Gender Solutions® Patello-Femoral Joint

The Gender Solutions® PFJ System is designed to address the anatomical differences amongst men and women with a reproducible instrumentation platform, aiming to simplify patello-femoral arthroplasty (PFA).

Compared to total knee arthroplasty:

  • PFA is associated with shorter postoperative rehabilitation1
  • PFA is associated with better knee kinematics in the sagittal plane because of the preservation of the tibiofemoral articulation, menisci, ACL and other supporting ligaments1
  • PFA patients showed better functionality, less blood loss and greater return to activity2

The Gender Solutions PFJ System features:

  • Increased trochlear groove angle*
  • Modified, thinner anterior flange*
  • Proprietary guided milling system

The PFJ Prosthesis is compatible with Gender Solutions Natural-Knee® Flex, and NexGen® Standard All-Polyethylene, Porous, or Augmentation Patellae.
