A biocompatible tissue for tendons or ligaments which enables rapid postoperative fixation to bone and early recovery owing to its enhanced biocompatibility and a method for producing such tissue. The biocompatible tissue for tendons or ligaments includes a tendon or ligament tissue substrate and a calcium phosphate compound. The calcium phosphate compound is fixed at least to a surface of the tendon or ligament tissue substrate. The method includes the step of alternately immersing the substrate in a calcium solution and in a phosphate solution to produce and fix the calcium phosphate compound.
L'invention concerne un tissu vital pour un tendon ou un ligament sensé contribuer à la fixation postopératoire rapide aux os et un rétablissement rapide grâce à une biocompatibilité élevée. Un tissu vital pour un tendon ou un ligament comprend notamment une base de tissu de tendon ou de ligament et un composé de phosphate de calcium, ce composé étant fixé à au moins la surface de la base de tissu de tendon ou de ligament. L'invention concerne également un procédé de production d'un tissu vital pour un tendon ou un ligament, qui consiste à immerger la base, en alternance, dans une solution de calcium et dans une solution à base d'acide phosphorique, de manière à former et à fixer le composé de phosphate de calcium.
