Treatment of Plantar Fasciitis
Start with plantar fascia-specific stretching exercises for 8-12 weeks combined with appropriate footwear, ice massage, and NSAIDs as first-line therapy. 1, 2
Initial Conservative Management (First 3 Months)
Core Treatment Components
- Implement plantar fascia-specific stretching exercises supervised by a qualified healthcare professional for 8-12 weeks, as this has demonstrated benefit 1
- Prescribe calf stretching exercises in addition to plantar fascia stretches 2, 3
- Recommend proper footwear that fits the foot shape appropriately—avoid walking barefoot or in thin-soled slippers both indoors and outdoors 1
- Apply ice massage to the affected area 2, 3
- Consider NSAIDs for pain relief and potential disability reduction, though evidence shows only modest benefit with a trend toward improvement between 2-6 months 2, 4
Activity Modification
- Reduce cyclical repetitive loading of the plantar fascia during the treatment phase regardless of chosen modality 3
- Address risk factors including prolonged standing, obesity, and limited ankle dorsiflexion 2
Adjunctive Measures with Limited Evidence
Orthotic Interventions
- Plantar soft insoles have demonstrated limited evidence of benefit and are reasonable to try given low cost and ease of use 5
- Note that many standard treatments including night splints and orthoses have not shown benefit over placebo in higher-quality studies 2
Diagnostic Imaging (If Pain Persists Beyond 3 Months)
- Obtain ultrasonography as a reasonable and inexpensive diagnostic tool for persistent pain despite conservative treatment 2
- Ultrasound shows 80% sensitivity and 88% specificity compared to MRI 6
- Consider MRI if more detailed characterization of the plantar fascia and adjacent structures is needed, as it is the most sensitive imaging study 6
Second-Line Interventions for Recalcitrant Cases
Injection Therapy
- Corticosteroid injections (local or via iontophoresis) provide short-term pain relief with limited evidence of benefit 2, 5
- Weigh risks carefully: fat pad atrophy and plantar fascia rupture are potential complications 3
- Effects are transient and should only be considered when conservative options fail 5
Advanced Therapies
- Ultrasonography-guided focal extracorporeal shock wave therapy is useful for chronic plantar fasciitis in recalcitrant cases 3
- Endoscopic fasciotomy may be required in patients with continued activity-limiting pain despite exhausting all nonoperative options 2
Expected Outcomes and Timeline
- 80% of patients improve within 12 months with proper conservative treatment 2
- Approximately 90% of patients respond to nonsurgical treatment ultimately, though the condition is frequently resistant to initial interventions 7
- Pain typically manifests as stabbing, nonradiating discomfort in the morning at the proximal medioplantar foot surface, worsening at day's end 2
Critical Pitfalls to Avoid
- Do not rely solely on night splints or standard orthoses as primary treatment—evidence does not support their superiority over placebo 2
- Avoid premature surgical intervention—exhaust conservative options first given the high success rate of nonsurgical management 2, 7
- Do not overlook proper footwear counseling—inappropriate footwear undermines other interventions 1
