Knee surgery painkiller linked to catheter need – new trial seeks safer option
NCT ID NCT07050277
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether skipping intrathecal morphine during knee revision surgery can lower the chance of needing a catheter for urinary retention. Fifty adults having non-infected knee revision will get either morphine or a placebo alongside standard nerve blocks. The goal is to see if pain control stays good while avoiding bladder complications.
