Area of Science:

  • Biomechanics
  • Orthopedic research
  • Medical device development

Background:

  • Understanding ankle biomechanics is crucial for effective injury treatment.
  • Previous studies lacked reliable methods for measuring intra-articular ankle forces under dynamic conditions.
  • The validity of static force distribution data for dynamic ankle movements remained unconfirmed.

Purpose of the Study:

  • To characterize a novel electro-mechanical thin-membrane force transducer for intra-articular ankle use.
  • To validate the use of static loading methodologies for studying ankle force distribution.
  • To investigate ankle joint forces during static and dynamic dorsiflexion and plantarflexion.

Main Methods:

  • Developed and tested a novel thin-membrane force transducer for intra-articular application.

  • Assessed sensor performance in terms of linearity, reproducibility, and sensitivity to moisture and shear forces.
  • Implanted sensors in cadaveric ankles, applying axial loads and cycling through physiological ranges of motion under static and dynamic conditions.

    • Main Results:

    • The force transducer demonstrated reproducible linear responses and was insensitive to moisture and shear forces.
    • Medial and lateral malleolar-talar forces increased with dorsiflexion.
    • No significant difference was found between forces measured under static versus dynamic conditions, validating static methodologies.

    Conclusions:

    • The developed force transducer is suitable for intra-articular ankle measurements.
    • Static loading accurately reflects dynamic ankle force distribution, supporting its use in future research.
    • Dorsiflexion generates forces causing distal fibula rotation and lateral translation, providing new insights into ankle biomechanics.
