Modular system for limb preservation

The KAM-TITAN knee arthrodesis system is used when a knee endoprosthesis is no longer an option, e.g. after failed septic knee endoprosthetics or multiple failed revisions or following post-traumatic involving loss or damage to the extensor mechanism.

The design is based on the diaphyseal fixation philosophy of the proven MRP-TITAN system, which has been used successfully in clinical practice since 1993.

In addition to the neutral module of the KAM-TITAN, anatomic left and right variants are available. The leg axis can therefore be set to 0° or 6° valgus. Even in cases of extremely poor initial bone quality and where there is no prospect of bone union, a secure connection between the upper and lower leg can be achieved using the prosthetic stems and arthrodesis modules.
The cross-section of the cementless prosthesis stems is conical with star-shaped ribs. The surface is textured to promote cementless bone ingrowth.

The ribs are arranged symmetrically in the longitudinal direction and provide protection against rotation, whilst the conical stem geometry reliably counteracts both rotation and subsidence.

Clinically proven

Medium- and long-term clinical results (4,7,8) as well as clinical experience (1,2,3,5,6,9) document the effective treatment provided by the KAM-TITAN knee arthrodesis system.

Material

  • Proven biocompatible titanium alloy Ti6Al4V
  • Titanium nitride (TiN) coating on the screws

Design & Function

  • Proven cementless bone-side anchoring through the use of MRP-TITAN prosthetic stems
  • Conical, star-shaped cross-section and continuous longitudinal rib design of the cementless prosthetic stems
  • Alternative cemented stem variants
  • Continuously adjustable external rotation of the lower leg
  • Established, reproducible connection and securing of the conical plug-in joint between the prosthesis stem and arthrodesis module
  • Secure coupling of the tibial and femoral arthrodesis components
  • Variable varus angle: neutral 0° or 6° left/right at 7° flexion
  • Tibial and femoral arthrodesis modules coupled in flexion from 35°

______________________

Sizes & Variants

  • Universal neutral tibial arthrodesis module
  • Femoral arthrodesis modules for 0° or 6° varus (left/right) with 7° flexion
  • Cementless prosthetic stems, straight, lengths 140 mm and 200 mm (Ø 13–30 mm)
  • Cementless curved prosthetic stems, lengths 200 mm (Ø 13–30 mm), 260 mm and 320 mm (Ø 11–29 mm)
  • 1 mm incremental diameters of the cementless prosthetic stems
  • Straight cemented prosthetic stems, lengths 140 and 200 mm (Ø 12 mm)

Advantages

  • Consistent avoidance of CMR substances (carcinogenic, mutagenic, toxic to reproduction) that require labelling → No risk of metal intolerance to cobalt-chromium material
  • Fine-tuned adjustment of leg length and continuous adjustment of lower leg external rotation
  • Construction using trial implants in situ
  • Withdrawal options available at any time
  • Simple instrumentation technique
  • Immediate weight-bearing capacity due to high primary stability
  • Early mobility
  • Clinically proven (1–9)
