NCT ID NCT07237711
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a gel called Sensovisc, injected into the knee joint to reduce pain and improve movement in people with knee osteoarthritis. About 75 adults with moderate knee arthritis will receive the gel and be followed for 6 months. The goal is to see if the gel safely eases pain during rest, activity, and sleep.
