Summary

This trial tests whether giving far fewer opioid pills after hip arthroscopy, combined with gabapentin and extra-strength Tylenol, can control pain as well as the standard 30-pill opioid prescription. About 170 adults undergoing their first hip arthroscopy will be randomly assigned to either the reduced or standard regimen. The study tracks pain scores, how many opioids are actually taken, and whether unused pills are properly disposed of.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A reduced opioid regimen combining hydrocodone-acetaminophen (Norco), gabapentin, and extra-strength acetaminophen (Tylenol)
What this could lead to
If successful, this could point to a safer way to manage post-surgical pain with fewer opioid pills, potentially reducing the risk of opioid dependence.
What could go wrong
The trial is relatively small and early, and pain relief might be less effective with fewer opioids, leading to higher pain scores or the need for additional medication.
