Brain scans may reveal who will be satisfied after knee surgery
NCT ID NCT07464080
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether brain scans can predict if someone will be satisfied after knee replacement surgery. Up to 1 in 5 patients still have pain or trouble moving after surgery, and doctors can't currently predict who. Researchers will scan the brains of 50 adults before and after surgery to see if brain activity patterns can forecast satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a brain-based test that helps doctors identify patients at risk of dissatisfaction before knee replacement surgery.
- What could go wrong
- This is a small, early-stage study with only 50 participants, so results may not apply to everyone. It is observational and does not test a treatment.
