Biocompatible Biodegradable Composite Materials in the Biopolymer–Calcium Phosphate System for Replacing Osteochondral Defects

This work is aimed at developing new materials with adjustable composition, microstructure, and properties for replacing osteochondral defects. Features of the interaction of components in the biopolymers–calcium phosphates systems were revealed, processes of the formation of framework structures of the composite material were determined, and their mechanical, chemical, and structural characteristics were examined. Experiments were carried out to simulate the behavior of matrices and changes in their properties during exposure to model body fluids.
