Abstract

This work presents the results of a study to determine if circular gears are comparable to noncircular gears (in terms of tibial position accuracy during gait) in a transfemoral prosthetic knee. In this study, the authors’ design method for gear-based transfemoral prosthetic knees was utilized using clinical knee motion data during gait from several published sources. The data from these sources reflect knee motion distinctions due to gender, age, nationality, body mass, gait speed and knee condition. Unlike noncircular gears, which are custom-made, circular gears can offer advantages in manufacturing cost and design simplicity since it is a standard component. However, to justify the use of circular gears in a prosthetic knee design, it must be determined if the design can consistently exhibit tibial position accuracy that is at least comparable to noncircular gears when empirical knee motion data that reflect a range of differing human physical characteristics are considered.
