    Area of Science:

    • Orthopedic Surgery
    • Biomaterials Science
    • Infectious Disease Prevention

    Background:

    • Postoperative infection remains a significant complication in total hip replacement (THR).
    • Ensuring a stable, long-term cement-bone interface is crucial for prosthetic longevity.
    • Current approaches require re-evaluation to address these critical aspects.

    Purpose of the Study:

    • To highlight the importance of extreme operating room sterility in THR.
    • To investigate the combination of enhanced sterility with antibiotic prophylaxis.
    • To demonstrate the long-term stability of the cement-bone interface in THR.

    Main Methods:

    • Review of radiologic data from THR cases with a minimum of 12.5 years follow-up.
    • Presentation of radiographic evidence of acrylic cement in the femur after 20 and 21 years of load bearing.
    • Emphasis on meticulous surgical techniques to achieve optimal cement fixation.

    Main Results:

    • Radiographic evidence supports the achievement of perfect cement-bone interfaces after 12.5 years.
    • Examples demonstrate the durability of acrylic cement in the femur under load-bearing conditions for over 20 years.
    • The study reinforces the viability of maintaining interface integrity.

    Conclusions:

    • Extreme operating room sterility, combined with antibiotic prophylaxis, is essential for reducing infection risk in THR.
    • A stable, long-term cement-bone interface is achievable with meticulous technique.
    • These factors are paramount for the future success of total hip replacement procedures.
