Abstract
Drug-loaded bone cement is used as an application method to prevent and treat prosthesis-related infection. Despite the commercial availability of drug-loaded bone cement, low release rate of drugs from drug-loaded bone cement may result in the emergence of drug-resistant coagulase-negative staphylococci in subsequent deep infection. This work presents a method to control and increase both the drug release rate and total release amounts of drugs for drug-loaded bone cement without losing the mechanical properties of cement. A novel drug-loaded bone cement is also developed by introducing cross-linked poly(methylmethacrylate-acrylic acid sodium salt) particles into bone cement. Capable of increasing the hydrophilicity of the cement and allowing fluids to pass into the cement, the bone cement developed here supplements both the drug release rate and total release amounts of drugs.
