Effects of Cannabidiol (CBD) Oral Solution in Patients Undergoing Bilateral Total Knee Arthroplasty: a Randomized, Controlled, Parallel, Triple Blind, Pilot Study

Hospital for Special Surgery, New York·interventional·Posted Feb 11, 2021·Updated May 26, 2026

In Brief

A Phase 4 clinical trial evaluating cannabidiol and Ora-sweet SF for Pain, Postoperative and 2 related conditions. Completed, enrolled 37 participants across 1 site.

Detailed Summary

In light of the opioid epidemic and evidence suggesting that cannabis may be opioid-sparing, we are in a unique position to conduct a novel, high-impact study that would set the stage for future RCTs examining the effects of a nonintoxicating and nonaddictive cannabinoid in an orthopedic patient population. Epidiolex®, an oral cannabidiol (CBD) solution, is the first ever cannabis-derived medication to be approved by the Food \& Drug Administration. Our aim is to conduct a pilot study using a placebo oral solution, 400mg and 800mg Epidiolex® to gather data on its effects on patients undergoing bilateral total knee arthroplasty (BTKA). We will be estimating whether Epidiolex® is associated with minimal opioid use and adequate analgesia. We will also assess its tolerability, pharmacokinetics, and effects on inflammatory markers in the perioperative setting.
