State of the Art Instruments Completely guided ream only preparation Streamlined trays for simple workflow

CONFIDENCE from over a decade of clinically proven innovation in 3D printing

Reliable FIXATION [2,3,6] Biological FEATURES [1,7,8] Proven PERFORMANCE [1-15]

About

AMF TT Cones are intended for use in skeletally mature patients with bone defects or poor bone quality (osteoporotic bone) or in case of sclerotic bone that requires supplemental metaphyseal fixation in the clinical judgment of the surgeon.

The AMF TT Cones are offered in 4 constructs: Central Femur, Bicondylar Femur, Central Tibia, and Peripheral Tibia.

The AMF TT Cones are knee prosthesis components intended to be used to:
  • reinforce the medullary cavity of the tibia and femur
  • fill a proximal tibial or distal femoral defect that may result from the removal of a primary knee system
  • provide support to the tibial baseplate or femoral component by means of bone cement.
They are used in combination with the Physica cemented tibial plate, with the Physica PS femoral component and with the Multigen Plus CCK and H Systems, which are manufactured by Enovis.
AMF TT Cones are intended for uncemented fixation to the bone and are fixed to the femoral and tibial implants using bone cement.
