NCT ID NCT06211504
First seen Oct 31, 2025 · Last updated Jun 19, 2026 · Updated 35 times
Summary
This study tests whether adding a small implant in the sinus tarsi (a space in the foot) to standard flatfoot surgery helps correct the deformity better than surgery alone. Researchers will enroll 130 adults with flexible flatfoot who haven't improved with non-surgical treatments. Participants will be randomly assigned to receive either standard surgery plus the implant or standard surgery alone, and will be followed for 2 years with X-rays and questionnaires.
