    Hip resurfacing arthroplasty (HRA) is a bone-conserving alternative to total hip arthroplasty (THA) for young, active individuals with advanced hip disease.

    Survivorship rates after Birmingham Hip Resurfacing are 96.5% for men and 87.0% for women at 20 years, decreasing to 89.5% and 66.9% by 25 years.

  • 3

    Female sex, smaller component size, and developmental dysplasia of the hip (DDH) are identified as risk factors for HRA failure.

  • 4

    The study categorized hips by etiology as Primary OA, DDH, or Non-OA, with avascular necrosis (AVN) evaluated separately.

  • 5

    Long-term outcomes of HRA require comprehensive evaluation, including serum metal-ion measurements and MARS-MRI.
