Distinct Difference - More Natural Movement
The angle between the pelvis and the knee, called the quadriceps angle (Q angle), affects how the kneecap tracks over the end of the thighbone as the knee moves through a range of motion. Women tend to have a differenct angle than men due to their specific shape and contour. The traditional artifical knee tends to track at an angle that may lead to a woman's knee feeling "unnatural" as it moves. The Zimmer Gender Solutions Knee was designed to accommodate the tracking angle of women's knees and function more like a natural knee.
Patellar maltracking remains a concern - particularly with females - following total knee arthroplasty.¹ Based on research, Zimmer designed the Gender Solutions Knee to replicate the distinct Q-angle of women.
