NCT ID NCT02839850
First seen Jun 26, 2026 · Last updated Jul 07, 2026 · Updated 3 times
Summary
This study is testing a new type of knee replacement implant that does not use cement to hold it in place. The implant, called ATTUNE Cementless Rotating Platform, is designed for people with osteoarthritis. Researchers will follow 540 patients for two years to see if their ability to perform daily activities improves after surgery. The study uses patient questionnaires to measure outcomes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- ATTUNE cementless rotating platform total knee arthroplasty (a knee implant device)
- What this could lead to
- If successful, this could provide a durable, cement-free knee replacement option that improves mobility and reduces pain for people with osteoarthritis.
- What could go wrong
- This is an observational device study, not a randomized trial, so results may not prove superiority over existing implants. Risks include implant failure, infection, or need for revision surgery.
