    Area of Science:

    • Biomaterials Science
    • Orthopedic Engineering
    • Polymer Science

    Background:

    • Ligament injuries often require surgical replacement.
    • Development of synthetic materials for ligament prostheses is ongoing.
    • Evaluating mechanical properties under physiological conditions is crucial.

    Purpose of the Study:

    • To assess the suitability of polymer materials as potential ligament replacements.
    • To determine which materials meet the mechanical demands of physiological loading.

    Main Methods:

    • Mechanical testing of approximately 50 polymer specimens.
    • Static and dynamic testing protocols were employed.
    • Testing conditions were designed to simulate physiological environments.

    Main Results:

    • Significant variations in mechanical properties were observed among tested polymers.
    • Only one specific material, an entangled polyester-flat-ligament, demonstrated adequate performance.
    • The chosen material satisfied the established requirements under simulated physiological conditions.

    Conclusions:

    • Entangled polyester-flat-ligaments show promise as a viable option for polymer ligament replacement.
    • Further research and development may be needed for other polymer candidates.
    • This study provides critical data for the selection of materials in orthopedic applications.
