Treatment of Plantar Fasciitis
The most effective treatment for plantar fasciitis involves a stepwise approach starting with conservative measures including regular calf-muscle stretching, plantar fascia-specific stretches, appropriate footwear, and over-the-counter orthoses, followed by more advanced interventions only if initial treatments fail. 1
Initial Conservative Treatment (First 6 Weeks)
Patient-directed measures:
- Regular calf-muscle and plantar fascia-specific stretching exercises (most important initial intervention) 1, 2
- Ice massage to the affected area, especially after activity 1, 2
- Over-the-counter heel cushions and arch supports 1
- Weight loss if the patient is overweight or obese 1, 2
- Activity modification to decrease repetitive loading of the plantar fascia 3
- Avoidance of flat shoes and barefoot walking 1
Medication:
Basic supportive treatments:
Secondary Interventions (If No Improvement After 6 Weeks)
If symptoms persist after 6 weeks of initial treatment, consider:
- Customized orthotic devices tailored to the patient's foot structure 1
- Corticosteroid injections (limited number) 1
- Note: While effective for short-term pain relief, these must be used cautiously due to risks of fat pad atrophy and plantar fascia rupture 3
- Immobilization via casting or fixed-ankle walker-type device during activity 1
Advanced Interventions (If No Improvement After 2-3 Months)
For recalcitrant cases that don't respond to previous treatments:
- Extracorporeal shock wave therapy (ESWT) - particularly ultrasonography-guided focal ESWT 1, 3
- Cast immobilization if not previously attempted 1
- Surgical intervention - plantar fasciotomy may be considered when all conservative measures have failed 1, 5
- Endoscopic fasciotomy is an option for patients with persistent pain that limits function despite exhausting non-operative treatments 2
Treatment Efficacy and Prognosis
- With proper treatment, approximately 80% of patients with plantar fasciitis improve within 12 months 2
- Conservative treatment is ultimately effective in approximately 90% of patients 6
- Surgical success rates for plantar fascia release are approximately 70-90% in recalcitrant cases 5
Diagnostic Considerations
- Plantar fasciitis is predominantly a clinical diagnosis 2
- Key symptoms include stabbing, non-radiating pain first thing in the morning in the proximal plantar surface of the foot 2
- Physical examination typically reveals tenderness at the proximal plantar fascial insertion at the anteromedial calcaneus 2
- For persistent pain beyond 3 months despite treatment, ultrasonography is a reasonable diagnostic tool 2
- US has good sensitivity (80%) and specificity (88%) in diagnosing plantar fasciitis compared to MRI 1
Common Pitfalls to Avoid
- Failing to address biomechanical factors like tight Achilles tendon 6
- Overreliance on corticosteroid injections without considering risks 3
- Premature consideration of surgical intervention before exhausting conservative options 1, 2
- Not allowing sufficient time for conservative treatments to work (most cases resolve within 12 months) 2
