What is the LEGION Knee with OXINIUM Technology?
The LEGION Total Knee System has been used for over 20 years2 in more than a million knee replacements. It’s available with OXINIUM Technology, our award-winning1 implant material made of oxidized zirconium.
The material in your implant can affect its performance. That’s why we offer implants with OXINIUM Technology. We engineered the material for strength and durability, and to provide patients with a long-lasting implant.2-8
What are the benefits of the LEGION Knee with OXINIUM Technology?
Implants made with OXINIUM Technology have shown benefits over those made with cobalt chrome, another common material. Compared to cobalt chrome implants, OXINIUM implants offer:3,4,6

What are the risks involved?
All surgery has risks and the potential for complications. Talk to your surgeon about any concerns you may have before you decide on treatment. Some of the possible risks and complications for knee replacement include:
Blood clotting
Blood clotting problems – such as deep vein thrombosis (DVT) or pulmonary embolism (PE) – may occur after surgery and interrupt normal blood flow. Your medical team may recommend medications and exercises to reduce the risk.Infection
Infection may occur at the surgical site or elsewhere in the body. If a serious infection occurs, additional surgery or removal of the implant may be needed.Pneumonia
After surgery, pneumonia or other breathing problems may develop. Your medical team may recommend measures to reduce the risk.Nerve problems
Nerves or blood vessels in the knee area may be damaged during surgery.Long-term pain and stiffness in the knee
Most patients experience pain relief after knee replacement, but some may continue to have pain. Similarly, some patients may develop joint stiffness. Following the recovery guidelines provided by your medical team may help reduce this risk.Implant wear or failure
The knee implant may become worn, loose, or damaged. It may not perform as expected. In some cases, another surgery may be needed to correct or replace the implant.
This is not a complete list of risks. In some cases, you may need additional surgery to address a complication. Talk to your surgeon about the possible risks for your specific health situation.

Not everyone is a candidate for the LEGION Total Knee System with OXINIUM Technology, and individual results of joint replacement will vary. Implants are intended to relieve knee pain and improve function but may not produce the same feel or function as your original knee. Every patient's case is unique and each patient should follow his or her doctor's specific instructions. Potential risks include loosening, wear, and infection that may result in the need for additional surgery. Discuss your implant options with your surgeon. Please discuss nutrition, medication, and treatment options with your doctor to make sure you are getting the proper care for your particular situation.
