    This study presents a novel socket design for through-knee amputations, improving comfort and fit for bulbous stumps. The manufacturing technique ensures optimal prosthetic socket performance and patient satisfaction.

    Area of Science:

    • Prosthetics and Orthotics
    • Biomedical Engineering
    • Rehabilitation Medicine

    Background:

    • Through-knee stumps present unique challenges due to their bulbous shape and end-bearing capabilities.
    • Existing socket designs often inadequately address the specific anatomical and functional needs of through-knee amputees.
    • A specialized socket design is crucial for optimizing comfort, function, and cosmesis in this patient population.

    Purpose of the Study:

    • To describe a specialized socket design and manufacturing technique for through-knee amputation stumps.
    • To detail the requirements and fabrication process for an effective through-knee prosthetic socket.
    • To evaluate the comfort and cosmetic outcomes of the proposed socket design based on extensive clinical experience.

    Main Methods:

    Related Experiment Videos

  • Development of a socket design specifically for the bulbous morphology of through-knee stumps.
  • Detailed description and illustration of a manufacturing technique, emphasizing negative plaster mold quality.
  • Application of the double-wall technique, typically used for below-knee sockets, adapted for through-knee applications.

    • Main Results:

    • The described socket design accommodates the unique shape and end-bearing qualities of through-knee stumps.
    • The manufacturing technique, utilizing a high-quality plaster mold and double-wall construction, yields effective prosthetic sockets.
    • Clinical experience with 290 prostheses over 14 years demonstrates the socket's ability to provide significant comfort and cosmesis.

    Conclusions:

    • The presented socket design and manufacturing method offer a superior solution for through-knee amputees.
    • This technique provides enhanced comfort and cosmetic appearance without incurring additional costs.
    • The findings support the adoption of this specialized socket approach for improved patient outcomes in through-knee prosthetics.
