Removing
The Guesswork
Without Removing Quality Bone.
With the increased prevalence of unicompartmental knee arthroscopy (UKA), a
system which provides a conservative approach in terms of both instrumentation
and implant design, is critically important. To address this, the ADVANCEŽ
Unicompartmental Knee System was designed with bone conserving femoral and
tibial components that provide reproducible results within a minimal incision.
Wright Medical has accomplished this with the following 3 system design requirements:
- Conservation
The resurfacing femoral implant conserves 20% more quality bone stock
compared to contemporary full resection femoral implants.1 An all-poly
tibial base design conserves bone while providing proven outcomes based on cortical bone support in place of inlay
techniques.2
- Congruency
Increased medial-lateral tibiofemoral congruency modernizes the ADVANCEŽ
Uni Knee contact area to total knee implant standards.3,4 Semi-Congruent
anterior/posterior tibiofemoral interface provides superior contact area
while allowing for freedom in implant placement.
- Consistency
Consistent alignment and reproducible clinical results are obtained through
an instrumented minimal incision technique. Increased tibial implant
fixation and more consistent clinical outcomes are provided with a dual peg
tibial base design. 5
