Knee replacement pain relief: which catheter placement stays put?
NCT ID NCT07681622
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study compares two techniques for inserting a thin tube (catheter) that delivers numbing medicine to the thigh after knee replacement surgery. The goal is to see which method keeps the catheter in place better, since movement can cause it to slip and reduce pain relief. Researchers will also check pain levels and painkiller use on the first day after surgery. The trial involves 48 adults undergoing knee replacement.

Active substance
continuous adductor canal block catheter
What this could lead to
If one technique proves more stable, it could improve pain control and reduce opioid use after knee replacement surgery.
What could go wrong
This is a small, early-stage comparison study (48 participants) that may not show a clear difference between techniques. Results may not apply to all patients or surgical settings.
