Surgeon Perspective


William P. Barrett, M.D.

ATTUNE Knee Surgeon Design Team - Renton, Washington
“The ATTUNE Knee System with its enhanced stability and range and motion allows patients to get up and around more quickly. In my experience, my patients are able to get back to work, get back to their activities more quickly than they would in the past.”


Ryan M. Nunley, M.D.

ATTUNE Knee System Clinical Investigator - St. Louis, Missouri
“After doing the first couple of cases, my patients seemed to get out of the hospital faster, have less pain, and a faster recovery. When they came back to their visit at about the one month period, they had better range of motion. I decided that the ATTUNE Knee was the knee that I wanted to use.”



Research Findings

One year results from two worldwide studies showed improved patient reported outcomes with the ATTUNE Knee compared to other leading knee systems.4


Knee replacement surgery is a common and successful procedure. The performance of the ATTUNE Knee is in line with other knee systems.9,10

How the ATTUNE Knee System Works

Every aspect of the ATTUNE Knee has been specially designed to work with the body for a full and natural range of motion while optimizing stability.


The ATTUNE Knee is comprised of several innovative, patented technologies to give you confidence from your very first step.


Smooth Motion and Stability: The patented ATTUNE GRADIUS Curve

Designed to help provide you smooth motion and stability as you do everyday activities like walking or going up and down stairs.


Anatomic Movement: The GLIDERIGHT Articulation

This innovation was developed to improve how your patella (knee cap) interacts with the rest of your knee to provide a smooth feeling in motion.

Important Safety Information

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.

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. 2.
