restor3d releases Aeros Modular Stem System for total ankle replacement
Anterior insertion design eliminates need for external hardware or calcaneal violation
Personalized orthopedic solutions company restor3d has released the Aeros Modular Stem System for full commercial availability, completing a limited market launch that began in May 2025, during which more than 250 procedures were performed across more than 50 surgeons.
The system, part of the company’s Kinos Total Ankle portfolio, is described as the first modular stem tibial implant designed to be inserted entirely through a standard anterior incision, without bulky external hardware or disruption to the calcaneus and subtalar joint.
The design combines anterior surgical exposure with stemmed fixation, which the company stated allows surgeons to achieve greater implant stability while minimizing disruption to surrounding anatomy.
Surgical design and fixation approach
“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.”
The system is built on restor3d’s TIDAL Technology platform and incorporates 3D printed tibial and talar implants with porous architecture intended to support biological fixation and long-term osseointegration.
Surgeons can select interchangeable articulation constructs and pair any tibial implant size with any flat-cut talar component. The system is compatible with or without Axiom PSR, restor3d’s patient-specific resection guides for total ankle replacement.
Clinical data presented by the company indicated that stemmed tibial implants show significantly reduced odds of tibial and overall mechanical failure when compared with low-profile tibial implants.
“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.”
