    Area of Science:

    • Orthopedic surgery
    • Biomedical engineering

    Background:

    • Degeneration of the first metatarsophalangeal (MTP) joint causes pain and limits mobility.
    • Hallux rigidus is a common form of osteoarthritis affecting the MTP joint.

    Purpose of the Study:

    • To introduce and evaluate a novel prosthesis for resurfacing the first MTP joint.
    • To assess the clinical efficacy of this new surgical intervention.

    Main Methods:

    • Design and implantation of a resurfacing prosthesis for the first MTP joint.
    • Clinical evaluation of patient outcomes following the procedure.

    Main Results:

    • Satisfactory clinical results were observed in 16 out of 18 patients.
    • The prosthesis effectively addressed pain and degeneration in the treated joint.

    Conclusions:

    • The designed prosthesis offers a potentially effective treatment for painful, degenerated first MTP joints.
    • The procedure appears most beneficial for older patients diagnosed with hallux rigidus.
    • Longer follow-up periods are necessary to establish definitive long-term outcomes and opinions.
