NCT ID NCT03391323
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared four different knee replacement devices in 218 adults with knee arthritis to see which one patients 'forget' about most after surgery. The main goal was to measure how natural the joint feels using the Forgotten Joint Score. Results could help surgeons choose the best implant for a more natural-feeling knee.
