Current Strategies in Developing Antibacterial Surfaces for Joint Arthroplasty Implant Applications

Area of Science:

• Biomaterials Science
• Infectious Diseases
• Orthopedic Surgery

Background:

• Prosthetic joint infections (PJIs) affect 1-2% of joint arthroplasties, posing significant mortality risks.
• Current treatments with intravenous antibiotics are often ineffective against biofilms and tissue-bound pathogens.
• There is a critical need for innovative strategies to prevent and treat PJIs.

Purpose of the Study:

• To review methodologies for developing antibacterial-coated implants for prosthetic joint applications.
• To emphasize studies with in vivo testing for potential clinical translation.
• To identify promising strategies for reducing infection-related surgical failures.

Main Methods:

• Comprehensive literature review of techniques for creating antibacterial coatings.
• Analysis focused on studies incorporating antimicrobial agents into implant coatings.
• Emphasis on in vivo efficacy and safety data.

Main Results:

• Various coating techniques demonstrate potential for delivering antimicrobial agents.
• Successful coatings require broad-spectrum activity, low toxicity, cost-effectiveness, and bone healing support.
• In vivo studies are crucial for validating clinical applicability.

Conclusions:

• Antibacterial-coated implants represent a promising advancement in preventing PJIs.
• Further research and in vivo validation are essential for clinical implementation.
• Developing effective coatings can significantly reduce surgical failures due to infection.
