“We are delighted to have implanted the first patient using Stryker’s Infinity Total Ankle System with Adaptis and Everlast technology as part of the UK post-market clinical study,” said Mr. Townshend. “This new technology marks the next step of the Infinity Total Ankle System which has already shown promising outcomes and survivorship for our patients with end stage ankle arthritis. We look forward to sharing the results of this clinical study.”

“Infinity with Adaptis builds on the legacy of the original Infinity Total Ankle, with a decade of clinical use. Recent publication data showed a 98.8% survivorship at two years of the original Infinity implant,¹ demonstrating its safety and efficacy as a low-profile prosthesis for surgeons treating end-stage ankle arthritis,” said Markus Ochs, vice president and general manager of Stryker’s European Trauma & Extremities business. “These initial procedures highlight Stryker's dedication to innovation and commitment through research, enhancing our collaboration with surgeons.”

The Infinity Total Ankle System consists of a titanium alloy tibial tray, cobalt chromium talar dome, and polyethylene insert and features a low-profile tibial implant design. The Adaptis 3D-printed total ankle implants² incorporate porous metal components strategically designed to act as a scaffold, facilitating boney ingrowth.^3* The Everlast highly cross-linked polyethylene inserts, blended with vitamin E, have been demonstrated to improve wear resistance.⁴ The interchangeability of the two talar options adds versatility to the system, designed for catering to diverse patient needs.

The system is optimized for efficiency⁴ through Prophecy Surgical Planning, which includes patient-specific instruments.
