Overview

The purpose of this research study is to determine the safety and effectiveness of a new treatment for osteoarthritis of the first carpomeetacarpal joint (base of your thumb). The new treatment uses the Cartiva Synthetic Cartilage Implant (Cartiva implant) to replace damaged cartilage in your thumb joint. The most common treatment is called ligament reconstruction tendon interposition (LRTI), where the bone is surgically removed and the joint us stabilized using the surrounding tendons. 

You will need to have the following exam, tests, and procedures to find out if you can be in the study. The exam, tests, and procedures are part of your regular thumb arthritis care and may be done even if you do not join the study. If you have had some of these done recently, they may not need to be repeated. This will be up to your study doctor. 

After surgery you will need to come back for follow up visits. These follow up visits will happen at 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and each year up to 5 years after your hand surgery. The procedures performed during these visits are part of your regular thumb arthritis care.
