This comprehensive exploration addresses the intricate challenges posed by BJI and highlights the significant role of phage therapy as a non-antibiotic strategy.</p></div><div><h3>Methods</h3><p>BJI, which encompass prosthetic joint infections, osteomyelitis, and purulent arthritis, are exacerbated by biofilm formation on bone and implant surfaces, hindering treatment efficacy. Gram-negative bacterial infections, characterized by elevated antibiotic resistance, further contribute to the clinical challenge. Amidst this therapeutic challenge, phage therapy emerges as a potential strategy, showing unique characteristics such as strict host specificity and biofilm disruption capabilities.</p></div><div><h3>Results</h3><p>The review unveils the dynamics of phages, including their origins, lifecycle outcomes, and genomic characteristics. Animal studies, in vitro investigations, and clinical research provide compelling evidence of the efficacy of phages in treating <em>Staphylococcus aureus</em> infections, particularly in osteomyelitis cases. Phage lysins exhibit biofilm-disrupting capabilities, offering a meaningful method for addressing BJI. Recent statistical analyses reveal high clinical relief rates and a favourable safety profile for phage therapy.</p></div><div><h3>Conclusions</h3><p>Despite its promise, phage therapy encounters limitations, including a narrow host range and potential immunogenicity.
