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 ADVANCE®
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 ADVANCE®
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
