Posterior tibial tendon dysfunction, a common cause of adult acquired flatfoot, involves tendon weakening and arch collapse. Treatment progresses from non-operative measures to surgical interventions based on deformity stage.

Area of Science:

  • Orthopedics and Sports Medicine
  • Biomechanical Engineering
  • Podiatry

Context:

  • Posterior tibial tendon dysfunction (PTTD) is the leading cause of acquired flatfoot in adults.
  • It involves histological changes, tendon weakening, and compromised function, leading to arch collapse and pes planovalgus deformity.
  • Risk factors include female gender, obesity, and hypertension, with typical onset around age 40.

Purpose:

  • To review the pathophysiology, diagnosis, classification, and management of posterior tibial tendon dysfunction.
  • To outline the Johnson and Strom staging system for PTTD based on deformity and joint involvement.
  • To detail non-operative and operative treatment strategies tailored to each stage of PTTD.

Summary:

  • PTTD results from collagen fiber disruption, weakening the posterior tibial tendon and destabilizing the medial longitudinal arch.

  • Diagnosis relies on clinical and radiographic findings, with the Johnson and Strom classification guiding treatment.
  • Management ranges from conservative care (immobilization, orthotics) to surgical options like tendon transfer, osteotomies, fusions, and arthrodesis depending on PTTD stage.

    • Impact:

    • Provides a comprehensive overview of PTTD, aiding clinicians in accurate diagnosis and staged treatment planning.
    • Highlights the progression from conservative to surgical interventions based on disease severity.
    • Enhances understanding of PTTD management, potentially improving patient outcomes for acquired flatfoot deformities.
