NCT ID NCT06933706
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking losartan for 30 days after multi-ligament knee surgery helps people regain motion, strength, and return to work or sport. About 90 adults with severe knee injuries will be randomly assigned to receive losartan or a placebo. The goal is to reduce inflammation and improve outcomes in the first year after surgery.
