Treatment of Plantar Fasciitis
Start immediately with plantar fascia-specific stretching exercises and calf stretching—this is the single most important intervention for plantar fasciitis and should be performed daily. 1
First-Line Conservative Treatment (Weeks 0-6)
The initial approach should combine multiple evidence-based interventions simultaneously:
- Stretching exercises targeting both the plantar fascia and calf muscles form the cornerstone of treatment and must be performed consistently 1, 2
- Ice massage to the affected heel, particularly after activity, helps reduce pain 1
- Over-the-counter heel cushions and arch supports provide immediate symptomatic relief 1
- Weight loss if the patient is overweight or obese, as increased BMI is a significant risk factor 1, 3
- Footwear modifications: avoid flat shoes and barefoot walking entirely 1
- Activity modification to decrease repetitive loading of the plantar fascia during the treatment phase 2
- Padding and strapping of the foot for additional support 1
- Night splints to maintain dorsiflexion during sleep 1
With proper conservative treatment, approximately 80-90% of patients improve within 12 months 3, 4. The natural history favors resolution with conservative measures in about 90% of cases 4.
Second-Line Interventions (After 6 Weeks of Failed Conservative Treatment)
If symptoms persist beyond 6 weeks despite adherence to initial treatment:
- Customized orthotic devices tailored to the patient's specific foot structure 1
- Corticosteroid injections may provide pain relief, though effects are short-lived and carry risks of fat pad atrophy and plantar fascia rupture 1, 2
- Immobilization via casting or fixed-ankle walker-type device during activity 1
Important caveat: While corticosteroid injections can help with pain, weigh the temporary benefit against the risk of complications, particularly fat pad atrophy which can worsen long-term outcomes 2.
Advanced Interventions (For Recalcitrant Cases)
For chronic plantar fasciitis unresponsive to 3-6 months of conservative treatment:
- Ultrasonography-guided focal extracorporeal shock wave therapy (ESWT) is the preferred advanced non-surgical option for recalcitrant cases 1, 2
- Cast immobilization if not previously attempted 1
- Surgical intervention (plantar fasciotomy, either open or endoscopic) should be reserved only when all conservative measures have been exhausted, with success rates of 70-90% 1, 5
Diagnostic Considerations
- Plantar fasciitis is predominantly a clinical diagnosis based on characteristic stabbing, non-radiating pain in the proximal medioplantar foot that is worst with first steps in the morning and worsens at day's end 3
- Physical examination reveals tenderness at the anteromedial calcaneus at the proximal plantar fascial insertion 3
- Ultrasonography is reasonable and inexpensive for patients with pain persisting beyond 3 months despite treatment, with 80% sensitivity and 88% specificity compared to MRI 1, 3
Common Pitfalls to Avoid
- Do not rush to corticosteroid injections in the first 6 weeks—stretching exercises are more important and have better long-term outcomes 1
- Recognize that many "standard" treatments like night splints and orthoses have not consistently shown benefit over placebo in rigorous studies, though guidelines still recommend them 3
- Surgery should truly be a last resort after exhausting all conservative options, as 80-90% of patients improve without it 6, 3, 4
