Area of Science:

  • Orthopedic prosthetics
  • Rehabilitation medicine
  • Biomechanical engineering

Background:

  • Below-knee amputations often present with concurrent knee flexion contractures, complicating prosthetic fitting.
  • Standard bent-knee prostheses are functionally limited and do not address contracture improvement.

Observation:

  • A case report details an alternative prosthetic fitting for patients with below-knee amputation and knee flexion contracture.
  • The novel prosthesis was evaluated for functional outcomes and therapeutic effects on contracture.

Findings:

  • The alternative prosthesis demonstrated improved functional outcomes compared to the standard bent-knee prosthesis.
  • The new prosthetic approach also showed therapeutic benefits by reducing the patient's knee-flexion contracture.

Implications:

  • This approach offers a potentially superior solution for managing below-knee amputations with knee flexion contractures.
  • It highlights the possibility of integrating therapeutic benefits into prosthetic device design for improved patient outcomes.
