Summary

This study tests whether powered prosthetic knees help people with above-knee amputations walk more and feel more confident than standard non-powered knees. Twenty-six adults who already use a mechanical knee will try both types at home for three months each. Researchers will track step counts and balance confidence to see which knee works best in real life.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Powered prosthetic knee (Ossur Power Knee III or Reboocon Intuy Knee)
What this could lead to: If successful, this could help doctors prescribe the right prosthetic knee for each patient, improving mobility and confidence.
What could go wrong: This is a small early-stage study with only 26 participants, so results may not apply to everyone. The devices may not show clear benefits over standard knees.
