    • SUCCESSFUL use1, 5, 10, 11

    The LINK Unicondylar Sled Prosthesis was first implanted in 1969. It was last modified in 1981, and ever since the successful implant design has remained unchanged:

    Naturally shaped components - Polycentric femur design permits anatomically adapted reconstruction:

    • Successful polycentric femur design10, 12
    • Bone-conserving design for future arthroplasties14

    Forgiving design - “Round-on-Flat” fixed bearing design permits excellent freedom of movement, leading to patient-specific mobility13:

    • Unrestricted kinematics3, 9, 13
    • Better results compared to other implants, even in low volume sites11, 15, 16
    • Symmetrical design allows treatment of medial and also lateral gonarthrosis 2


    Proven longevity

    • Outstanding clinical outcomes document the device’s reliability11,12
    • Extensive clinical experience12
    • Unchanged design for three decades
    • Excellent documented outcomes12

    Femoral resection

    • Maximum bone conservation and preservation of soft tissues2, 6, 14

    Femoral components
    The femoral components are available in four sizes:

    •    Small (16 x 40 mm)
    •    Medium-small (17 x 46 mm)
    •    Medium (18 x 52 mm)
    •    Large (20 x 60 mm)

    In the event of a revision, explantation is easier than with undercut stem structures.14

    Tibial plateaus
    The symmetrical shape of the tibial plateaus allows them to be used both medially and laterally. The dimensioning is adapted to the shape of the tibial head anatomy.

    All-poly design

    This version is available in four heights: 7, 9, 11 and 13 mm, and four diameters: 45, 50, 55, and 58 mm.

    • Modular, anatomically adapted prosthesis components
    • Wide choice of sizes for every stature, irrespective of gender or ethnicity5
    • Fine size increments enable natural reconstruction of the posterior offset
    • Secure fixation against shear and rotational forces6

    Versions

    Fixed Bearing as cruciate ligament-conserving (CR) or cruciate ligament replacement (PS) and Mobile Bearing (CR/CS) are available. GEMINI SL Fixed Bearing consists of a single tibial metal casing, which enables both cruciate ligament preservation (CR) and cruciate ligament replacement (PS) options. This simplifies the choice of implant and gives intraoperative flexibility.
     

    Designs

    Numerous different versions enable customization to suit different bone structures and possible sensitivity. The system permits cemented and cementless anchorage. Additional PorEx Surface Modification can reduce ion release, and can also reduce wear because the coefficient of friction is lower.14 Modular tibial components allow approximation of tibial stems, which can ensure stability when bone condition is poor.7

    In addition, a SpheroGrip version with monoblock tibial metal casing is available.

    If the ligaments and capsule are intact and joint stability is good, the Fixed Bearing Cruciate Retaining (CR) version can be used for natural joint reconstruction.

    The Fixed Bearing CR with moderate congruence reduces the bone loading by means of enhanced load distribution, and enables natural femoral rollback and femur rotation15.

    If the posterior cruciate ligament is insufficient or has been removed,
    the Fixed Bearing Posterior Stabilized (PS) version is used.

    Features of GEMINI® SL® Fixed Bearing PS:

    • Post-cam attachment comparable to the natural knee13
    • Uniformly large contact surface on the pin
    • Low surface load on the pin13
    • Reliable and secure coupling mechanism13
    • Minimal luxation risk13.
    • Enlarged contact surface during flexion with reduced contact load and minimal fracture risk and abrasion.13

    The concept of the Mobile Bearing allows significant enlargement of the contact surface, and therefore a reduction in contact loading8, 9 and permits a high articulation congruence with free rotation, thus improving the kinematics.10

    At the same time, the polished tibial base plate improves the abrasion behavior.10, 11

    Secure plateau fixation
    The unique dovetail guidance largely eliminates any risk of luxation of the plateau.

