    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering

    Background:

    • Surface replacement hip arthroplasty is an alternative for select younger patients requiring hip replacement.
    • Accurate patient selection and diagnosis are crucial due to a narrow range of indications.

    Purpose of the Study:

    • To evaluate the outcomes and complications of surface replacement hip arthroplasty in a cohort of younger patients.
    • To identify factors influencing the success of surface replacement procedures.

    Main Methods:

    • A follow-up study was conducted on 44 patients who underwent surface replacement hip arthroplasty.
    • Patient data including pain levels, motility, complications, and surgical approach were analyzed over a 10-month to 4-year period.

    Main Results:

    • The study observed a low rate of loosening (5%) and no other severe complications in the 44 patients.
    • Significant improvements were noted, with 89% of patients reporting no post-operative pain and a distinct improvement in motility.
    • The Watson-Jones surgical approach appeared to result in fewer paraarticular calcifications compared to the Wagner approach.

    Conclusions:

    • Surface replacement hip arthroplasty can be a successful procedure for carefully selected younger patients, offering significant pain relief and improved function.
    • Conditions like avascular necrosis are not suitable for surface replacement, and inflammatory diseases (e.g., rheumatoid arthritis) may increase complication risks, particularly with steroid use.
    • Surgical approach, specifically the Watson-Jones method, may influence outcomes by reducing complications like calcifications.
