COMPOSITE SUPPORT INSERTS FOR THE TOTAL ARTICLE OF THE KNEE.

摘要

A modular composite support assembly (100) for a knee joint, comprising: a metal tibial element (110) and a composite support insert structure (120) fixed to the metal tibial element, in which said structure of the Composite support insert includes a molded polymeric support component (140), interlocked with a metal endoskeleton component (130), wherein said metal endoskeleton component is interlocked with said metal tibial element, and in which said Polymeric support component is configured to operatively engage a femoral component, and characterized in that said polymeric support insert is interlocked with said metal endoskeleton component, through an interlocking structure (150, 160), including the surfaces of wedge-shaped coupling, at the endoskeleton / polymer junction, in order to mechanically block the two parts by the action of the contraction of the polymer around the endoskeleton at the moment of molding.
