Study Summary

The purpose of this post-market research study is to gather clinical and radiographic (X-ray) information about total knee replacement surgeries completed with the VELYS Robotic-Assisted Solution and with standard manual instrumentation. The VELYS Robotic-Assisted Solution helps the surgeon to plan bone cuts and then accurately achieve the planned cuts during the total knee replacement surgery. The study aims to compare how well the VELYS Robotic-Assisted system enables the surgeon to position the implants exactly as planned compared to manual instrumentation.

Primary Outcome

The primary objective of this clinical investigation is to evaluate whether the accuracy to plan of the long leg alignment achieved with VELYS Robotic-Assisted Solution is non-inferior to the accuracy to plan of the long leg alignment achieved with the manual ATTUNE Intuition instrumentation. This will be assessed by measuring the Hip-Knee-Ankle angle (HKA) on long-leg X-rays taken at 12 weeks and comparing to the planned HKA. A smaller number represents improved accuracy and a better outcome.
