Evaluate the Continued Safety and Performance of the Foot and Ankle Products

This study is a registry tracking the safety and long-term performance of Arthrex foot and ankle surgical products, including various implants and devices used in ankle fusion, big toe joint replacement, and other foot and ankle procedures. Registries like this are important for gathering real-world data on how medical devices perform outside of tightly controlled clinical trials. Participants will be followed through their normal clinical care, completing questionnaires about their symptoms and function at various time points after surgery. The goal is to build a comprehensive dataset that helps surgeons and device manufacturers improve future care. You may be eligible if... - You are 18 years of age or older (or 2–17 years for a specific product called ProStop) - You need surgery using one of the Arthrex foot and ankle products covered by the registry - You are able to complete questionnaires and return for follow-up visits You may NOT be eligible if... - You have insufficient bone quality or an active infection in the surgical area - You are currently pregnant - You are a prisoner or other vulnerable individual - You are already receiving workers' compensation benefits for the same condition - You have another planned surgery on the same or opposite lower limb during the study period Talk to your doctor to see if this trial is right for you.
