A 3D-printed, high-strength, and drug-eluting composite for the treatment of periprosthetic joint infections by Bijan Abar, Bijan Abar, Harrison Goonewardene, Richard Sheng, Mitchell H. Negus, Nicholas B. Allen, Cambre N. Kelly, Natasha C. Stinson, Matthew L. Becker, Joshua T. Thaden, Samuel B. Adams, Ken Gall

“…However, antibiotic elution was influenced by the type and concentration of the antibiotic in the composite. In contrast, the thermoplastic properties of PMMA led to a decrease in compressive properties with the addition of antibiotics, but PMMA was able to elute relatively more antibiotics.DiscussionThis study described a novel method to 3D print load bearing materials that can release antibiotics over 30 days. …”
