Regenerative approaches in chronic wounds should be considered only after the reason the wound is not healing has been investigated. A wound caused by poor blood flow, infection, pressure or uncontrolled diabetes cannot be solved by a supportive product alone.
Why Must the Cause Be Investigated First?
Chronic wounds may be venous, arterial, diabetic, pressure-related or mixed. Each has a different treatment priority. Restoring blood flow, controlling infection and reducing pressure are often more important than adding any regenerative product.
How Is PRP Positioned in Chronic Wounds?
PRP may be considered as an adjunct in selected wounds because platelets contain growth factors involved in tissue repair. It should be used as part of a comprehensive plan, not as a standalone promise.
Why Are Exosomes Being Studied?
Exosomes are being researched for their potential role in cell signaling, inflammation balance and tissue repair. However, product quality, regulation and clinical evidence must be carefully reviewed.
Which Wound Types May Be Considered?
- Selected diabetic foot wounds
- Venous ulcers after pressure control
- Arterial wounds after revascularization
- Pressure ulcers with adequate offloading
- Slow-healing surgical or traumatic wounds in selected patients
Factors That Affect Success
- Blood flow to the wound
- Infection control
- Blood sugar control
- Nutrition and protein intake
- Pressure relief
- Smoking status
- Regular follow-up and dressing quality
Questions Patients Should Ask
- What is the main reason my wound is not healing?
- Has circulation been checked?
- Is there infection or pressure on the wound?
- What product will be used and what evidence supports it?
- What result is realistic for my case?
