Wound healing is a complex and multistage process that incorporates precise cellular and molecular coordination. The presence of biofilms in chronic wounds adversely affects the wound healing process, as it prolongs the closure of the wound, thus sustaining chronic inflammation. Current data suggest that biofilms are present in almost all chronic wounds, which leads to significant challenges in diagnosis and treatment. Traditional detection methods, such as cultures and light microscopy, often fail to detect biofilms; however, sophisticated molecular and imaging techniques are constrained by their expense and accessibility. Chronic wound management, therefore, has progressed from conventional antimicrobial application to integrated methodologies that incorporate biofilm debridement, antibiofilm dressing, negative pressure wound therapy, and innovative enzyme or nanoparticle interventions. This review highlights the clinical significance of biofilm presence as a barrier in chronic wound healing, assesses diagnostic and therapeutic innovations, and stresses the urgent need to improve patient outcomes.
