Which knee implant lasts longer? a Head-to-Head test
NCT ID NCT02766231
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This study follows people with knee osteoarthritis who receive one of two total knee replacement designs: a cruciate-retaining (CR) or a posterior-stabilized (PS) implant. The goal is to compare how well each design relieves pain, restores function, and holds up over time. Researchers will track clinical scores, X-ray results, and patient-reported outcomes, as well as any complications, to see if one implant offers better long-term results.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Two types of total knee replacement prostheses: a cruciate-retaining (CR) design and a posterior-stabilized (PS) design
- What this could lead to
- If successful, this could help surgeons choose the best knee implant design for individual patients, improving long-term outcomes and satisfaction after knee replacement surgery.
- What could go wrong
- This is an observational post-market study, not a randomized controlled trial, so results may be influenced by patient selection. Outcomes depend on surgical technique and patient factors, and the study does not guarantee that one implant is superior.
