METS Modular Implants

METS Proximal Tibia Implants

The METS proximal tibia replacement system is designed as a modular system that can be used to replace diseased or deficient bone in the proximal tibia.

proximal tibia implant photoThe system consists of:

  • A SMILES Knee
  • A range of shafts in 15mm increments to suit differing lengths of resections
  • A range of hydroxyapatite coated and uncoated collars of different diameters to match the size of the re-sected bone
  • A range of cemented stems to provide secure fixation in the intramedullary canal

Individual components of the tibial shaft are connected using inter-locking taper junctions allowing quick and easy assembly.

The METS proximal tibia is supplied with the SMILES knee with options of a rotating hinge and a fixed hinge. Both are suitable for primary and revision cases, and for cases where there is significant erosion of the proximal tibia. The fixed hinge is supplied for cases with significant loss of soft tissue function where additional constraint is required. For exceptional cases the METS modular system can be used in conjunction with custom made components.

The minimum resection required for the METS proximal tibia is 60mm and the maximum is 225mm.

Custom proximal tibia prostheses

For cases that cannot be accommodated by the METS proximal tibia modular system we routinely produce case specific custom prostheses. Solutions can include the addition of a wrap around stem feature to assist in preserving the soft tissue attachment to the residual bone section.


  • Periprosthetic fracture
  • Trauma to proximal tibia
  • Gross bone loss or poor bone quality in proximal tibia
