This workshop explored the clinical use of metal-on-metal bearings in total hip arthroplasty. Consensus statements were developed considering past performance, clinical data, and the current environment.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Biomedical Engineering

Background:

  • Metal-on-metal bearings were previously used in total hip replacements but faced challenges.
  • Understanding the historical performance and current considerations is crucial for potential reintroduction.

Purpose of the Study:

  • To convene experts to discuss the reintroduction of metal-on-metal bearings in total hip arthroplasty.
  • To develop consensus statements based on current scientific understanding and clinical practice.

Main Methods:

  • A workshop format brought together approximately 100 researchers, clinicians, and industry representatives.
  • Discussions covered the interpretation of past performance, clinical, tribologic, and biologic factors.
  • Consensus statements were formulated based on presentations, literature, expert experience, and the current environment.

Main Results:

  • The state of the art interpretation of metal-on-metal total hip replacement performance was presented.
  • Clinical, tribologic, and biologic considerations of all-metal bearings were discussed.
  • Consensus statements were developed addressing the complex factors influencing metal-on-metal bearing use.

Conclusions:

  • The workshop provided a critical forum for evaluating metal-on-metal bearings in total hip arthroplasty.
  • Consensus was reached by integrating diverse scientific, clinical, and industry perspectives.
  • The developed statements offer guidance on the potential clinical use of these bearings.
