High-Purity Titanium Constructs for Total Knee Arthroplasty (TKA)

The CytroFIX® Knee Replacement System by Cytronics (an INVAMED orthopedic division) is designed to address a wide spectrum of knee pathologies, including osteoarthritis, rheumatoid arthritis, post-traumatic degeneration, and revision arthroplasty scenarios. Utilizing high-purity titanium components for optimal biocompatibility and corrosion resistance, this system combines state-of-the-art materials with an anatomically contoured design, aiming to restore functionality and reduce postoperative complications in total knee replacement (TKR).

Anatomically Inspired Design
  • Femoral and tibial components are contoured to closely replicate native knee joint geometry.
  • Facilitates efficient load distribution, promoting more natural kinematics and reduced stress on surrounding tissues.
  • Titanium alloy (e.g., Ti-6Al-4V ELI) in tibial trays or certain femoral components (where design permits) ensures excellent strength-to-weight ratio and superior corrosion resistance.
  • Minimizes the risk of allergic reactions while enhancing bone integration, especially around the porous or press-fit surfaces.
  • UHMWPE (Ultra High Molecular Weight Polyethylene) or X-linked polyethylene inserts provide low wear and maintain stable joint articulation.
  • Optimized tibial inserts reduce potential backside wear and assure long-term durability.
  • Multiple femoral sizes (right and left), tibial baseplates, and polyethylene thicknesses accommodate patient-specific anatomy.
  • Optional patella resurfacing implants (onlay or inlay) available for comprehensive joint restoration when clinically indicated.
  • Cemented: Polymethyl methacrylate (PMMA) fixation for secure, immediate stability.
  • Cementless (Press-Fit): Porous or hydroxyapatite-coated surfaces promoting biological ingrowth.
  • Hybrid Techniques: Combining cemented and cementless elements based on bone quality and surgeon preference.
  • End-stage degenerative joint disease (e.g., osteoarthritis, rheumatoid arthritis), traumatic arthritis, or irreparable meniscal/ligament damage requiring TKA.
  • Revision scenarios where prior implants have loosened or failed, provided sufficient bone stock for stable fixation.
  • Active infection in or around the knee joint, severe untreated osteoporosis, or systemic conditions that preclude elective joint replacement.
  • Patients lacking the ligamentous structures or neuromuscular control needed for stable TKA, unless compensated by a constrained or hinged design.
