What are the treatment options for plantar fasciitis?

Plantar Fasciitis Treatment

Start with plantar fascia-specific stretching exercises, ice massage, and NSAIDs as first-line therapy, as approximately 90% of patients improve with conservative treatment alone. 1, 2

Initial Conservative Management (First 4-6 Weeks)

Patient-Directed Treatments

• Plantar fascia-specific stretching is the cornerstone of treatment and should be performed multiple times daily 1, 3
• Calf stretching exercises to address limited ankle dorsiflexion, a key risk factor 2, 4
• Ice massage applied to the medial plantar heel for 15-20 minutes 1, 5
• Oral NSAIDs for pain control during the acute phase 1, 2
• Activity modification to decrease repetitive loading of the plantar fascia—reduce prolonged standing, walking, and running 3, 4
• Rest from aggravating activities 1, 5

Risk Factor Modification

• Weight reduction if BMI is elevated, as obesity is a significant risk factor 1, 2
• Footwear assessment—ensure proper arch support and cushioning 5

Physician-Prescribed Treatments (If Pain Persists Beyond 4-6 Weeks)

Physical Therapy Modalities

• Structured physical therapy focusing on stretching and strengthening protocols 1
• Foot orthotics with arch support, though evidence over placebo is limited 2, 5

Night Splinting

• Night dorsiflexion splints maintain ankle dorsiflexion during sleep, though evidence of benefit over placebo is weak 1, 3, 2

Corticosteroid Injections

• Local corticosteroid injections provide short-term pain relief but effects are temporary 1, 3
• Major caveat: Weigh benefits against risks of plantar fascia rupture and fat pad atrophy, which can cause long-term complications 3
• Reserve for patients with significant functional impairment despite other conservative measures 3

Diagnostic Imaging (If Symptoms Persist Beyond 3 Months)

• Ultrasonography is reasonable and inexpensive for recalcitrant cases—shows increased plantar fascia thickness (>4mm) and abnormal tissue signal 6, 1, 2
• MRI is the most sensitive imaging modality but typically unnecessary unless ruling out other pathology 7, 6, 1
• Ultrasound elastography demonstrates even higher diagnostic accuracy (95% sensitivity, 100% specificity) compared to standard ultrasound 7, 6
• Imaging is not needed for initial diagnosis—plantar fasciitis is predominantly a clinical diagnosis 1, 2

Advanced Treatments for Chronic Recalcitrant Cases (≥6 Months)

Extracorporeal Shock Wave Therapy (ESWT)

• Ultrasonography-guided focal ESWT is useful for chronic plantar fasciitis unresponsive to conservative treatment 1, 3
• Consider referral after exhausting standard conservative measures 3

Surgical Intervention

• Endoscopic plantar fasciotomy may be required when pain limits activity and function despite exhausting all nonoperative options 2
• Surgery should be reserved as a last resort, typically after 6-12 months of failed conservative treatment 1, 2

Treatment Timeline and Expectations

• 80% of patients improve within 12 months with proper conservative treatment 2
• 90% ultimately respond to nonsurgical management 1, 4
• Symptoms resolve more quickly when treatment begins earlier after symptom onset 5
• Treatment should be tailored based on duration of symptoms: shorter duration cases respond better to simple conservative measures, while chronic cases (>3 months) may require more aggressive interventions 1, 2

Critical Pitfalls to Avoid

• Do not delay treatment—earlier intervention correlates with faster resolution 5
• Avoid overuse of corticosteroid injections—multiple injections increase risk of plantar fascia rupture and fat pad atrophy 3
• Do not order imaging routinely—reserve for cases not responding after 3 months or when alternative diagnoses are suspected 1, 2
• Ensure compliance with stretching exercises—this is the most important modality but requires patient adherence 1, 3
