Preparing for Biologic Allograft Application: A Patient Perspective

What Is a Biologic Allograft?

A biologic allograft is derived from donated human tissue — typically amniotic membrane, dermis, or umbilical cord — and processed to meet FDA requirements under 21 CFR Part 1271. These tissues are regulated as Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps) and are intended for homologous use.

Allografts used in wound care are acellular, meaning the cells have been removed to reduce immunogenicity. They retain important biological components such as collagen, growth factors, and extracellular matrix proteins that can support the body’s healing environment.

Before the Procedure

Before a biologic allograft is applied, patients typically undergo a wound assessment and initial wound bed preparation:

• Wound Evaluation: The healthcare provider will measure the wound dimensions, assess depth, check for infection, and determine if the wound is suitable for allograft use.
• Debridement: Any non-viable tissue is removed to create a clean wound bed, essential for graft adherence and effectiveness.
• Discussion of Expectations: Patients may be informed about the frequency of applications, how the graft will be secured, and post-procedure care.

Patients should communicate any allergies, recent illnesses, or changes in wound symptoms to the provider.

During the Application

Biologic allograft application is typically a non-surgical, in-office procedure. Here’s what the process usually involves:

1. Sterile Preparation: The area around the wound is cleaned using sterile technique.
2. Graft Placement: The biologic allograft is trimmed to the shape of the wound and gently applied to the wound bed.
3. Securing the Dressing: A secondary dressing, compression wrap, or silicone layer may be used to keep the graft in place.

The entire process usually takes less than 30 minutes, and patients can typically resume their normal activities afterward unless otherwise instructed.

After the Procedure

Following the application, patients should follow specific care instructions provided by their wound care team:

Photographs may be taken at each visit to document wound progress. The healing process is incremental and may take several weeks.

Common Patient Questions

Will I feel the biological allograft once it’s on?

Most patients do not feel the graft itself. Any discomfort is usually related to the underlying wound rather than the dressing.

Is there a risk of infection?

Biologic allografts are sterilized and screened for pathogens. Infection risk is low but still monitored during follow-up visits.

How long will I need these treatments?

The number of applications varies depending on wound type, size, and progression. Some patients see changes after a few weeks, while others require ongoing treatment.

Can I shower with the graft in place?

Your provider will advise on wound care between visits. In some cases, waterproof coverings may be recommended.

Summary for Patients

Biologic allografts are a non-invasive option used in the management of chronic wounds. For patients, the procedure involves minimal discomfort and can usually be performed during a routine clinic visit.

Being informed about the purpose, process, and follow-up involved in biologic allograft treatment can empower patients to participate actively in their wound healing plan. Ask your provider any questions specific to your case, and follow all care instructions to support the best possible outcome.
