    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

    "Round-on-Flat" Design. This design allows excellent freedom of movement, leading to patent specific mobility.13:

    • Unrestricted kinematics3, 9, 13
    • 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

    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.

     

    Metal-backed design

    This version is available in four heights: 8, 9, 11, and 13 mm and three diameters: 45, 50, and 55 mm.

    LINK PorEx Surface Modification
     

    • Significant reduction of plastic wear and release of metal ions1
    • Ceramic-like abrasion behavior1
    • Outstanding hardness1

    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.
