Patellofemoral Replacement of the knee
If you have arthritis that is localized to the patellofemoral compartment (behind your knee cap), you might have pain limited to the front of your knee. Typically patients with patellofemoral arthritis experience increased pain going up and down stairs, arising from a seated position, or getting out of a car, and have very little pain walking on level ground.
When non-surgical interventions no longer relieve your pain, you may be a candidate for a patellofemoral replacement. Through a minimally invasive approach, the back surface of the arthritic kneecap is replaced with a very smooth plastic button and the front of the femur is replaced with a highly polished chrome cap.
