Skin grafting is a valuable tool in the diabetic foot wound care armamentarium that is underutilized in many practices — often because the timing, preparation, and patient selection required for graft success are not well understood. When properly applied to appropriately prepared wounds with adequate vascular perfusion, split-thickness skin grafting (STSG) can dramatically accelerate closure of wounds that would otherwise require months of standard wound care.
When Is Skin Grafting Appropriate?
Skin grafting is most appropriate for clean, granulating wounds with adequate underlying tissue perfusion that have plateaued in healing progress despite optimized wound care — typically wounds larger than 2–3 cm² that are not progressing toward spontaneous closure. Pre-graft criteria include: wound bed with >75–80% granulation tissue and minimal slough; no active clinical infection (though bacterial colonization below 10^5 organisms/gram does not preclude grafting); adequate vascular supply (TcPO2 ≥35–40 mmHg at the wound site, or post-revascularization with documented perfusion improvement); and blood glucose management optimized (HbA1c ideally below 9%).
Split-Thickness Skin Graft Technique
The donor site — most commonly the anterolateral thigh — is harvested at 10–14 thousandths of an inch thickness using a dermatome, creating a sheet graft or meshed graft (typically 1.5:1 meshing ratio for diabetic foot wounds to allow fluid egress and expand coverage). The wound bed is debrided sharply immediately before graft placement to remove any fibrinous layer that would inhibit adherence. The graft is secured with staples or absorbable sutures, covered with non-adherent dressing and bolster to maintain contact, and protected from shear forces for 5–7 days until initial neovascularization (graft “take”) occurs.
Outcomes and Alternatives
STSG take rates for properly selected diabetic foot wounds are 70–85% in published series. Alternatives to autologous STSG include bioengineered skin substitutes (Dermagraft, Apligraf, OASIS) which avoid donor site morbidity at higher cost — these products are particularly valuable for patients with limited donor site options or poor wound healing capacity. Cellular and/or tissue-based products (CTPs) have Medicare reimbursement for qualifying diabetic foot ulcers under specific coverage criteria. Dr. Biernacki at Balance Foot & Ankle provides comprehensive diabetic foot wound care including biological and autologous skin grafting for appropriate patients.

Why Regular Podiatric Care Is Essential for Diabetics
Diabetes affects the feet in two critical ways that work together to create risk: neuropathy (loss of protective sensation) and peripheral arterial disease (reduced circulation). Together, these mean that small injuries can go unnoticed and heal poorly — creating a pathway to serious infection.
The Numbers That Matter for Your Feet
- HbA1c below 7%: The ADA goal for most diabetics — higher levels accelerate neuropathy and circulation damage
- Annual comprehensive foot exam: Standard of care for all diabetics
- Daily foot inspections: Check for cuts, blisters, redness, swelling, or changes in skin color
- Never barefoot: Loss of sensation means you may step on something without feeling it
At Balance Foot & Ankle, we see diabetic patients for comprehensive foot care including neuropathy screening, nail care, wound assessment, and diabetic orthotics.
