Knee surgery pain relief: which additive works best?
NCT ID NCT06470100
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether adding dexamethasone or dexmedetomidine to a standard nerve block (erector spinae plane block) improves pain control after total knee replacement. 90 adults undergoing knee surgery received one of the two drugs or a placebo alongside the nerve block. Researchers measured how long until patients first needed strong painkillers and total opioid use.

Active substance
Dexamethasone and Dexmedetomidine
What this could lead to
If one drug works better, it could lead to longer-lasting pain relief and less need for strong painkillers after knee replacement surgery.
What could go wrong
This is a small, completed Phase 4 study. Results may not apply to all patients, and both drugs have potential side effects like allergic reactions or nerve issues.
