Zimmer® Gender Solutions™ Patello-Femoral System
Expanding the Gender Solutions continuum of care
|
The Zimmer Gender Solutions Patello-Femoral Joint System is designed to provide a partial knee replacement solution – and an earlier intervention option – for patients with unresolved patellofemoral pain. The Gender Solutions Patello-Femoral Joint System incorporates science-based design features and offers a precise surgical technique through the use of a proprietary guided milling system. The system is the first of its kind to combine gender design features, superior instrumentation and an efficient, repeatable surgical technique in a patellofemoral joint system. |

Zimmer was the first orthopaedic company to recognize that when it comes to knees, men and women are different. Our groundbreaking research demonstrated that the differences are less about size – and more about shape. The Gender Solutions Patello-Femoral Joint System addresses the unmet clinical need for patello-femoral implants that more accurately address the differences between the shapes of male and female femurs.
Key Design Features Include:
-
Implant sizing – comprehensive sizing applies Gender
Solutions female design characteristics to smaller sizes (1-4), while
the larger size implant is designed to match standard NexGen®
femoral components.
-
Modified anterior flange – a thinner anterior flange is designed to
help avoid overstuffing and overhang.
- Increased trochlear groove angle –an increased trochlear groove angle accommodates the documented difference in the Q-angle of the patellar tracks of male and female knees.
Zimmer Minimally Invasive Solutions™ Procedures
The Gender Solutions Patello-Femoral System instrumentation and implants are compatible with MIS approaches which are designed to facilitate smaller incisions, less tissue trauma and shorter hospital stays.
Use of the Gender Solutions Patello-Femoral Joint with a Zimmer High Flex Uni
The Gender Solutions patello-femoral may be cleared for use with the Zimmer high flex Unicondylar knee system. This bicompartmental solution can address presentations of both disease of the patello-femoral joint area and one of the distal (usually medial) condyles

Material Strength The Gender Solutions Patello-Femoral Joint System offers a bone-conserving implant design made of strong forged cobalt chrome. Implant strength was verified by Finite Element Analysis (FEA), under conditions of maximum load (during stair descent) |

|
Articulating Geometry The Gender Solutions Patello-Femoral Joint implant utilizes proven NexGen patellar contact geometry. Testing has been performed to establish the contact area of the NexGen patella on the Patello-Femoral Joint implant. Testing has also provided measurement of subluxation resistance of the NexGen patella on the Patello-Femoral Joint implant. |
|
|
Patella Support The Gender Solutions Patello-Femoral Joint implant provides patellar support through frequent high-load daily activities. Patella transition analysis has been performed on the Patello-Femoral Joint implant, as well as on the Patello-Femoral Joint implant combined with the Zimmer Unicompartmental Knee System. |
