NCT ID NCT07239999
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two different freezing medications given in the spine for knee replacement surgery. The goal is to see which one lets patients move their legs and leave the hospital faster. 170 adults having outpatient knee replacement will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- spinal anesthetics (chloroprocaine vs mepivacaine)
- What this could lead to
- If one anesthetic works faster, patients could move their legs sooner and go home earlier after knee replacement surgery.
- What could go wrong
- This is a small, early-phase trial comparing two existing drugs, so it is unlikely to lead to a major breakthrough. Results may not apply to all patients.
