Because male and female femurs are shaped differently, this system adapts to these differences with a number of special features, including smaller sizes for women and differing shapes for each gender. This system has compatibility with minimally invasive solutions.



Modified Anterior Flange

   A thinner anterior flange is designed to help avoid overstuffing and overhang.

Comprehensive Sizing

   The Zimmer Gender Solutions PFJ includes five left/right specific trochlear components.

If most of your knee joint presents no issues but the kneecap causes pain, you may be a candidate for this procedure. Your symptoms may include pain on stairs, squatting, bending and straightening the knee, or rising from a chair.

A kneecap joint replacement is a smaller operation than a total knee and can have a much quicker recovery time. This procedure may be especially appropriate for young patients with isolated patello-femoral arthritis.

This prosthesis is used on patients with the following conditions:
  • To repair the joint from earlier surgeries such as cartilage transplantation or arthroscopy
  • Various types of arthritis or chondrocalcinosis of the joint
  • Patellar dislocation or patella fracture history
  • Patellofemoral degeneration due to dysplasia
Patients with the following conditions or issues may not be recommended to receive this joint replacement prosthesis:
  • A history of infection in the joint
  • Neuropathic arthropathy
  • Severe instability or maltracking of patella, patellofemoral and/tibiofemoral joints
  • Skeletal immaturity
  • Rheumatoid arthritis and skin ulcer or recurrent skin breakdown
Additional Treatments

For patients with bi-compartmental arthritis, the Gender Solutions ® Patello-Femoral Joint system can combine with the Zimmer ® Unicompartmental High Flex Knee. The combination of these two systems allows for precise movement and rotation.
The Gender Solutions ® system can also convert to a Zimmer Total Knee in the future, if that becomes necessary.
