Technology & Products
Key Products
Klassic Knee System (modern universal femoral design, single-tray primary workflow); Klassic Knee Revision System with Universal Cone System; Klassic HD Hip System; Platform Hip / Platform Acetabular System; Aurum Technology (ballistically bonded titanium nitride surface); Klassic ONE instrumentation; PS-Max tibial insert.
Technological Advantage
Streamlined system architecture reducing inventory and instrument complexity; Aurum TiN surface for metal-sensitive patients; ASC-aligned economics (32% of 2026 YTD procedures in ASCs); compatibility with THINK Surgical TMINI robotic system. Additive manufacturing is outsourced to supply partners; specific printed components and processes are undisclosed.
Differentiation
Value Proposition
Efficiency by Design platform: hip and knee implant systems requiring a maximum of three instrument trays per procedure, cutting sterilization burden, storage cost and OR turnover time, suited to ambulatory surgery centers.
How They Differentiate
Fewer instrument trays and universal femoral design versus multi-tray, side-specific systems from large incumbents; cobalt-chrome reduction strategy via Aurum TiN surface; ASC-focused cost positioning.
Market & Competition
Target Customers
Orthopedic surgeons, hospitals and ambulatory surgery centers (ASCs) performing total joint arthroplasty in the United States.
