Summary

This study is testing a device called the CORI™ KNEE TENSIONER, which helps surgeons balance the knee during total knee replacement surgery. Fifty adults who need a knee replacement will have the surgery using this device, and their recovery and quality of life will be tracked for one year. The goal is to see if the device makes the surgery more precise and improves patient outcomes.
