Excellently adapted: The TrabecuLink FlexiCones
directLINK 2/2020
LINK's TrabecuLink Femoral and Tibial Cones provide solid anchorage in at least two of three zones.* They are used for reinforcement in cases of metaphyseal and diaphyseal bone defects or bone loss, and thus for stabilization in the distal femur and proximal tibia.

The latest generation of LINK Femoral and Tibial Cones also features a proven titanium alloy, ergonomic instruments and a simple surgical technique. Here is an overview.
The Femoral or Tibial Cone must reinforce the metaphyseal or diaphyseal medullary space of the distal femur or proximal tibia and adequately fill the bone cavity. In addition, the cones must ensure a secure fit in combination with the respective femoral or tibial prosthesis component. At the same time, osseoconduc-tion at the bone-implant interface should be promoted. The new TrabecuLink FlexiCones meet these important requirements due to their characteristic features: they are stable, elastic and variable. On request, they are also available as a patient-specific custom-made implant with the HX coating.
TrabecuLink Femoral Cones are available in sizes XS, S, M and L and in 3 zone (left and right), 2 zone (neutral) and proximal (neutral) versions.
Stable fixation through high primary stability and good fit.
These features ensure that the uncemented FlexiCones are particularly stable:
- High primary stability and good fit
- Cementless implantation on the bone side for bone regeneration
- Inner metal wall as protection against contact with bone cement
- Secure cement fixation of the knee prosthesis due to additional, revision-friendly notches
Elasticity through bending axes for individual adaptation.
The special elasticity of the FlexiCones results from the elastic design:
- Bending axes for individual adaptation
- Spring effect for easy surgical positioning and high primary stability
- Mechanical compression to promote bone regeneration
TrabecuLink Tibial Cones are available in four sizes (XS, S, M and L) and four variants (full, right half, left half and half).
Versatile combinations: TrabecuLink Femoral and Tibial Cones are compatible with the entire LINK Endo-Model knee family.
High versatility due to possible applications with the entire LINK Endo-Model knee family.
TrabecuLink Femoral and Tibial Cones are highly versatile and can be used with the complete LINK Endo-Model knee family. The cones are available for all sizes of hinged knee prostheses.
The three-dimensional TrabecuLink structure promotes osseoconduction and microvascularization and thus functional bone ingrowth.
The three-dimensional TrabecuLink structure with its pore size, porosity and structure depth provides a very good basis for promoting osseoconduction and microvascularization. This is also the case when considering the protein layer that fills the structure of the bone precursor cells (fibronectin-vitronectin-fibrinogen).
The perfect tension at the compression point promotes osseointegration.
For example, the FlexiCones are inserted by press-fit and, due to their elasticity, they are compressed by the surgeon and pressed against the bone during insertion. This mechanism further promotes osseointegration.
