Prosthetic joint infections (PJIs) remain a significant challenge, occurring in 1% to 2% of joint arthroplasties and potentially leading to a 20% to 30% mortality rate within 5 years. The primary pathogens responsible for PJIs include Staphylococcus aureus, coagulase-negative staphylococci, and Gram-negative bacteria, typically treated with intravenous antibiotic drugs. However, this conventional approach fails to effectively eradicate biofilms or the microbial burden in affected tissues. As a result, innovative strategies are being explored to enhance the efficacy of infection prevention through the development of antibacterial-coated implants. These coatings are required to demonstrate broad-spectrum antimicrobial activity, minimal local and systemic toxicity, favorable cost-effectiveness, and support for bone healing. In the present review, the analysis of various methodologies for developing antibacterial coatings was performed, emphasizing studies that conducted in vivo tests to advance potential clinical applications. A diversity of techniques employed for the development of coatings incorporating antimicrobial agents highlights promising avenues for reducing infection-related surgical failures.
人工关节感染(PJI)仍然是一个重大挑战,在1%至2%的关节置换术中发生,并可能导致5年内死亡率达到20%至30%。导致PJI的主要病原体包括金黄色葡萄球菌、凝固酶阴性葡萄球菌和革兰氏阴性菌,通常用静脉抗生素药物治疗。然而,这种传统方法未能有效根除受影响组织中的生物膜或微生物负荷。因此,正在探索创新策略,通过开发抗菌涂层植入物来提高感染预防的效果。这些涂层需要表现出广谱抗菌活性、最小的局部和全身毒性、良好的成本效益以及对骨愈合的支持。在本综述中,对开发抗菌涂层的各种方法进行了分析,重点是进行体内试验以推进潜在临床应用的研究。用于开发含有抗菌剂涂层的多种技术突出了减少感染相关手术失败的有前景的途径。
