Zimmer Biomet Holdings Inc. announced positive outcomes associated with the use of its trabecular metal cups for revision hip arthroplasty.
According to a recent report from the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man, use of trabecular metal cups correlated with lower infection rates and a significant decrease in the need for subsequent hip revision. According to a Zimmer Biomet press release, the NJR retrospectively evaluated outcomes of 9,573 revision surgeries performed with cementless trabecular metal cups and 30,452 revision surgeries performed with non-trabecular metal cementless cups.
“Infection, implant loosening, pain and dislocation are the most common reasons for revision joint replacement surgery,” Zimmer Biomet Group President of Joint Reconstruction, Dan Williamson, said in the release. “Our trabecular metal acetabular devices are designed to meet the long-term performance needs of hip implant patients. The NJR report reinforces their value in significantly reducing hip revision rates in a large clinical patient population and yielding better outcomes in comparison to traditional non-trabecular metal implants.”
Results from the NJR noted revision total hip arthroplasties (THAs) performed with trabecular metal cups were 21% less likely to undergo re-revision due to infection, and the release noted, “For high-risk patients with a first revision indication being infection, trabecular metal cups appear to be 35% less likely to be re-revised for infection. Due to the limited sample size, this has not reached statistical significance.”
When the cups were used for revision THA, the release noted these procedures were 11% less likely to be revised for any reason.
