Robot or surgeon? knee replacement study checks metal in your blood
NCT ID NCT06447922
First seen Jun 27, 2026 · Last updated Jul 14, 2026 · Updated 2 times
Summary
This study looks at metal levels (like cobalt and chromium) in the blood of 60 adults after knee replacement surgery. Some had robotic-assisted surgery, others had the traditional method. The goal is to see if one approach leads to higher metal levels, which could affect safety. Participants must not have had prior joint replacements or metal implants.
