U.K. National Joint Registry Analysis of Zimmer Biomet Trabecular Metal Cups

By Julie A. Vetalice

Zimmer Biomet announced positive outcomes associated with use of Trabecular Metal™ Cups in >9,500 revision hip arthroplasty patients, based on data from the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man. Trabecular Metal Cups were associated with lower infection rates and a significant reduction in subsequent hip revision rates.

Specifically, independent analysis* demonstrated:

  • Trabecular Metal Cups used in revision total hip arthroplasty (THA) were shown to be 21% less likely to be additionally revised due to infection.
  • For high-risk patients with a first revision indication being infection, Trabecular Metal Cups appeared to be 35% less likely to be additionally revised for infection. (Due to the limited sample size, this has not reached statistical significance)
  • Trabecular Metal Cups used in revision THA were shown to be 11% less likely to be additionally revised for any reason

The NJR report retrospectively analyzed outcomes related to 9,573 revision procedures using cementless Trabecular Metal Cups and 30,452 revisions using non-Trabecular Metal cementless cups, from April 2003 through July 2015.

*Statements were not evaluated by FDA for Zimmer Biomet Trabecular Metal Cups, and do not alter cleared indications for use.
