Many surgeons use low-cost hip implants to reduce total hip arthroplasty costs. A study found these implants perform comparably to more expensive options, indicating cost control is a widespread practice.

Area of Science:

  • Orthopaedic Surgery
  • Biomedical Engineering
  • Health Economics

Background:

  • Total hip arthroplasty (THA) costs are a significant concern.
  • Strategies to reduce implant expenses include using remaindered, older, discounted, or specifically designed low-cost implants.
  • The prevalence and efficacy of these cost-containment measures require investigation.

Purpose of the Study:

  • To determine the prevalence of using low-cost prostheses in total hip arthroplasty.
  • To assess the clinical performance of a generic hip implant compared to standard prostheses.
  • To understand the current practices regarding cost containment in THA.

Main Methods:

  • Survey distributed to members of The Hip Society and Canadian orthopaedic surgeons.

  • Analysis of questionnaire responses regarding the use of low-cost implants.
  • Clinical trial evaluating a generic hip implant in 150 patients over a minimum of two years.

    • Main Results:

    • 73% of surveyed surgeons reported using low-cost prostheses for specific THA indications.
    • No standardized policy for cost containment or definition of 'low cost' was identified.
    • The generic hip implant demonstrated comparable hip score improvements and complication rates to more expensive alternatives.

    Conclusions:

    • The use of low-cost prostheses is a common practice among orthopaedic surgeons for total hip arthroplasty.
    • Cost control through prosthetic selection is a widespread strategy in arthroplasty.
    • Generic hip implants show clinical compatibility, suggesting a viable option for cost reduction.
