U.S.-based company restor3D has announced the market launch of its Aeros Modular Stem Total Ankle System. The first five procedures using the new system were performed on May 5, 2025, at the OrthoCarolina Center under the direction of foot and ankle surgeons Dr. Kent Ellington and Dr. Samuel Ford. The implant system features a modular design that can be individually adapted to the patient’s anatomy using 3D printing technology.
The Aeros Modular Stem is the first tibial modular stem for Total Ankle Replacement (TAR) to be implanted via an anterior surgical approach. This method avoids interference with the heel bone and subtalar joint, thereby reducing the risk of additional soft tissue damage.
“We are exhilarated to see this system come to life in the OR with such a strong start,” said Dr. Samuel Ford. “The streamlined instrumentation and thoughtful design of the Aeros Modular Stem made for an efficient intraoperative experience, and it opens new doors for both primary and complex revision ankle arthroplasty cases.”
A core feature of the system is its surgical efficiency: only three trays of procedure-specific instruments are required, a significant simplification compared to conventional systems that often need up to seven trays. Additionally, the combination of standardized and patient-specific resection guides (PSR Guides) enables flexible and precise alignment, especially in cases involving complex deformities.
The implants are coated with restor3D’s proprietary TIDAL surface technology, which is intended to promote improved osseointegration. In simulated wear tests, the polyethylene bearings used in the system demonstrated significantly lower wear rates compared to established competitor products. Retrospective studies are currently underway to assess clinical performance, particularly the potential reduction in surgical time.
“The Kinos Modular Stem system combines modularity, versatility, and simplicity in a way the TAR market has long needed,” added Dr. Ford. “This is a platform I’m confident will appeal to both experienced and new users alike.”
