Scientists compare three knee implant designs to see which moves most naturally
NCT ID NCT05107414
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how three types of Journey II knee replacements (BCS, CR, and XR) move inside the body during activities like bending. Researchers will use video and sound recordings to measure joint motion in people who had knee replacement surgery at least six months ago. The goal is to understand which design allows for the most natural movement, which could help guide future implant choices.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Smith & Nephew Journey II total knee arthroplasty (BCS, CR, or XR model)
What this could lead to
If successful, this study could help surgeons choose which knee replacement design offers the best motion and function for patients.
What could go wrong
This is an observational study with no treatment being tested, so it cannot prove that one knee design is better than another. Results may not apply to all patients.
