ABSTRACT:
A prosthesis for knees and other joints comprises two portions which are disposed side by side and which are at least partially spaced apart from one another. Each portion of the prosthesis includes a pair of spaced apart, relatively inextensible primary components. Disposed between and spaced from the primary components in each portion of the prosthesis is a pivot member. Each pivot member is resiliently secured to the two corresponding primary components of its portion of the prosthesis so as to permit and accommodate relative rotation between the pivot member and the primary components. As a result, the two primary components of each portion of the joint prosthesis can rotate toward and away from one another about an axis that is disposed at least adjacent to and at least approximately parallel to a central axis of the corresponding pivot member. The pivot member and the primary components of each portion of the prosthesis are preferably secured together by one or more bodies of elastomer.
