Plantar fasciopathy, historically referred to as plantar fasciitis, is the most common cause of inferior heel pain, accounting for approximately 11% to 15% of all adult foot symptoms requiring professional care.
Epidemiology and Risk Factors¶
• Prevalence and Incidence: The condition affects one in ten people during their lifetime. In physically active populations, such as runners, the incidence ranges from 4.5% to 10.0%, with prevalence reaching up to 17.5%.
• Demographics: While it can occur at any age, the peak incidence typically occurs in adults aged 45 to 65 years. In runners, the condition tends to peak at a younger age.
• Risk Factors: Key risk factors include obesity or a high Body Mass Index (BMI), calf tightness (reduced ankle dorsiflexion), and occupations that require prolonged standing. Structural factors like pes planus (flat feet) or pes cavus (high arches) are also cited, though evidence for some of these is limited.
• Nature of Condition: It is generally considered a degenerative pathology (fasciosis) rather than a primarily inflammatory one, resulting from repetitive microtrauma and chronic overload. It is bilateral in up to one-third of cases.

Typical Presentation¶
• Onset and Pain Character: Patients usually report a gradual onset of pain under the heel. A hallmark symptom is intense pain during the first few steps in the morning or after a prolonged period of inactivity.
• Tenderness: Physical examination typically reveals a localized area of maximal tenderness over the anteromedial aspect of the inferior heel, specifically at the medial calcaneal tubercle where the fascia originates.
• Activity Patterns: The pain often lessens with gradual activity but tends to worsen by the end of the day, especially following extended weight-bearing.
• Clinical Signs: Limping may occur, and there is often notable tightness in the Achilles tendon or triceps surae, which limits the foot's ability to flex upwards (dorsiflexion).

Components of Best Management¶
The clinical course is generally favourable, with 80% to 90% of cases resolving within 12 months through non-operative measures.
First-Line (Non-Operative) Management:¶
• Patient Education and Activity Modification: Patients should be advised that the condition is self-limiting and should avoid walking barefoot or wearing flat shoes. Limiting prolonged weight-bearing activities is also recommended.
• Exercises: Plantar fascia-specific stretching and calf stretching are core components of treatment. Recent evidence also supports high-load strength training (e.g., single-leg heel raises with toes dorsiflexed), which can lead to a quicker reduction in pain and improved function.
• Mechanical Support: Low-dye taping provides short-term pain relief. Customised orthoses or shoe inserts have moderate-quality evidence for reducing pain intensity in the short term.
• Adjunctive Therapies: If initial measures fail, Extracorporeal Shockwave Therapy (ESWT) can be considered, as it may stimulate healing in chronic degenerative cases.

The clinical course is generally favourable, with 80% to 90% of cases resolving within 12 months through non-operative measures. This emphasizes the self-limiting nature of the condition and supports conservative management as first-line treatment.
Pharmacological and Injection Options:¶
• Medications: NSAIDs may provide symptomatic relief, though they do not address the underlying degenerative process.
• Injections: Corticosteroid injections can offer short-term pain relief (up to one month) but are less effective in the long term and carry a small risk of plantar fascia rupture. Other options include botulinum toxin or platelet-rich plasma (PRP), though evidence for these remains somewhat inconclusive.
Surgical Management:¶
Surgical intervention is reserved for a small subgroup (approximately 5%) of patients who have persistent, severe symptoms that have failed to respond to appropriate conservative management for at least 6 to 12 months.
• Procedures: Options include plantar fasciotomy (open or endoscopic), which involves releasing part of the fascia, and proximal medial gastrocnemius release (PMGR).
• Effectiveness: PMGR is increasingly recommended, particularly for patients with demonstrated gastrocnemius tightness, as it may offer better functional outcomes and higher patient satisfaction than traditional fasciotomy.
• Recovery: Endoscopic approaches typically allow for a faster recovery and return to normal activity compared to open surgery
