Clinical Trial Summary

The purpose of this study is to evaluate both short and long term clinical performance and safety of the commercially available U2 Knee™ System.


Description:

This is a prospective, single arm, multi-center, post-approval study designed to evaluate the short and long term clinical performance and safety in subjects receiving primary total knee arthroplasty (TKA) with the U2 Knee™ System. The study will enroll up to 200 subjects with scheduled pre-discharge, 6-week, 3- and 6-month and up to 5-year annual follow-up visits. Study outcomes will be analyzed and published when 1.) all enrolled and implanted subjects complete their 6-week follow up, 2.) all implanted subjects complete their 2-year follow up, 3.) at the conclusion of the study. The study will follow GCP guidelines and will be registered on clinicaltrials.gov.
