Intramuscular implantation test of 20w showed that porous composite scaffolds of surface grafted g-HAP/PLGA and ungrafted n-HAP/PLGA presented slower degradation and higher mineralization compared to that of pure PLGA. Compared with n-HAP/PLGA, g-HAP/PLGA showed an improved absorption and biomineralization because of its improved distribution of g-HAP nanoparticles in PLGA matrix.
