The First and Only Modular Stem Ankle System Anteriorly Inserted

restor3d, a leader in 3D-printed, personalized orthopedic solutions, today announced the full commercial availability of the Aeros™ Modular Stem System, an advancement in stemmed total ankle replacement designed to enhance implant stability, preserve bone, and improve surgical efficiency. The system follows a successful limited market release that began May 5, 2025, during which more than 250 procedures were completed across 50+ unique surgeons with strong feedback regarding intra-operative workflow and patient outcomes.

The Aeros Modular Stem System is now commercially available in the United States beginning April 2, 2026.

Part of the Kinos Total Ankle portfolio, the Aeros Modular Stem System introduces the first modular stem tibial implant designed to be implanted entirely through a standard anterior incision without bulky external hardware or violating the calcaneus and subtalar joint. By combining a familiar surgical exposure with stemmed fixation, the system enables surgeons to achieve enhanced stability while minimizing disruption to surrounding anatomy.

“Fixation has always been one of the most important drivers of long-term success in total ankle replacement, but historically that has required tradeoffs in exposure or bone preservation,” said Samuel Ford, MD, OrthoCarolina, and design team surgeon for the Aeros Total Ankle System. “The ability to place a modular stem through a standard anterior approach gives me the stability I want without increasing surgical morbidity. In practice it feels familiar, efficient, and reproducible, and my early patients have recovered very well.”

Built on restor3d’s proprietary TIDAL Technology™, the system incorporates 3D-printed tibial and talar implants with optimized porous architecture designed to support biological fixation and long-term osseointegration^1,2. The platform allows surgeons to select interchangeable articulation constructs and pair any tibial implant size with any flat-cut talar component, supporting flexibility in surgical philosophy while preserving bone through minimized resections. The system also features streamlined instrumentation and can be used with or without Axiom PSR™, restor3d’s fully metal patient-specific resection guides for total ankle replacement. Stemmed tibial implants have demonstrated significantly reduced odds of tibial and overall mechanical failure compared with low-profile tibial implants³.

“With Aeros, we focused on delivering fixation, flexibility, and efficiency in a single platform,” said Kurt Jacobus, CEO and Co-Founder of restor3d. “This system expands surgeon choice within the Kinos ankle portfolio while supporting consistent, reproducible outcomes for patients.”
