Built on TRUST.
Based on decades of experience, Waldemar Link created a comprehensive knee system that covers all aspects of modern total knee arthroplasty from cruciate retaining, posterior stabilized to stemmed revision variants with high-end user-friendly instrumentation.
The LinkSymphoKnee is a complete system for primary total knee replacement to revision solutions.
The LinkSymphoKnee has a wide range of implant sizes with 14 femoral and 10 tibial sizes and provides a 2up - 2down compatibility between femoral and tibial components. The components are made from high-end materials. Thus, all variants are additionally available with LINK PorEx surfaces which reduce the release of metal ions. All poly components, such as articular surfaces and patella, are available either in UHMWPE or in E-dur Polyethylene (highly cross-linked PE with antioxidant vitamin E). The system comes with state-of-the-art streamlined instrumentation, which allows an optimal surgical worflow and is highly adjustable to the user‘s needs.
COMPLETE SYSTEM FROM PRIMARY TO REVISION
The LinkSymphoKnee system is a fixed bearing system with different constraint levels, such as cruciate ligament conserving (CR), cruciate ligament replacing (PS and PS+) and revision options (CCK). The high compatibility between the components provides a high intraoperative flexibility. All components are available as LINK PorEx versions.

HIGH-END MATERIALS
E-DUR
All CR, PS, PS+, & CCK Poly inserts are available in UHMWPE and E-DUR, which is Vitamin E infused cross-linked polyethylene1.
In the production of Vit-E plateaus, vitamin E is used as an antioxidant in order to protect the material by neutralizing the free radicals created by highly crosslinking. The product's mechanical properties and biocompatibility are preserved 2,3,4,5.
Highly Cross-Linked by irradiation
Improved wear resistance for delamination and abrasion demonstrated in in vitro testing.6,7
Vitamin-E-Doped
Stabilizing of UHMWPE by enrichment with Vitamin E respectively synthetic available product alpha-tocopherol. Reduction of free radicals improves durability8
LINK PorEx
All LinkSymphoKnee metal components are available with the LINK PorEx ceramic-like surface.
LINK PorEx serves as an Ion shield, as a ceramic coating significantly reduces
the metal ion release of the underlying metal substrate9.
• Decreased metal ion release9
• Increased scratch resistance10
• Lower friction coefficient10
• Increased fatigue strength10
• Increased hardness9
STREAMLINED INSTRUMENTS
The LinkSymphoKnee System includes streamlined, lightweight and ergonomic instrument sets, allowing for straightforward workflow and high reproducibility. Multi-purpose instruments and elaborate trial components help to reduce the amount of instruments and number of trays, thus enhancing the intra-operative handling and flexibility.

FAQs
- The gradually decreasing flexion radius (J-curve) reduces mid-flexion instability
- Smooth transition in sagittal curvature
- Higher congruency in extension
- PS Post and Cam mechanism engagement at 60° flexion
- PS Post and Cam mechanism limits posterior tibia translation and facilitates femoral rollback
- Concave Cam design increases surface contact between Cam and Post and reduces pressure peaks.
- Homogenous growth of 3 mm from size to size size in anterior direction.
- Posterior aspect constant as usual in all posterior referencing systems
- The anterior Patella Flange angle amounts to 4,5°
- The thickness is constant and amounts to 9 mm in all Femoral Components
- One spacer block is required to assess the extension and flexion gap.
