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.
High-Purity Titanium Construction
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.
Advanced Polyethylene Articulation
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.
Modular Component Range
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.
Versatile Fixation Options
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.
Clinical Indications
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.
Contraindications
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.
