Gender Specific Knees

I've had some questions recently about Zimmer's gender specific knee, which is targeted at female patients. I am actually pretty upset about what is a blatant attempt to market unproven designs directly to patients. It is true that femaie knees are generally smaller and have a slightly different groove for the knee cap than men do. However, most implants already take this into account and have for years. There is no reason to label a knee "specific to women" other than to steer them to a Zimmer implant. I believe that my patients are smarter than that and will see through what is basically marketing hype. Unfortunately, we often spend a lot of time talking about non-issues like gender specifics rather than important things, like getting through the surgery in the safest and smoothest fashion possible.
