The Elite Plus total hip arthroplasty demonstrated excellent clinical outcomes, with improved Harris Hip Scores and minimal femoral subsidence over five years. This cemented femoral component shows results comparable to the Charnley hip.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Clinical Research

Background:

  • Total hip arthroplasty (THA) is a common procedure for hip joint diseases.
  • Evaluating the long-term performance of cemented femoral components is crucial for patient outcomes.
  • The Elite Plus cemented femoral component was introduced to improve THA efficacy.

Purpose of the Study:

  • To prospectively evaluate the clinical and radiological outcomes of the Elite Plus cemented femoral component in primary total hip arthroplasty.
  • To compare the five-year results of the Elite Plus hip arthroplasty with established benchmarks, such as the Charnley hip.

Main Methods:

  • Prospective study of 200 consecutive primary total hip arthroplasties using Elite Plus cemented femoral components.
  • Clinical evaluation using the Harris Hip Score (HHS) preoperatively and at five years.

Related Experiment Videos

  • Radiographic assessment including measurement of femoral subsidence at five years.

    • Main Results:

    • Mean HHS improved significantly from 39.3 preoperatively to 89.6 at five years.
    • Mean femoral subsidence was 1.40 mm at five years.
    • Low annual re-operation rate of 0.2% with no revisions for aseptic loosening.

    Conclusions:

    • The Elite Plus cemented femoral component achieved favorable clinical and radiological outcomes at five years.
    • Results are comparable to historical data from the Charnley hip, suggesting good long-term performance.
    • The study supports the efficacy of the Elite Plus hip arthroplasty in primary THA procedures.
