Massive joint replacement registry aims to improve surgery quality
NCT ID NCT01909375
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This registry collects information from over 500,000 people in the US who have had hip or knee replacement surgery. The goal is to track their health and quality of life over time to find ways to improve care. It is a data-gathering effort, not a test of a new drug or device.
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 registry could help identify best practices and improve outcomes for people undergoing hip or knee replacement surgery.
- What could go wrong
- This is an observational registry, not a treatment trial. It collects data but does not test a new therapy, so direct patient benefits may take years to emerge.
