replacement done without robotic or computer assisted navigation systems 
  • Meets the demands of patients, insurers, employer- and union-sponsored health plans for better quality of care, lower costs and “value-based” options
  • Insurers and patients demand higher-quality, longer service-life implants and lower complications and fewer revisions (“do overs”)
  • Recent published, unbiased literature (April 2021) indicates “robotic-assisted (RA-TKA) outcomes are leading the way forward

9 INTERESTING FACTS ABOUT ROBOTIC-ASSISTED KNEE REPLACEMENT

  1. With OmniBot, only “total” knee replacements are possible, even if the patient only requires a “partial” or “uni-compartmental” implant. 
  2. With Mako and OmniBot, a pre-operative CT scan is required, equal to about 10x the radiation exposure of that of a flight across the USA
  3. Oxinium (oxidized zirconium) implants, available exclusively through Smith & Nephew using the NAVIO and CORI systems, improves hardness, lubricity, (the reduction of friction of the parts that touch each other during normal knee motion), and abrasion resistance (the ability of materials and structures to withstand the wearing down or rubbing away of the material by means of friction). It has an FDA-rated 30 year service life.
  4. Oxinium is a ceramicized metal bearing surface that reduces risk of fracture. The surface is chemically transformed, it is not a “coating”. 
  5. With robotic joint replacements, research indicates reduced postoperative soft tissue swelling in the robotic cohort may limit local inflammatory response resulting in decreased pain and postoperative swelling. It may also result in quicker increased postoperative range of motion 
  6. Research indicates that robotic-assisted knee replacement patients tend to have have less postoperative pain, and tend to need less pain medication. 
  7. Research indicates that robotic-assisted knee replacement patients tend to require reduced physical therapy duration 
  8. Robotic-assisted technology actively controls or restrains the surgeon from making movements outside the area where bone should be removed
  9. With the Robotic-assisted technology, the robotic physically assists the surgeon in executing the preoperative plan with a high level of precision and accuracy by preventing accidental slips and movements outside the planned cutting zones when removing bone prior to placing the implant.
