Gender Solutions® NexGen® High-Flex Knee

Product Description

The Zimmer Gender Solutions NexGen High-Flex Knee Implants compensate for the most important differences between women’s and men’s knees.

A growing body of research has led to breakthroughs in distinctive female and male diagnoses and treatments — for conditions ranging from heart disease to rheumatoid arthritis. The need to account for gender-specific solutions in orthopedics is  apparent…

  • Orthopedic surgeons have reported anatomical differences in women’s and men’s knees for years1-8
  • Orthopedic surgeons often have to consider intraoperative adjustments during knee surgery to accommodate women’s anatomical differences4
  • Women account for nearly two-thirds of knee arthroplasties performed annually in the U.S9,10
  • Women are three times more likely than men to forego knee arthroplasty11
