Various embodiments disclosed relate to antioxidant-stabilized materials including ultra high molecular weight polyethylene (UHMWPE), methods of making the same, and medical implants including the same. In various embodiments, the present invention provides a method of adding antioxidant to UHMWPE. The method includes obtaining or providing a porous solid material including UHMWPE. The method includes coating the porous solid material with a liquid composition including at least one antioxidant such that at least some of the liquid composition enters void space of the porous solid material, to provide an antioxidant-infused solid material. The method also includes melt-consolidating the antioxidant-infused solid material, to provide a melt-consolidated material. |
