Could a Two-Word pain question slash opioid use after knee surgery?
NCT ID NCT07065266
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ways of asking about pain after ACL surgery: a simple 'tolerable or intolerable' question versus the standard 0-to-10 scale. The goal is to see if the simpler scale helps patients use fewer opioid painkillers during their two-week recovery. About 130 adults having outpatient ACL reconstruction will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could provide a simple way to reduce opioid use after ACL surgery, potentially lowering addiction risks.
- What could go wrong
- This is a small, single-center study, and the binary scale may not work for all patients or significantly change opioid consumption.

Exclusion Criteria: * Pregnant women * Surgical history of the operated knee * Known allergy to opioid medications * Received extra-routine pain care (as compared with the average ACL patients at the Sports Medicine division) given by the anesthesiologists, such as the postoperative epidural analgesia or the ultra-sound guided femoral nerve block.
