    Summary

    This study investigated cefuroxime antibiotic levels in bone cement for hip and knee replacements. Results show over 95% of the antibiotic remains in the cement, offering potential infection prophylaxis.

    Area of Science:

    • Orthopedic Surgery
    • Infectious Disease Prevention
    • Pharmacokinetics

    Background:

    • Total hip and knee replacements are susceptible to post-operative infections.
    • Antibiotic-loaded bone cement is a common strategy to prevent surgical site infections.
    • Cefuroxime is a widely used antibiotic for surgical prophylaxis.

    Purpose of the Study:

    • To quantify the elution and retention of cefuroxime in CMW bone cement after total joint arthroplasty.
    • To determine the proportion of cefuroxime remaining in bone cement for sustained prophylactic effect.

    Main Methods:

    • Patients undergoing hip or knee replacement received CMW bone cement with added cefuroxime.
    • Cefuroxime concentrations were measured in serum, wound drainage fluid, urine, and surplus bone cement.
    • Assays were performed within the first week post-operation.

    Main Results:

    • Less than 5% of the administered cefuroxime was recovered in urine, serum, and drainage fluid.
    • Approximately 95% of the cefuroxime remained within the bone cement.
    • This indicates minimal systemic absorption and significant retention in the cement.

    Conclusions:

    • CMW bone cement with cefuroxime demonstrates high retention of the antibiotic.
    • The substantial amount of cefuroxime remaining in bone cement suggests a prolonged local prophylactic effect against infection.
    • This formulation holds promise for reducing infection rates in total joint arthroplasty.
