DePuy Orthopaedics·interventional·Posted Jan 29, 2021·Updated Apr 27, 2025

In Brief

A clinical study evaluating Total Knee Replacement for Osteo Arthritis Knee and Osteoarthritis. Completed, enrolled 200 participants across 5 sites.

Detailed 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.
