Description

The system was developed with the aim to create an exact duplicate of the individual patient's natural joint movements and the stability of the joint. The femoral component is wide enough to cap the resurfaced condyles, be of a size that reproduces the AP dimension of the femoral condyles, and adequately distributes the weight bearing forces and resists subsidence. The tibial component is more than 6 mm in thickness to resist wear. The femoral component in situ together with the tibial component can adequately restore the normal joint line and correct the alignment towards, but not beyond the neutrai mechanical axis. The joint line level can be restored, and therefore distal femoral resection should equal the thickness of the femoral component. These features are all obtainable with the Biotech BMI unicompartmental knee system, and are in full accordance with the rational for this type of knee arthroplasty. Lasting Fixation: The Biotech BMI unicompartmental knee system is manufacturée! from cobaltchromium, with optional titanium and polyethylen for the tibial parts. The spécial surface treatment of both femoral and tibial components creates a strong bond between cernent and implant. The spécial pegs for both the fémoral and tibial components increase the surface of fixation, and grossly enhance rotational stability of the implant. Single set of Instruments: The instrument ensures precise bony preparation of both femoral and tibial side, with accurate détermination of the lower extremity axis.
