Robotic knee surgery put to the test in 252-Patient study
NCT ID NCT04338893
First seen Nov 01, 2025
Summary
This study looked at whether using a robotic system (ROSA) during knee replacement surgery leads to more accurate implant placement compared to traditional methods. It included 252 adults with knee pain, arthritis, or deformities who were already scheduled for knee replacement. Researchers measured alignment accuracy with CT scans and also tracked surgery time and patient-reported outcomes.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ROSA Knee System (robotic surgical device) used with Persona, NexGen, or Vanguard total knee implants
What this could lead to
If successful, this could show that robotic-assisted knee replacement leads to more accurate implant placement and better patient outcomes.
What could go wrong
This is a completed post-market study, not a randomized trial, so results may not prove superiority. Robotic surgery may not improve pain or function for all patients.
