New ankle implant tracked for 5 years to see if it holds up
NCT ID NCT04944576
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study follows about 80 adults who receive the EasyMove total ankle prosthesis for severe ankle arthritis caused by injury, wear-and-tear, or rheumatoid arthritis. Researchers will monitor how often the implant loosens and needs revision, as well as pain, mobility, and function over five years. The goal is to see how well the device performs in everyday medical practice.
