Surgical Applications of Materials Engineered with Antimicrobial Properties

Area of Science:

• Biomedical Engineering
• Infectious Diseases
• Materials Science

Background:

• Surgically implanted devices are susceptible to infection, leading to severe patient outcomes and increased healthcare expenses.
• Implant-associated infections affect nearly all surgical fields, posing a significant clinical challenge.
• Extensive research is underway to mitigate implant infection rates.

Purpose of the Study:

• To review current antimicrobial strategies for preventing implant-associated infections.
• To compile and assess novel approaches modifying implants directly to combat infection.
• To discuss the clinical applications and outcomes of these innovative methods.

Main Methods:

• Review of pre-clinical and clinical investigations on implant infection prevention.
• Analysis of antimicrobial implant coatings, including antifouling materials, antibiotics, metal ions, and antimicrobial peptides.
• Examination of antibacterial nanostructured implant surfaces and antibiotic-releasing implants.

Main Results:

• Antimicrobial strategies directly targeting implants have demonstrated effectiveness in reducing infection rates.
• Various approaches, such as specialized coatings and nanostructured surfaces, are being explored.
• Most advanced implant-specific infection prevention modalities are still in the preclinical or early clinical phases.

Conclusions:

• Direct antimicrobial modification of implants represents a promising frontier in combating implant-associated infections.
• Continued research and clinical translation are crucial for widespread adoption of these effective strategies.
• The development of novel implant-based antimicrobial solutions holds significant potential for improving patient outcomes and reducing healthcare burdens.
