Summary

This study will test whether a microprocessor-controlled knee (MPK) helps 20 veterans with above-knee amputation walk better and feel more confident compared to a standard mechanical knee. Participants will first use their regular knee, then switch to the smart knee for two months. Researchers will measure walking speed, falls, and mobility confidence to see if the high-tech knee makes a real difference.

What this could mean

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

Active substance: College Park ICON microprocessor-controlled prosthetic knee
What this could lead to: If it works, this could show that a smart knee helps lower-functioning veterans walk better and feel more confident, potentially leading to wider access to advanced prosthetics.
What could go wrong: This is a very small early study with only 20 veterans, so results may not apply to everyone. The smart knee might not improve mobility enough to justify its higher cost or complexity.
