How is this different from the other options?

With a standard knee replacement, the surgeon typically uses mechanical instruments, including a long metal rod inserted inside the femoral canal. With Pixee, this rod is not needed. Instead, your surgeon wears augmented reality glasses that show real-time guidance to help position your implant precisely, based on your own anatomy. Only small pins are inserted in your bone to hold the instruments in place during surgery. The goal is better-aligned knee after surgery, which can help it feel more natural and may help it last longer.
