Summary
This study tests whether a powered prosthetic knee (Ossur Power Knee) helps people with above-knee amputations walk better than a standard microprocessor knee. Twenty adults aged 45-75 who have used a prosthetic leg for at least a year will try both knees for a month each. Researchers will measure walking speed, energy use, and how easily they stand up from a chair.

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 the powered knee works better, it could help people with leg 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 offer clear benefits over the standard knee.
As listed by the trial registrant
The condition terms exactly as the trial's registrant entered them.
