Knee replacement pain relief showdown: which numbing cocktail wins?
NCT ID NCT07509866
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests three different numbing medicine combinations for pain after total knee replacement. 90 adults having knee surgery will get one of three options: a long-acting numbing drug, or a standard numbing drug plus one of two additives. The goal is to see which approach reduces the need for opioid painkillers and helps people get moving sooner.

- Active substance
- Liposomal bupivacaine, ropivacaine with dexamethasone, ropivacaine with dexmedetomidine
- What this could lead to
- If successful, this could identify the most effective numbing approach for knee replacement surgery, leading to less pain, less opioid use, and faster recovery.
- What could go wrong
- This is a small, early-stage trial with only 90 participants, so results may not apply to everyone. The different numbing methods may work similarly, and unexpected side effects are possible.
