High Degree of Accuracy of a Novel Image-free Handheld Robot for Unicondylar Knee Arthroplasty in a Cadaveric Study3
SUMMARY STATEMENT: This cadaveric study investigates the implant accuracy of a novel image-free robotic-assisted surgery device for unicondylar knee arthroplasty. The method compared the planned and final implant placement in twenty-five cadaveric specimens undergoing medial compartmental UKA with the NAVIO System (Blue Belt Technologies, Plymouth, MN). A quantitative analysis was performed to determine the translational, angular and rotational differences between the planned and achieved positions of the implant components.
RESULTS: Results of this cadaveric study demonstrate implant position using the NAVIO system were within the expected target to plan with low rotational, angular and translational errors. Results are comparable with those published from clinical investigations of other semi-autonomous robotic orthopaedic devices.
