Which anesthesia gets you home faster after joint replacement?
NCT ID NCT07834242
First seen Sep 22, 2026 · Last updated Sep 23, 2026 · Updated 1 time
Summary
Researchers compare spinal anesthesia with general anesthesia in adults scheduled for elective hip or knee replacement. The trial enrolls about 3,000 participants across multiple hospitals. It measures how many days within the first month after surgery participants spend alive and out of the hospital, along with major complications, recovery quality, and patient satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Spinal anesthesia versus general anesthesia
- What this could lead to
- If one approach proves better, it could guide anesthesia choices for hundreds of thousands of hip and knee replacement surgeries each year, potentially improving recovery and reducing complications.
- What could go wrong
- Both anesthesia methods are already widely used and considered safe, so differences may be small. The trial may not find a clear winner, and results might not apply to patients with different health profiles or surgical settings.
