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
