Stryker Unveils Triathlon Gold — First 3D Printed Femoral Component With Titanium Nitride Surface for Metal-Sensitive Patients

A New Era for 3D Printed Orthopaedic Implants

Stryker, one of the worlds largest medical device companies, has unveiled its latest 3D printed orthopaedic implant at the American Academy of Orthopaedic Surgeons (AAOS) 2026 Annual Meeting. The new Triathlon Gold represents the companys first commercially available additively manufactured femoral component, marking a significant milestone in personalized medical implant technology.

Designed for Metal-Sensitive Patients

The Triathlon Gold was specifically developed for patients with metal sensitivity concerns — a growing demographic in joint replacement surgery. The 3D printed implant features a Titanium nitride (TiN) surface coating that provides superior scratch resistance compared to competitive surfaces while delivering long-term durability and fixation.

"With more than 20 years of proven outcomes, the Triathlon system has set a high standard in knee replacement," said Lisa Kloes, vice president and general manager of Strykers Knee business. "Triathlon Gold represents the next evolution of that legacy — solutions shaped by customer insight and designed to meet the evolving needs of patients."

Triathlon MS Insert Also Launched

Alongside Triathlon Gold, Stryker introduced the Triathlon Media Stabilised (MS) Insert — an advancement in the Triathlon Total Knee System. This device allows customers to leverage the advantages of Mako SmartRobotics and Triathlon Cementless technologies while providing enhanced stability for Triathlon primary knee patients and more natural rotational kinematics.

3D Printings Role in Medical Innovation

The use of additive manufacturing in orthopaedic implants allows for complex geometric designs that traditional manufacturing methods cannot achieve. The lattice structures possible with 3D printing can be tailored to match the bone density profile of individual patients, promoting better osseointegration and reducing stress shielding.

Stryker has been a pioneer in medical 3D printing, and the Triathlon Gold continues this tradition by combining the design freedom of additive manufacturing with advanced surface technologies.

As the medical device industry continues to evolve, Stryker is expanding capabilities across orthopaedic specialties. "Surgeons and patients are seeking more solutions, and these innovations are designed to do just that — helping patients get back to the activities they love," added Katherine Truppi, President of Strykers Joint Replacement division.
