Robert P. Runner, MD presented a study at the 2019 AAHKS Annual Meeting that examined patient use of tetrahydrocannabinol (THC) and cannabidiol (CBD) products in the period before, during and after total knee replacement surgery. Dr. Runner discusses what he found in users versus non-users and what physicians should be aware of in the preliminary findings of his study. Topics include:

* What is THC/CBD?
* What types of products do patients use?
* Analysis – were there benefits?
* Patients will be using these more and more. What’s best for them? What’s next?
