Quick Answer:
Quick Answer: Heel fat pad syndrome occurs when the protective cushioning layer under the heel bone — the plantar fat pad — thins and loses its shock-absorbing capacity due to aging, chronic high-impact activity, corticosteroid injections, or systemic conditions like rheumatoid arthritis. Unlike plantar fasciitis, fat pad atrophy causes central heel pain (directly over the heel bone) that worsens with walking on hard surfaces. Dr. Biernacki treats it with custom accommodative orthotics, silicone heel cups, and protective footwear strategies.
Understanding the Heel Fat Pad
The plantar fat pad is a specialized cushioning structure on the bottom of the heel — not simply fat, but a complex arrangement of fibro-elastic tissue compartments filled with fat cells, designed to absorb up to 110% of body weight with every heel strike. In young, healthy feet this structure is robust and resilient. But age, cumulative impact, systemic inflammation, and repeated corticosteroid injections can cause the fat pad to thin, fragment, or shift — producing a painful condition where every step feels like walking on bone.
Fat Pad Syndrome vs. Plantar Fasciitis: Key Differences
Both conditions cause heel pain, but they’re distinct. Plantar fasciitis produces pain at the medial heel — the front-inside of the heel bone — that’s worst with the first steps in the morning and improves with movement. Fat pad syndrome produces pain directly over the center of the heel — the weight-bearing surface — that worsens with walking (especially on hard floors or without shoes) and doesn’t improve with movement the way plantar fasciitis does. Clinical examination and ultrasound measurement of fat pad thickness confirm the diagnosis. Many patients have both conditions simultaneously.
Treatment: Accommodative Protection
Fat pad atrophy cannot be reversed — the specialized structure doesn’t regenerate. Treatment focuses on replacement cushioning: silicone heel cups that mimic the fat pad’s shock-absorbing properties, custom accommodative orthotics with deep heel cups and maximum cushioning, and footwear selection emphasizing maximum-cushion midsoles (Hoka, Brooks Beast, ASICS Gel Nimbus). Avoiding barefoot walking on hard surfaces is critical. Dr. Biernacki also counsels patients on avoiding further steroid injections near the fat pad, which accelerate atrophy.
When Fat Pad Syndrome Is Part of a Larger Condition
Fat pad atrophy is a recognized feature of rheumatoid arthritis, lupus, and other inflammatory conditions — the plantar fat pad is particularly susceptible to inflammation-mediated damage. In these patients, optimizing the underlying systemic condition with rheumatology co-management is part of the comprehensive treatment approach. Dr. Biernacki coordinates with patients’ rheumatologists and internists to ensure the foot care plan is consistent with systemic disease management.

✅ Pros / Benefits
- Ultrasound measurement of fat pad thickness for objective diagnosis
- Custom accommodative orthotics with maximum heel cushioning fabricated on-site
- Counsels patients on steroid injection risks near the heel fat pad
- Differentiates fat pad syndrome from plantar fasciitis — often coexisting
❌ Cons / Risks
- Fat pad atrophy is not reversible — management is ongoing, not curative
- Significant fat pad loss may require custom footwear or rocker-bottom shoe modifications
Dr. Tom Biernacki’s Recommendation
Fat pad syndrome is consistently undertreated because it gets lumped in with plantar fasciitis and given the same treatment — which doesn’t work. The fat pad can’t be stretched, and plantar fascia stretching doesn’t restore cushioning. These patients need silicone, maximum cushion, and protection. Once you give them that, most do very well.

Frequently Asked Questions
Can repeated cortisone injections cause fat pad atrophy?
Yes — steroid injections near or into the fat pad cause adipose tissue atrophy. This is why Dr. Biernacki is careful with heel injection placement and avoids intra-pad injection whenever possible.
Is fat pad syndrome permanent?
The atrophy itself is generally permanent. However, excellent symptom management is achievable with appropriate cushioning, orthotics, and footwear — most patients achieve significant pain reduction.
How is fat pad syndrome different from a bruised heel?
A bruised heel (calcaneal contusion) from acute impact is temporary — it resolves in days to weeks with rest and cushioning. Fat pad syndrome is a chronic progressive condition without an acute injury event.
Do insurance plans cover custom orthotics for fat pad syndrome?
Many plans cover custom orthotics when prescribed for a specific diagnosis such as fat pad atrophy. We verify coverage before the appointment and provide transparent cost estimates.
