Chronic wounds (pressure ulcers, diabetic foot ulcers, venous leg ulcers) fail to heal within 4 weeks and pose infection risk and functional impairment. Treatment aims to control infection, promote tissue regeneration, and achieve closure.
Wound care fundamentals include regular cleaning, debridement (removal of dead tissue), and appropriate dressing selection: antimicrobial dressings for infected wounds, moist-environment dressings (alginates, foams) for granulation, and pressure-offloading devices (for pressure/diabetic ulcers). Compression therapy for venous ulcers and blood-pressure control reduce underlying pathology. Systemic antibiotics treat active infection; topical antibiotics are used cautiously (risk of resistance). Addressing comorbidities—tight glycaemic control in diabetes, optimised nutrition, adequate blood flow—accelerates healing. Negative-pressure wound therapy (NPWT, vacuum-assisted closure) stimulates blood flow and granulation in stubborn wounds. Skin grafting—split-thickness or full-thickness—closes large wounds if conservative measures plateau. Enzymatic debridement with collagenase or other agents removes necrotic tissue selectively.
Honey-based antimicrobial dressings (manuka honey) have evidence for wound healing and are increasingly used. Herbal preparations (calendula, aloe vera) are traditional but evidence is limited. Hyperbaric oxygen therapy (HBOT) is approved for diabetic foot ulcers and chronic osteomyelitis; it increases tissue oxygenation and promotes healing, though cost and access limit use. Ultrasound therapy and electrical stimulation are emerging with modest evidence. Silk-based dressings and advanced biomaterials provide moist environments promoting healing.
Regenerative approaches for chronic wounds include platelet-rich plasma (PRP) injected or applied topically to stimulate growth factors and tissue repair. Bone-marrow or adipose-derived mesenchymal stem cells are being investigated for promoting angiogenesis (new blood-vessel formation) and collagen deposition. Acellular dermal scaffolds seeded with stem cells are in clinical trials for large chronic ulcers. These therapies show promise but remain investigational in many settings. Candidacy typically requires failed standard care over 3+ months. Explore regenerative wound-healing options and suitability evaluation.

Chronic wounds stall due to poor blood supply (vascular insufficiency), persistent infection, inadequate nutrition, or systemic disease (diabetes, immunosuppression). Addressing underlying pathology—improving circulation, tight glucose control, protein intake—is crucial. Without this, topical care alone cannot achieve healing.
Guidelines suggest 4–12 weeks of optimised standard care (debridement, appropriate dressing, NPWT if available, infection control) before considering surgery. If progress is evident, continue; if plateaued despite best care, grafting or advanced therapies should be considered.
Adequate protein, vitamin C, zinc, and overall calorie intake are essential for new tissue formation and infection fighting. Malnutrition delays healing dramatically. Nutritional assessment and supplementation (oral supplements, tube feeding if needed) are foundational alongside medical wound care.
