Needles vs. pills: can acupuncture cut opioid use after hip surgery?
NCT ID NCT05384860
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether giving acupuncture during hip replacement surgery helps patients use fewer opioids and recover faster. 484 adults having hip replacement were split into two groups: one received ear acupuncture with mild electrical stimulation while sedated, and the other had standard surgery without acupuncture. The main goal was to see if more patients in the acupuncture group kept their opioid use low for 30 days after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- auricular acupuncture with low-frequency electrostimulation
- What this could lead to
- If it works, this could offer a low-cost, low-risk way to reduce opioid use and speed recovery after hip replacement surgery.
- What could go wrong
- This is a completed study, but results are not yet widely confirmed. Acupuncture's effect on opioid use may be small or not generalizable to all patients.
