Smart knees may help amputees stay steady and active

This study looks at whether a prosthetic knee with a built-in computer (microprocessor-controlled) can help people with above-knee amputations have fewer fall-related problems, walk faster, and feel better overall. About 100 adults who already use a basic prosthetic knee will either keep their current knee or get a smart knee. Researchers will track falls, confidence, and quality of life over time.
