Custom knee surgery tools aim for better fit and faster recovery
NCT ID NCT01818401
First seen Jul 17, 2026 ยท Last updated Jul 17, 2026
Summary
This trial compares standard knee replacement surgery to surgery using custom cutting blocks designed from each patient's anatomy. The goal is to see if these personalized tools lead to better knee function, less bleeding, shorter surgery time, and lower overall costs. About 95 people with advanced knee osteoarthritis are taking part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- custom cutting blocks (MyKnee LBS) used during total knee replacement surgery
- What this could lead to
- If successful, custom cutting blocks could make knee replacement surgery more precise, reduce complications, and lower healthcare costs.
- What could go wrong
- This is a small, early-stage trial, so results may not apply to all patients. Custom blocks add cost and preparation time, and may not improve outcomes enough to justify their use.
