Summary

This study compares a powered prosthetic knee (Ossur Power Knee) to a standard microprocessor knee in 20 people with above-knee amputations. Participants will use each knee for a month, then researchers measure walking speed, energy use, and sit-to-stand movements. The goal is to see if the powered knee improves mobility and whether men and women benefit differently.

What this could mean

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

Active substance: Ossur Power Knee (powered prosthetic knee joint)
What this could lead to: If it works, this could show that a powered knee helps people with above-knee amputations walk more easily and with less effort.
What could go wrong: This is a small, early-stage study with only 20 participants, so results may not apply to everyone. The powered knee may not provide meaningful benefits over standard options.
