How is it different from a skin graft?
A free flap brings tissue with its own blood vessels, which are reconnected at the wound.
A skin graft has no surgically reconnected blood supply and depends on the wound bed to nourish it.
Scar, Skin & Wound
Free Flap Wound Reconstruction
Free flap wound reconstruction moves living tissue from another part of your body and reconnects its blood vessels to cover a complex wound.
Does it require a hospital stay?
Usually, yes, with close monitoring of blood flow to the flap.
The length of stay depends on the wound, flap, medical needs, and mobility.
Is it right for every wound?
No. It is generally considered when simpler coverage is unlikely to provide reliable healing.
Consultation includes checking circulation, infection, available donor tissue, and fitness for a lengthy operation.
01 · Overview
Living tissue coverage for a complex wound
Free flap reconstruction transfers skin, fat, muscle, bone, or a combination of tissues to a wound. The surgeon separates the tissue from its original blood supply and joins its vessels to vessels near the wound using microsurgery. [1]
This approach may cover exposed bone, tendon, or hardware, fill a deep tissue gap, or replace damaged tissue after injury, infection treatment, or cancer surgery. Cleaning the wound and addressing infection or poor circulation may be needed before coverage. [1]
Unlike a local or pedicled flap, a free flap is completely detached before transfer. It is also different from scar revision: the main goal is wound coverage and restoration of useful tissue, not simply making a scar less visible. [2]

Why might a wound need tissue from somewhere else?
Nearby tissue may be damaged, scarred, irradiated, or insufficient to cover the wound. A distant donor site can provide healthier tissue with the thickness and structure needed.
Who may be involved in planning?
A reconstructive microsurgeon may work with wound-care, orthopedic, vascular, infectious-disease, or cancer specialists. The team depends on the wound's cause and location.
02 · Concerns & Goals
What may bring you to a consultation
A wound that has not healed can affect comfort, movement, and daily life. Your team will assess both the wound and why it is having trouble healing.
A wound that stays open
Repeated breakdown or slow healing may lead to discussion of more substantial tissue coverage.
Exposed deeper structures
Bone, tendon, nerves, or hardware may need living tissue coverage rather than a skin graft alone.
Missing or damaged tissue
Trauma, infection treatment, or removal of a tumor can leave a gap that needs reconstruction.
Loss of everyday function
Pain, drainage, limited movement, or difficulty walking may shape your goals, along with the health of the underlying structures.
03 · Options
How the approaches differ
These are possible free flap approaches, not interchangeable choices. Your surgeon recommends tissue based on the wound, blood vessels, donor-site effects, and your goals.
Skin-and-fat flap
Provides skin coverage and soft-tissue padding.
How it worksSkin and underlying tissue are transferred with their supplying vessels.
May suitSelected wounds needing flexible coverage or padding over deeper structures.
Main tradeoffThe flap may be bulky, and the donor area has its own scar and healing needs.
Muscle flap
Provides living muscle to cover or fill a deeper wound.
How it worksMuscle is transferred with its vessels and may be covered with a skin graft.
May suitSelected wounds with a deep cavity or substantial soft-tissue loss.
Main tradeoffRemoving muscle can affect donor-site strength or function; a skin graft adds another healing area.
Perforator flap
Transfers skin and fat while preserving most or all of the underlying muscle.
How it worksSmall vessels passing through or between deeper tissues are carefully dissected and reconnected.
May suitSelected patients with suitable vessel anatomy and a need for soft-tissue coverage.
Main tradeoffDissection can be complex, and muscle preservation does not eliminate donor-site complications.
Bone-containing flap
Replaces missing bone as well as soft tissue when needed.
How it worksLiving bone, sometimes with skin or muscle, is transferred with its blood supply.
May suitSelected complex wounds with a structural bone defect.
Main tradeoffBone healing, fixation, and donor-site recovery can add complexity and rehabilitation needs.
Flap names often describe either the donor tissue or its blood supply, so these categories can overlap. Ask which tissue will be moved and what that means for both treatment sites. [1] [2].
Will the wound be closed in one operation?
Sometimes, but reconstruction may be staged. Wound cleaning, infection treatment, circulation procedures, or temporary dressings may come first. Later surgery may address contour, function, or incomplete healing.
How is the donor site chosen?
The surgeon considers tissue size and thickness, vessel anatomy, previous surgery, strength and mobility needs, and whether the donor wound can close directly or needs a skin graft.
04 · Results
What may improve and what may remain
Wound coverage
The goal is durable living tissue over the wound.
- Successful coverage may protect exposed structures and reduce ongoing dressing needs.
- Healing still depends on circulation, infection control, nutrition, and the condition of nearby tissue.
Function and comfort
Coverage can support rehabilitation, but it cannot reverse every underlying injury.
- Movement and comfort depend partly on the health of bone, joints, tendons, and nerves.
- Physical or occupational therapy may be needed once the reconstruction can tolerate it.
