Choosing a Bearing Material for Hip Arthroplasty.

The authors discuss a report within the issue, ‘‘Comparison of Ten-Year Survivorship of Hip Prostheses with Use of Conventional Polyethylene, Metal-on-Metal, or Ceramic-on-Ceramic Bearings," by Ingrid Milošev and colleagues. The study looked at complications such as aseptic loosening, component fracture, and osteolysis requiring reoperation. It is argued that the study should have also considered impingement of acetabular components, adverse tissue reaction, and the preferences of surgeons.
