Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the long-term relief of pain and return to function for patients receiving DeNovo NT for cartilage lesions in the knee. DeNovo NT is a marketed product and has been used in more than 7,500 patients over the last 7 years.
