Central Indiana Orthopedics (CIO) is proud to be the first orthopedic group in Indiana to offer the Triathlon® Gold knee replacement, with the state’s first procedure performed on Friday, January 23, 2026, at CIO Fishers Outpatient Surgery Center. This milestone marks another exciting step forward in CIO’s commitment to innovation – building on our history as the region’s first orthopedic practice to adopt and implement Mako SmartRobotics™ technology for hip and knee replacement. The Triathlon® Gold knee implant is now available at Central Indiana Orthopedics Fishers and Muncie Outpatient Surgery Centers.
Metal Sensitive Patients Can Now Choose Mako Robotic-Assisted Surgery
Patients with metal sensitivities have long had implant options, but these implants were not compatible with the Mako SmartRobotics™ system. Because of this, patients with metal sensitivity concerns could not take advantage of Mako’s advanced surgical precision and personalized planning.
The arrival of Triathlon® Gold changes that.
Because Triathlon® Gold is part of the same implant family CIO already uses with Mako joint replacements, patients can now receive:
- A metal sensitivity–friendly implant designed without the deliberate addition of nickel, cobalt, or chromium
- The accuracy, consistency and personalized alignment planning that Mako SmartRobotics™ provides
This means metal sensitive patients no longer must choose between implant compatibility and robotic-assisted precision – they can have the best of both worlds within a single, trusted system.
Precision and Peace of Mind
Triathlon® is the long‑standing Stryker knee replacement system CIO surgeons have used for years, especially during robotic‑assisted procedures. With the introduction of Triathlon® Gold, we can now maintain:
- the same trusted implant design
- the same proven outcomes
- the same robotic precision our team has used in more than 4,000 robotic procedures
All provided while adding this new metal sensitivity‑friendly version of that implant.
For patients, this means greater confidence in both their implant and their surgical experience.
Triathalon® Gold Benefits and Who’s a Candidate
Triathlon® Gold provides a hypoallergenic alternative that is now offered by the robotic technology that CIO has trusted since 2016. As a result, patients may experience:
- Reduced concern about metal‑related reactions
- Access to Mako robotic‑assisted surgery even with metal sensitivities
- Care tailored to individual health needs
- A seamless experience using the same implant system trusted by CIO in thousands of knee replacement procedures
This implant may be an excellent option for patients who:
- Have documented metal allergies
- Experience reactions to jewelry or other metals
- Previously postponed knee replacement due to sensitivity concerns
- Prefer a non‑cobalt‑chrome option for peace of mind
- Experienced unexplained symptoms after a previous implant
