Summary

This study tests whether an extended-release steroid injection (Zilretta) given during knee meniscus surgery can reduce pain and inflammation in people with osteoarthritis. 150 adults aged 40 and older are enrolled. Researchers will measure knee pain scores and inflammatory markers over 12 months to see if the injection improves outcomes.