Appearance and sensation
The reconstructed area will not look or feel exactly like the original tissue.
- Color, thickness, hair growth, and sensation may differ.
- Both the wound and donor site develop scars; selected patients may discuss later contour adjustment.
Flap survival is only one part of recovery. Wound healing, donor-site healing, and functional improvement are separate goals, and further treatment may be needed. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery involves protecting the transferred tissue and helping the donor site heal. Positioning, dressings, movement, and weight-bearing plans are specific to your reconstruction.
Step 1 · Surgery and immediate recovery
Treatment day
The team prepares the wound, transfers tissue, and reconnects blood vessels. After anesthesia, staff monitor your overall condition and the flap's circulation.
Step 2 · Early hospital recovery
Close monitoring
Frequent checks look for changes in blood flow. A circulation problem may require urgent return to the operating room. Pain control and safe movement are tailored to both surgical sites.
Step 3 · After discharge
Healing at home
Your team provides a wound-care plan, activity limits, and follow-up schedule. You may need help with daily tasks, dressings, mobility, or transport.
Step 4 · Following weeks to months
Rehabilitation and reassessment
Activity increases as healing allows. Strength, swelling, sensation, and scars may continue changing for months, and some reconstructions need additional procedures.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
WorkPlanning context: Timing depends on job demands and both surgical sites.What affects it: Desk work may resume before physical work, but returning to work does not mean healing is complete.
Walking and weight bearingPlanning context: Especially important for leg or foot reconstruction.What affects it: Your team decides when the limb can hang down or bear weight; a mobility aid may be needed.
Exercise and liftingPlanning context: Restrictions depend on the flap and donor tissue.What affects it: Pressure, stretching, or heavy lifting can stress healing areas. Rehabilitation should follow your surgeon's plan.
DrivingPlanning context: Requires safe movement, alertness, and reliable vehicle control.What affects it: Do not drive while taking impairing pain medicine; ask when your wounds and mobility permit safe driving.
Follow your surgical team's instructions rather than a general recovery calendar. Ask before applying pressure, heat, or cold to the flap, particularly if sensation is reduced.
Before your procedure
- Review the wound's cause, previous treatments, infections, and any implanted hardware with your team.
- Provide a complete medication and supplement list; ask which medicines need adjustment rather than stopping them yourself.
- Discuss smoking, vaping, and all nicotine use, which can interfere with healing.
- Ask whether circulation testing, imaging, laboratory tests, or infection treatment is needed.
- Discuss nutrition, diabetes management, and other health conditions that may affect recovery.
- Arrange transport, home support, and any equipment needed for your expected movement restrictions.
Why are flap checks so frequent?
The reconnected vessels can develop a blockage or other blood-flow problem. Early recognition gives the surgical team an opportunity to intervene, although the flap cannot always be saved.
Will I need therapy?
You may need physical or occupational therapy for movement, strength, walking, or daily tasks. The starting point depends on flap stability and any associated bone, tendon, or nerve repair.
06 · Safety
Risks and what your clinician assesses
Swelling, bruising, soreness, fatigue, altered sensation, and scars at both sites are common during recovery. The pattern should be reviewed with your team, especially if symptoms worsen rather than improve.
Blood-flow problems and flap loss
Clotting or poor circulation can cause partial or complete flap loss. Urgent surgery or a different reconstruction may be needed.
Infection and delayed healing
Infection, wound opening, or persistent drainage may require antibiotics, wound care, or additional surgery.
Bleeding and fluid collections
Blood or other fluid can collect at either site and may need drainage or another procedure.
Donor-site problems
The tissue-removal site can develop healing problems, weakness, contour changes, or functional limitations.
Lasting tissue changes
Scarring, numbness, pain, swelling, or bulky coverage may persist. Revision does not guarantee correction.
Anesthesia and blood clots
A lengthy operation and reduced mobility carry risks, including anesthesia complications and clots in the legs or lungs.
Discuss these risks and your individual health history with your surgeon. [1]
What your clinician assesses
- Wound size, depth, infection status, and exposed structures
- Blood flow near the wound and at possible donor sites
- Medical conditions, nutrition, medications, and nicotine use
- Donor-site function, rehabilitation needs, and available home support

08 · Questions
Common questions
Does “free flap” mean there is no charge?
No. “Free” means the tissue is detached from its original blood supply before being transferred and reconnected.
Is this the same as a skin graft?
No. A skin graft relies on the receiving wound bed for a new blood supply. A free flap has vessels that the surgeon reconnects directly.
Can a free flap treat infection by itself?
No. Infected or dead tissue may need removal, and antibiotics or hardware treatment may be necessary. Flap coverage is one part of the overall plan.
What happens if the flap does not survive?
The team assesses the cause and the wound's needs. Treatment may include urgent vessel repair, removal of nonliving tissue, further wound care, or another reconstruction.
