restor3d has fully launched its Aeros modular stem system, a stemmed total ankle replacement designed to boost implant stability, preserve bone, and improve surgical efficiency.

This follows a limited market release that began May 5, 2025, where over 250 procedures were completed by 50+ unique surgeons with strong feedback about intra-operative workflow and outcomes.

The Aeros modular stem system is part of the Kinos total ankle portfolio. It introduces the first modular stem tibial implant designed to be implanted entirely through a standard anterior incision without bulky external hardware or violation of the calcaneus and subtalar joint.

It combines a familiar surgical exposure with stemmed fixation so surgeons can achieve better 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.”

The system leverages 3D-printed tibial talar implants with optimized porous architecture designed to support biological fixation and long-term osseointegration. The platform allows selection of interchangeable articulation constructs and pairing of any tibial implant size with any flat-cut talar component.

The Aeros modular stem system also touts streamlined instrumentation and can be used with or without the Axion PSR fully metal patient-specific resection guides for total ankle replacement.

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

In February, the company began full commercial launch of the Ossera AFX ankle fusion cage system, which is engineered for complex ankle fusion cases.
