Clinical Investigation (Beta) of a New Developed Prosthetic Knee

Investigation on Performance of a New Developed Prosthetic Knee

The aim of this investigation is to evaluate the efficacy of the investigational device regarding performance improvements and satisfaction in descending activities for moderate to high active prosthesis users within the intended population for the investigational device. Additionally, the overall satisfaction for activities of daily living will be evaluated after a certain time of use (4 weeks home use).
