NCT ID NCT05761015
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a walking program for people with painful hip or knee osteoarthritis. Participants take a nonsteroidal anti-inflammatory drug (NSAID) only before planned walks to reduce pain while avoiding long-term side effects. The program also includes proper footwear, education, and monitoring. The goal is to see if this approach helps people walk more and feel better.
