Treatment of Plantar Fasciitis
Start with plantar fascia-specific stretching, ice massage, and NSAIDs as first-line therapy, recognizing that 80-90% of patients will improve with conservative treatment within 12 months. 1, 2
Initial Conservative Management (First 6-12 Weeks)
Core Treatment Components
- Plantar fascia-specific stretching exercises should be performed daily, as this is one of the most evidence-supported interventions 3, 2
- Calf stretching to address Achilles tendon tightness, a common contributing factor 1, 3
- Ice massage applied to the heel for pain relief 1, 2
- Oral NSAIDs (such as celecoxib) can provide additional pain relief and decrease disability, particularly between 2-6 months of treatment, though improvement also occurs with conservative measures alone 4
- Activity modification to reduce repetitive loading of the plantar fascia during the treatment phase 3
Adjunctive Measures
- Appropriate orthotics for patients with biomechanical abnormalities like excessive foot pronation, pes cavus, or pes planus 3, 5
- Viscoelastic heel cups may provide cushioning 4
- Weight reduction if obesity is present, as this is a significant risk factor 1, 5
Second-Line Treatments (If Pain Persists Beyond 6-12 Weeks)
Physical Therapy Modalities
- Night dorsiflexion splinting to maintain stretch of the plantar fascia overnight 4, 3
- Formal physical therapy if patient-directed treatments fail 1
Corticosteroid Injections
- Consider for persistent pain, but recognize that effects are short-lived 3
- Weigh risks carefully: fat pad atrophy and plantar fascia rupture are potential complications 3
- Should not be considered a definitive solution but rather a temporizing measure 3
Diagnostic Imaging (Only If Needed)
When to Image
- Reserve imaging for recalcitrant cases lasting beyond 3 months despite treatment 1, 2
- Use imaging to rule out other heel pathology when diagnosis is uncertain 1
Imaging Modality Selection
- Ultrasonography is reasonable and inexpensive, with 80% sensitivity and 88% specificity compared to MRI 6, 7, 2
- MRI is the most sensitive imaging study for plantar fasciitis diagnosis 6, 7
- Ultrasound elastography shows even higher diagnostic accuracy (95% sensitivity, 100% specificity) 6, 7
Refractory Cases (Pain Persisting ≥6 Months)
Advanced Interventions
- Extracorporeal shock wave therapy (ESWT) for chronic plantar fasciitis unresponsive to conservative measures 1, 3
- Endoscopic plantar fasciotomy may be required only after exhausting all nonoperative options 2
Key Clinical Pearls
Diagnostic Features
- Classic presentation: stabbing, non-radiating pain in the proximal medioplantar foot, worst with first steps in the morning or after prolonged sitting 1, 2
- Physical exam: tenderness to palpation at the medial plantar calcaneal region and anteromedial calcaneus 1, 2
- Provocative test: pain elicited by passive ankle/first toe dorsiflexion 1
Common Pitfalls to Avoid
- Do not routinely use night splints as standard treatment—evidence does not show benefit over placebo 2
- Do not rely solely on corticosteroid injections given short-lived effects and complication risks 3
- Do not order imaging initially—diagnosis is primarily clinical 1, 2
- Recognize this is a degenerative process (plantar fasciopathy), not inflammatory, despite the "-itis" terminology 2
