Knee replacement showdown: cemented vs. uncemented implants under scrutiny
NCT ID NCT02525601
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two versions of the Triathlon total knee prosthesis—one fixed with bone cement and one without—in 60 people with knee osteoarthritis. Researchers will use special X-ray techniques to see how well each implant stays in place over time, and also track patients' pain, function, and satisfaction. The goal is to find out which method leads to better long-term outcomes and fewer complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Triathlon total knee prosthesis (cemented and uncemented versions)
- What this could lead to
- If successful, this could help determine which type of knee implant (cemented or uncemented) provides better long-term stability and function for patients with osteoarthritis.
- What could go wrong
- This is a small, early-stage study with only 60 participants, so results may not apply to everyone. The main risk is that one implant type may loosen or fail over time, requiring revision surgery.
