Summary

This study tests whether cannabidiol (CBD) can lower the need for opioid painkillers after knee replacement surgery. 380 adults with knee osteoarthritis will take CBD or a placebo before and after surgery. Researchers will measure total opioid use and pain over 28 days to see if CBD helps reduce reliance on opioids.

Cannabidiol (CBD) oral solution

What this could lead to

If it works, this could offer a way to reduce opioid painkiller use after knee replacement, lowering addiction risk and side effects.

What could go wrong

This is an early phase 2 trial, so results may not confirm benefit. CBD may cause side effects like drowsiness or liver issues, and the opioid-sparing effect might be small or absent.
