A Revision Knee Implant Alternative for Patients with Metal Sensitivities
WARSAW, Ind., March 7, 2025 /PRNewswire/ -- Zimmer Biomet Holdings, Inc. (NYSE and SIX: ZBH), a global medical technology leader, today announced U.S. Food and Drug Administration (FDA) 510(k) clearance of Persona® Revision SoluTion Femur, a revision knee implant component offering an alternative for patients with sensitivities to certain metals. The Persona Revision SoluTion Femur, part of the comprehensive Persona Revision Knee System, leverages a proprietary surface-hardening treatment designed to enhance wear performance,1,2 which offers surgeons an array of anatomic components, including tibial and femoral cones with various stem choices to address zonal fixation.
"We are pleased to expand our proprietary surface-hardening technology into the revision knee space with FDA clearance of the Persona Revision SoluTion Femur, the first metal alternative option for those with certain metal sensitivities," said Joe Urban, President, Knees at Zimmer Biomet. "We are proud to offer a total revision knee construct with no deliberate addition of the most common metal allergens (Nickel, Cobalt, & Chromium). Metal sensitivity is one of the potential causes of revision procedures, and the Persona Revision SoluTion Femur is yet another innovation that delivers on our commitment to solve the most meaningful challenges in musculoskeletal health."
Cutaneous metal hypersensitivity affects 10-15 percent of the general population, while prevalence in patients with metallic implants may be as high as 25 percent.3 Patients may experience an immunological reaction against metallic particles (ions) that are released as a result of implant wear or corrosion.4 When exposed to certain metals commonly used in metal knee implants such as nickel, cobalt and chromium, people with these hypersensitivities can experience an inflammatory response, pain and implant loosening that can require a total knee replacement revision procedure.5
The Persona Revision SoluTion Femur is made solely of a proprietary Tivanium® (Ti-6Al-4V) alloy with more than 17 years of clinical use.6 The alloy is treated with the Ti-Nidium Surface Hardening Process, which results in a strengthened material that demonstrates hardness, comparable to that of metal implants, with enhanced wear performance that provides resistance to particle release.2,7 The new revision femur is offered in standard and plus sizes to address flexion instability and soft tissue balancing while minimizing implant overhang.8,9
Persona Revision SoluTion Femur will be commercially available in the U.S. in Q3 2025.