    The freedom of rotation provided by GEMINI SL Mobile Bearing helps to preserve the alignment of the patellofemoral and also femorotibial articulations during knee flexion. Self-alignment by means of rotation of the polyethylene PE articulating surfaces improves the postoperative kinematics.11

    At the same time, the polished tibial base plate improves the abrasion behavior.10, 11

    GEMINI SL Mobile Bearing offers the advantage of a highly compliant joint geometry with reduced surface and substrate stress distribution, while the Mobile Bearing articulation reduces the development of boundary surface bone loads.9
    Good mobility with an enlarged articulation surface.
    The high degree of articulation congruence stabilizes the knee, also in cases of loss of the posterior cruciate ligament.8, 9, 12

      The LINK Endo-Model has been in use for over 30 years as a rotational or hinge knee prosthesis for both primary and revision arthroplasties. The Endo-Model Rotational Knee Prosthesis gives you a multiplicity of options.
      The method for implanting the Endo-Model is simple and uncomplicated.2, 6 The prosthesis has an intracondylar and an intramedullary fixation, which provide a high degree of stability and protection against bacteria.1, 7 For patients with a hypersensitivity to metal, LINK also offers a special surface coating (LINK PorEx).13
       

      The Endo-Model has been used successfully for over 30 years now, and can boast an unparalleled clinical history with excellent clinical results.1, 2, 5, 8 Even after 15 years, the Endo-Model has a survival rate of 98.5%.9

      The Endo-Model enables speedy and uncomplicated implantation, while the design of the implant ensures good postoperative function.10, 11 Its excellent kinematics mean that the Endo-Model gives a high level of stability, especially in extension.3, 11 The implant allows flexion of the joint up to 142° and hyperextension of 2°.

       

      The Endo-Model is an implant with intrinsic stability.1, 5, 12 The various options (Endo-Model Standard, Endo-Model Modular, Endo-Model SL, Endo-Model W) offer a high degree of flexibility.

      • Versatile – for a broad range of solutions 7

      The dynamic TrabecuLink Femoral- and Tibial Cones are an attractive solution for cementless restoration of bone defects10 and to provide additional support for the prosthesis if there is bone loss in the proximal tibia. The combination of the dynamic design5,6 of the cones and the biocompatible material Tilastan– E11,12 is ideal for ensuring stable, long-lasting fixation and successful bone regeneration.

      The 3-dimensional TrabecuLink structure, with its pore size, porosity and structure depth, also provides an excellent basis for promoting osteoconduction and microvascularization, taking into account the requirements for the structure-covering protein layer (fibronectin - vitronectin - fibrinogen).1,2 TrabecuLink Cones can be used in combination with the long-established LINK Endo-Model knee family in a wide range of sizes and versions. The choice of sizes corresponds to the dimensions of the hinged
      knee prostheses.

      Stable – in metaphyseal fixation9,13

      • Reinforcement of the bone structure in cases of femoral and tibial bone defects
      • High primary stability, both for the TrabecuLink Cone itself and for the prosthesis component cemented in the cone
      • Cementless interface with the bone for bone regeneration


      Elastic – due to integral bending axes in the inner metal wall

      • Mechanical compression promotes bone regeneration5,6
      • Bending axes for adaptation to bone surfaces
      • Good fit ensured by structural elasticity, which also facilitates insertion of the TrabecuLink Femoral/ Tibial Cones
      • Spring effect for easier intraoperative positioning

       

      Versatile – for a broad range of solutions7

      • Can be combined with all the components of the LINK Endo-Model knee family
      • Sizes correspond to the sizes of the hinged knee prostheses
      • Customized models can be manufactured


      Protective – due to inner metal wall

      • Prevents penetration of bone cement into the TrabecuLink structure
      • Reliable cement fixation by means of specially positioned “notches” (revision-friendly)


      Environmentally friendly3,8

      • Resource-saving manufacturing of proven Titanium alloy

      TrabecuLink
      3-dimensional structure – for optimal bone ongrowth

      •  Pore geometry (porosity: 70%, pore size: 610-820 μm, structure depth: up to 2 mm) ensures excellent cell ongrowth 1,2,4

      Pore filling

      The sequence of images shows a pore of the TrabecuLink structure being filled with tissue under in-vitro cell culture conditions. The fibronectin laid down by human fibroblasts and continually reorganized over a period of eight days is visible as green fibers. Fibronectin is a component of the extracellular matrix that is formed at an early stage of the healing process. It forms a basis for the embedding of collagen, which is essential for mineralization of the tissue and ingrowth of bone into the structure. Apart from the accumulation of fibronectin, which increases over time, a clear contraction of the matrix towards the center of the pore can be observed. This contraction mechanism, which is attributable to the cellular forces acting in the tissue, accelerates the rate at which the pore is filled with tissue, compared to a layer-by-layer tissue growth (Reference: Joly et al., PLOSone 2013; https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0073545).
