Title (EN) CARTILAGE REPAIR IMPLANT
(FR) IMPLANT POUR REPARATION DE CARTILAGE
Abstract:
(EN) A cartilage repair implant comprises a layer of a resilient substitute cartilage material such as a hydrogel, and an anchor layer to which the layer of resilient substitute cartilage material is bound to form a composite structure. The anchor layer comprises an acrylate based polymer and contains calcium ions which can be leached from the layer to facilitate ingrowth of bone tissue into the anchor layer.
(FR) L'invention concerne un implant pour réparation de cartilage comprenant une couche de matériau de cartilage de substitution résiliante, telle qu'un hydrogel, et une couche d'ancrage à laquelle ladite couche de matériau de cartilage de substitution résiliante est liée afin de former une structure composite. La couche d'ancrage comprend un polymère à base d'acrylate et contient des ions calciques qui peuvent être extraits par lixiviation de la couche afin de faciliter l'interposition d'un tissu osseux dans la couche d'ancrage.
