How the ATTUNE® Knee Works

How the ATTUNE® Knee Works

The ATTUNE® Knee System is the result of a collaboration between scientists, universities, engineers and surgeon opinion leaders from all over the world, all working together to produce a knee replacement system that gives you advanced stability and freedom of movement.

What makes up the ATTUNE® Knee?

Your knee pain shouldn’t keep you on the sidelines. Every aspect of the ATTUNE® Knee has been designed to work with your body to give you a full and natural range of motion while optimizing stability, so you can confidently get back in the action sooner.1,2

Patented ATTUNE GRADIUS™ Curve

The Patented ATTUNE GRADIUS™ Curve

This is designed to help provide you smooth motion and stability as you do everyday activities.

GLIDERIGHT™ Articulation

The GLIDERIGHT™ Articulation

This is designed to optimize how your patella (kneecap) works with the rest of your knee, so your movements are as smooth as possible.

AOX™ Antioxidant Polyethylene

AOX™ Antioxidant Polyethylene

This advanced plastic material acts as a spacer between the tibia (shin bone) and femur (thigh bone) to replace the cartilage. It’s shown to have excellent mechanical strength and resistance to wear, so it can take on activities of daily living.3

In an IRB approved early outcomes study, physiotherapists collected data on 40 patients implanted with ATTUNE® Knees and 40 patients with SIGMA® CR150 knees. The results demonstrated that patients implanted with the ATTUNE Knee had statistically significant improvements in some early outcomes, other outcomes demonstrated a trend favoring the ATTUNE Knee, and some outcomes were equivalent.

As with any medical treatment, individual results may vary. The performance of knee replacements depends on your age, weight, activity level, and other factors. There are potential risks, and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can determine if knee replacement is right for you.
