THC/CBD combinations showed modest opioid-sparing potential after orthopedic surgery, but CBD alone had mixed results
A scoping review of 14 studies found THC/CBD combinations showed modest potential for reducing opioid use after orthopedic surgery with neutral safety profiles, while CBD-only interventions had inconsistent results.
Quick Facts
What This Study Found
CBD-only interventions showed mixed results for post-orthopedic surgical pain. THC/CBD combinations demonstrated modest potential for opioid-sparing effects with neutral safety profiles. One THC-only study reported increased opioid use and longer hospital stays, though confounders were present.
Key Numbers
14 experimental studies included. Three categories: CBD-only (mixed results), THC-only (1 study, worse outcomes), THC/CBD combination (modest opioid-sparing). Overall evidence limited by heterogeneous study designs.
How They Did This
Scoping review of experimental studies published from 2014 to 2025 investigating cannabis or CBD for postoperative orthopedic pain management. Fourteen studies met inclusion criteria, categorized by cannabinoid composition (CBD only, THC only, or THC/CBD combination).
Why This Research Matters
Opioid dependence after orthopedic surgery is a major clinical problem. Understanding which cannabinoid formulations might help reduce opioid use postoperatively is crucial, especially given the heterogeneity in available evidence.
The Bigger Picture
The finding that THC/CBD combinations may be more promising than CBD alone aligns with the broader trend in cannabinoid research suggesting that multi-cannabinoid approaches outperform single-compound interventions.
What This Study Doesn't Tell Us
Only 14 studies, with heterogeneous designs, formulations, dosing, and patient populations. Scoping review methodology does not assess study quality. Most studies were small. Results cannot be generalized across orthopedic procedure types.
Questions This Raises
- ?What THC:CBD ratios are most effective for postoperative pain?
- ?Should cannabinoids be started preoperatively or postoperatively?
- ?Would standardized study designs resolve the inconsistency in CBD-only results?

What do these levels mean? →Frequently Asked Questions
Can cannabis reduce opioid use after orthopedic surgery?
THC/CBD combinations showed modest potential for reducing opioid use with acceptable safety, but CBD alone had inconsistent results. More standardized research is needed.
Is CBD effective for postoperative pain?
Results were mixed. CBD-only interventions did not consistently reduce pain or opioid use after orthopedic surgery, though the studies varied widely in design and dosing.
