Walking on Bone? Fat Pad Atrophy and How Liposana May Help

Does walking barefoot on a hard floor feel as though you are walking directly on bone? Do the heel or ball of your foot feel bruised after standing? One possible explanation is plantar fat pad atrophy, a loss of the natural cushioning beneath the foot. These symptoms can have other causes, so the first step is an examination, not an injection.

At Vertex Podiatry in Columbus, Ohio, Dr. Guy Golan offers Liposana for selected patients with fat pad loss. This donor-derived adipose tissue graft is an option to discuss when cushioning and pressure relief alone have not adequately addressed symptoms. It is not appropriate for every painful foot, and improvement is not guaranteed.

What is fat pad atrophy?

The underside of the heel and the ball of the foot contain specialized fatty tissue held within a supportive network. Together, these structures help cushion the bones and distribute pressure during standing and walking. With atrophy, that protective tissue becomes thinner or less effective. In some feet, the cushioning also shifts away from the areas that need it most.

When less padding separates a bony prominence from the ground, everyday activities may become uncomfortable. The problem can affect the heel, the area beneath the metatarsal heads at the ball of the foot, or both.

What does loss of foot cushioning feel like?

• A bruised or deep aching feeling beneath the heel or ball of the foot.
• Discomfort with prolonged standing, walking, or higher-impact activity.
• Pain that is especially noticeable barefoot on tile, hardwood, or concrete.
• Tenderness beneath prominent bones, sometimes with a recurring pressure callus.

These are clues, not a diagnosis. Plantar fasciitis, arthritis, a stress fracture, a plantar plate injury, or a nerve problem can cause overlapping symptoms. Burning, tingling, or numbness may point toward nerve involvement rather than cushioning loss alone. More than one condition can be present.

Why can the fat pad become thinner?

Age-related changes, repeated mechanical loading, previous injury, foot structure, and certain inflammatory or metabolic conditions may contribute. Prior corticosteroid injections can sometimes cause local fat tissue thinning. Not everyone who has received a cortisone injection develops fat pad atrophy, and prior treatment does not establish the cause of a person's pain.

During an evaluation, Dr. Golan reviews the location and timing of symptoms, footwear, activity, previous procedures, skin condition, sensation, circulation, and how the foot bears weight. Ultrasound or other imaging may be appropriate to assess tissue or rule out another problem, but not every patient needs every test.

What should you try before an injection?

Conservative care remains important and may provide enough relief without a procedure. Options can include:

• Cushioned, supportive shoes: Replace worn-out cushioning and avoid going barefoot on hard floors when it triggers pain.
• Heel cups, metatarsal pads, or orthotics: Correct placement matters. A pad placed directly beneath a painful pressure point can make symptoms worse.
• Activity and pressure changes: Adjust prolonged standing and impact activity, and consider cushioned indoor footwear.
• Care for contributing problems: Address pressure calluses and relevant foot mechanics or medical conditions with professional guidance.

These measures protect the foot even if a graft is later considered. An injection does not replace appropriate footwear or correct every structural cause of excess pressure.

What is Liposana, and how is it different from cortisone?

Liposana is a cryopreserved human adipose tissue allograft. In plain language, it is donated human fatty tissue prepared for use in areas with an adipose tissue defect. The manufacturer describes its purpose as repair, replacement, or reconstruction of those defects while retaining the tissue's native structure.

• It is not cortisone: A corticosteroid injection targets inflammation. Liposana is intended to supplement deficient adipose tissue and provide structural cushioning.
• It is not your own harvested fat: Autologous fat grafting takes tissue from another part of the patient's body. Liposana uses donor tissue, so it does not require a separate fat-harvesting procedure from the patient.
• It is not a synthetic cosmetic filler: Different injectable materials have different properties, evidence, risks, and regulatory considerations. They should not be treated as interchangeable.

The manufacturer reports processing under FDA human tissue regulations, including 21 CFR Part 1271. That should not be interpreted as a claim that Liposana is an FDA-approved drug or a proven cure for all heel or forefoot pain. Dr. Golan can discuss the proposed use, alternatives, and consent considerations for your situation.

What benefits are possible, and what does the evidence show?

The goal is to supplement cushioning in a deficient area and potentially improve comfort with weight-bearing. Some patients may experience less pressure-related pain or improved activity tolerance. The degree of benefit varies, and a change in measured tissue thickness does not necessarily mean a corresponding change in pain.

A published 2025 pilot study of Liposana included 9 patients and 10 treated feet with forefoot pain related to fat pad atrophy. At 12 weeks, most treated feet had increased measured tissue thickness and most patients had improved function scores. However, the study was small, retrospective, and had no untreated comparison group. The author disclosed a consulting relationship with the company marketing the product.

Those findings are encouraging early evidence, not a guarantee of results or proof of long-term durability. They also should not be assumed to apply equally to heel pain, neuropathy, every pressure lesion, or every patient. Larger studies and longer follow-up are needed. Results from studies of a patient's own harvested fat or a different allograft product should not be presented as Liposana-specific results.

Who may be a candidate?

A discussion may be reasonable when an examination supports symptomatic fat pad loss, discomfort persists despite appropriate pressure relief, and the likely benefits justify the risks. Circulation, skin health, sensation, medical history, the location of pain, and the ability to follow an offloading plan all matter.

Diabetes, neuropathy, poor circulation, an open wound, or possible infection require individualized assessment. Liposana is not a substitute for treating an infection, managing a wound, or addressing a fracture or significant structural problem. A request for an injection does not establish that it is the best treatment.

What happens during treatment and recovery?

If treatment is appropriate, the clinician discusses the proposed site, donor tissue, risks, alternatives, and aftercare before proceeding. Local anesthesia is commonly used for adipose graft placement. The tissue is placed beneath the skin in the area of deficiency using a clinician-selected technique. Exact details depend on the clinical plan.

Afterward, soreness, swelling, or bruising can occur. You may need protective footwear, padding, and temporary restrictions on weight-bearing, prolonged standing, running, or other impact activity. Do not assume that an office procedure means unrestricted walking or an immediate return to work or sports. Your instructions and follow-up schedule should be tailored to the treatment site and your health.

Risks include infection, bleeding, persistent pain, local tissue reactions, uneven cushioning, injury to nearby structures, and insufficient or short-lived improvement. Donor screening and tissue processing reduce certain risks but cannot eliminate all risks, including disease transmission. Discuss the current product information and procedure-specific risks before treatment.

How long does Liposana last, and is it covered by insurance?

There is no guaranteed duration of benefit. Pressure patterns, activity, underlying conditions, graft response, and continued footwear support may affect the result. Repeat treatment may be discussed in some cases, but it should not be assumed to be necessary or effective for everyone.

Cost and insurance coverage should be discussed with our office before proceeding. Coverage is not guaranteed simply because an evaluation or another foot treatment is covered.

How is Liposana scheduled at Vertex Podiatry?

We offer Liposana and currently order it per request. Start with an evaluation so Dr. Golan can determine whether fat pad atrophy is the source of your symptoms and whether the treatment is appropriate. If you decide to proceed, our office coordinates product ordering and the procedure appointment. Booking an initial evaluation does not mean an injection will be performed at that visit.

Learn more about our fat pad injection treatment options, or schedule an evaluation online. You can also call (614) 328-5561. Dr. Golan also speaks Spanish, and an initial consultation in Spanish can be scheduled online.

Seek prompt care for an open sore, spreading redness, drainage, fever, a suddenly swollen foot, or inability to bear weight. New foot wounds in someone with diabetes or reduced sensation should not wait for a routine injection consultation.
