Like prosthetic feet, the type of prosthetic knee selected for each individual is determined based on their intended activity level and the type of terrain that they will be traversing. These knee units can be similarly grouped into categories associated with the four main Impact Levels.

Children, Youth and Adults have access to many of the same classifications of knee units, built to suit their weight range and activity levels. Contact us at I.A.S to inquire about various prosthetic knee options.
