Summary

This trial will assess whether adding CBD to usual care before and after surgery can reduce the rate of persistent post-surgical pain after total knee replacement.

Who is the study for?
This trial is for adults over 18 who are having knee replacement surgery and can understand English. They must be able to follow the study's steps and not have other chronic pain conditions, severe heart/lung disease, substance use disorders, or allergies to cannabis. Pregnant or breastfeeding individuals cannot participate.
What is being tested?
The study tests if a CBD dominant oil (MPL-001) reduces long-term pain after knee surgery compared to a placebo oil. Participants will be randomly assigned to one of these two options and monitored for six months to see how well they do with their usual care plus the test product.
What are the potential side effects?
While specific side effects aren't listed here, CBD products may cause tiredness, changes in appetite or weight, diarrhea, and sometimes mood changes. THC can lead to feeling 'high', but since it's much less than CBD in this mix, that effect might be minimal.
