The Aeros Modular Stem, the latest addition to the Kinos Total Ankle family, represents the first and only anteriorly inserted modular stem tibial implant available for Total Ankle Replacement (TAR). Cleared by the FDA for both primary and revision indications, the system enters a limited market release throughout 2025, with full commercial launch anticipated in 2026.

“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.”

Designed for efficiency, versatility, and ease of use, the Aeros Modular Stem requires just three trays of procedure-specific instruments, compared to up to seven trays for competitive systems. The implant is inserted through a standard anterior TAR incision, avoiding violation of the heel, calcaneus, or subtalar joint—a key differentiator from other intramedullary systems. The refined instrumentation provides a hands-free working area for streamlined tibial canal preparation, with coupled and standalone Patient Specific Resection (PSR™) Cut Guides providing greater intraoperative flexibility, particularly in complex deformity cases. Restor3D’s proprietary TIDAL Technology on all tibial and talar implants provides scientifically proven, research backed osseointegration potential, further emphasizing the role of the Kinos Total Ankle System in advancing total ankle arthroplasty.

The system is fully compatible with all existing Kinos Flat Cut Talus and bearing components, including its interchangeable Anatomic and Range articulations. In simulator testing, both articulating bearings demonstrated substantially improved polyethylene wear performance, with 200% less wear than Competitor A and 400% less than Competitor B¹. Competitors A and B were selected for comparison due to their length of time in the market and considerable clinical follow-up data presented in the literature. This advancement reflects the biomechanically accurate design of Kinos and directly addresses the growing demand for longer-lasting implants as survivorship rates improve.

Early retrospective studies are underway to validate an anticipated 30% reduction in operative time versus traditional stemmed systems—a meaningful objective given published data by Gross et al.², which links every 15-minute increase in TAR operative time with a 10% increase in complications, 33% increase in wound dehiscence, and 16% increase in reoperations.

“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.”
