Initial Treatment for Plantar Fasciitis
The initial treatment for plantar fasciitis should include stretching of the plantar fascia, ice massage, and nonsteroidal anti-inflammatory drugs (NSAIDs). 1
Pathophysiology and Clinical Presentation
- Plantar fasciitis is a common cause of inferior heel pain affecting approximately one in 10 people during their lifetime 1
- The condition is more accurately described as plantar fasciopathy rather than fasciitis, as it is primarily degenerative rather than inflammatory in nature 1
- Typical symptoms include stabbing, non-radiating pain in the proximal medioplantar surface of the foot, worst with first steps in the morning and worsening again at the end of the day 1
- Physical examination typically reveals tenderness to palpation at the proximal plantar fascial insertion at the anteromedial calcaneus 1
Conservative Treatment Algorithm
First-Line Treatments (0-3 months)
- Stretching exercises: Implement plantar fascia-specific stretching and calf stretching exercises 2
- Ice massage: Apply to the affected area to reduce pain 1
- NSAIDs: Use for pain management and to potentially reduce inflammation 1
- Activity modification: Decrease cyclical repetitive loading of the plantar fascia during the treatment phase 2
- Appropriate footwear: Supportive shoes with proper cushioning 3
Second-Line Treatments (if no improvement after 4-6 weeks)
- Night splints: May help maintain dorsiflexion during sleep, though evidence shows limited benefit over placebo 1
- Orthotic devices: Custom or over-the-counter inserts to support the arch 2
- Taping: Can provide temporary relief by supporting the plantar fascia 4
Third-Line Treatments (for persistent cases >3 months)
- Imaging: Consider ultrasonography for cases that persist beyond three months despite treatment 1
- Corticosteroid injections: Can provide short-term pain relief but carry risks of fat pad atrophy and plantar fascia rupture 2
- Extracorporeal shock wave therapy (ESWT): Consider for chronic cases unresponsive to other conservative measures 2, 5
Treatment Considerations Based on Physical Examination Findings
- Patients with severe ankle equinus (inability to dorsiflex the ankle past -5°) are nearly 4 times more likely to respond favorably to conservative treatment including Achilles tendon stretching 3
- Patients with heel valgus in relaxed stance and those with less severe first-step pain (≤7 on ordinal scale) may be less responsive to conservative care 3
Prognosis and Expectations
- With proper treatment, approximately 80% of patients with plantar fasciitis improve within 12 months 1
- Conservative treatment is ultimately effective in approximately 90% of patients 6
- Patients should be advised that resolution may take several months even with appropriate treatment 6
When to Consider Advanced Interventions
- For cases that fail to respond to 3-6 months of conservative treatment:
- Consider ultrasonography-guided focal extracorporeal shock wave therapy 2
- Noninvasive interactive neurostimulation (NIN) has shown superior results compared to electric shock wave therapy in some studies 5
- Surgical options such as endoscopic fasciotomy may be considered only after exhausting all non-operative treatment options 1
Common Pitfalls to Avoid
- Overreliance on corticosteroid injections without considering the risks of fat pad atrophy and plantar fascia rupture 2
- Failure to address underlying biomechanical factors such as tight Achilles tendon 6
- Premature consideration of invasive treatments before adequate trial of conservative measures 1
- Neglecting activity modification as part of the comprehensive treatment plan 2
