What is the ATTUNE® Knee System?

If you’re considering knee replacement surgery, the ATTUNE® Knee System is a state-of-the-art knee replacement system that can help you on the path to a faster recovery. In a clinical study, patients required significantly less time to meet the necessary criteria to leave the hospital3, and gained significantly greater range of motion, when compared to another leading knee replacement system, both two and six weeks after surgery.2

Is the ATTUNE® Knee Right for Me?

The knee is a complicated set of tendons, muscles, ligaments and bones. So to produce a knee replacement system that gives you more stability and a natural range of motion, we’ve developed innovative, patented technologies combining the latest in design, kinematics (the study of movement), engineering and materials. Go to the “Why The ATTUNE Knee” page to learn more about why it could be right for you.

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.
