Poly (lactic-co-glycolic acid) (PLGA) is a star biodegradable polymer widely studied and applied in the biomedical field. Improving the acidic microenvironment caused by its degradation products and regulating its degradation behavior are still urgent scientific and technological problems to be solved. In this study, to regulate the degradation behaviors of PLGA and improve its bioactivity, hydroxyapatite (HA) and magnesium oxide (MgO) were incorporated into PLGA substrate in different proportions and a series of 3D-printing PLGA/HA/MgO (PHM) composite porous scaffolds were prepared. Then the physicochemical properties, degradation behaviors, in vitro and in vivo biological performance of fabricated scaffolds were systematically studied.…
