In this episode of The Sports Docs Podcast, Dr. Ashley Bassett and Dr. Catherine Logan are joined by Dr. Arianna Gianakos, orthopedic foot and ankle surgeon at Yale University, to discuss one of the most common causes of heel pain in athletes and active adults—plantar fasciitis.

The conversation explores the underlying pathology of plantar fasciitis, risk factors that contribute to its development, and the latest evidence supporting conservative treatment strategies. Dr. Gianakos shares practical pearls on patient evaluation, imaging, bracing, orthotics, stretching programs, and physical therapy, helping clinicians navigate an often frustrating condition for both patients and providers.

Highlights

Understanding Plantar Fasciitis

•  Plantar fasciitis is more accurately described as a degenerative fasciosis rather than an inflammatory condition 
•  Histologic studies demonstrate: 
  •  Collagen disorganization 
  •  Microtears 
  •  Minimal inflammatory changes 
•  Repetitive overload at the plantar fascia origin leads to structural degeneration and loss of elasticity 

Why Does Morning Pain Occur?

•  Classic "first-step pain" results from overnight shortening of the plantar fascia 
•  Initial weightbearing produces a sudden stretch and reloading of the tissue 
•  Pain often improves with activity before worsening again later in the day 

Clinical Evaluation & Imaging

•  Diagnosis is primarily clinical 
•  Key examination findings include: 
  •  Point tenderness at the medial calcaneal tubercle 
  •  Pain with plantar fascia stretching 
  •  Assessment of ankle flexibility and calf tightness 
•  Imaging considerations: 
  •  Ultrasound can demonstrate plantar fascia thickening 
  •  MRI may be useful in chronic or refractory cases 

Risk Factors for Plantar Fasciitis

Recent literature suggests several important risk factors:

•  Higher body mass index (BMI) 
•  Increased body mass 
•  Increased ankle plantarflexion range of motion 

Surprisingly, some traditionally cited factors may not be as influential as previously believed:

•  Foot structure 
•  Limited ankle dorsiflexion 

These findings suggest that load-related factors may play a larger role than static foot alignment.

Bracing & Orthotic Management

Night Splints

•  Particularly beneficial in chronic plantar fasciitis (>6 months) 
•  Help maintain plantar fascia length overnight 
•  Can reduce morning pain and stiffness 

Daytime Orthotics

•  Heel cushions 
•  Arch supports 
•  Functional plantar fascia braces 

Custom vs. Prefabricated Orthotics

•  Both are effective for pain relief and symptom improvement 
•  Studies show similar short-term outcomes 
•  Prefabricated orthotics are often a cost-effective first-line option 
•  Custom orthotics may offer improved durability and individualized support 

Exercise & Physical Therapy

Home Exercise Programs

•  Convenient and cost-effective 
•  Can achieve outcomes comparable to formal physical therapy when patients are compliant 

Physical Therapy Benefits

•  Accountability and supervised progression 
•  Access to additional modalities: 
  •  Manual therapy 
  •  Dry needling 
  •  Shockwave therapy 
  •  Soft tissue mobilization 

Key Exercises for Plantar Fasciitis

Evidence-based interventions include:

•  Plantar fascia-specific stretching 
•  Gastrocnemius stretching 
•  Intrinsic foot muscle strengthening 

Research suggests plantar fascia-specific stretching may be superior to generalized stretching programs for symptom improvement.

Key Takeaways

•  Plantar fasciitis is primarily a degenerative condition rather than an inflammatory process. 
•  Morning pain results from overnight shortening and reloading of the plantar fascia. 
•  Increased body mass and mechanical loading appear to be major contributors to symptom development. 
•  Night splints, heel cushions, and arch supports remain valuable first-line treatments. 
•  Prefabricated orthotics often perform as well as custom devices while reducing cost. 
•  Both supervised physical therapy and home exercise programs can be effective when patients are compliant. 
•  Plantar fascia-specific stretching and calf flexibility remain foundational components of treatment.
