Home Design Performance Material High-flex The GENESIS* II system uses a hi-flex plastic component on the shinbone side of your knee. This implant's design allows you the potential to regain your original joint's natural range of motion and achieve deep knee bending with confidence. Other female knees achieve deep knee bends by cutting away more healthy bone as much as 13% more than the GENESIS II knee, in fact. The other half Most female knee implants on the market address the gender-specific design of only the thighbone side of your knee joint. Because they ignore the fact that your left and right shinbones (tibias) are shaped differently from each other (like your left and right feet), a full 20% of cut bone on your tibia could be exposed. The GENESIS II knee addresses this design issue by using anatomically accurate left and right shinbone implants for a more true fit for women. Results Orthopaedic surgeons are scientists at heart, and they want scientific evidence that an implant will be both safe and effective in their patients for a long period of time. The GENESIS II knee has been in clinical use for ten years and in that time has transformed the lives of hundreds of thousands of women.
