ATTUNE® Knee System Linked to Improvements in Patient Quality of Life and Reduced Length of Hospital Stay
ATTUNE® Knee System Value Analysis Brief
The ATTUNE Knee is a total primary knee system designed with the goal of addressing the clinical needs of patients, surgeons and hospital providers around the world.
Extensive research and science has been included in the design to help improve functional outcomes for patients, performance for surgeons, and efficiency for providers.
The ATTUNE Knee is one of the largest research and development projects in the history of DePuy Synthes and combines the latest in design, kinematics, engineering and materials to deliver stability and motion .

DePuy Synthes is world renowned for its knowledge and development of successful knee replacement systems. Some of the iconic DePuy Synthes primary knees include the SIGMA® Knee System and the LCS™ Knee System.
Total knee replacement surgery can be a highly successful procedure . However, it is also a complex procedure. Surgeons are faced with varying patient anatomies and difficult intra-operative decisions each time they enter the operating room (OR).
At the same time, patients seek to return to the normal and active lifestyle they enjoyed prior to the onset of their joint disease.
Unfortunately, total knee patients are not always satisfied with their outcome and report differing levels of satisfaction following surgery. It is the goal of DePuy Synthes to design total knee systems that work with the surgeon to positively impact patient satisfaction .
To better understand what factors may lead to improved patient satisfaction, DePuy Synthes embarked on one of the largest research and development projects in its history.
DePuy Synthes' clinical heritage in knee replacement design is recognized in the industry. With this foundation in clinically proven design principles, the design team re-examined every aspect of knee implant and instrument design.
A world class surgeon team was assembled and working relationships with leading research facilities were established to study areas such as kinematics, anthropometrics, polyethylene wear, and instrument design.
The following system goals were established:
The patented ATTUNE GRADIUS Curve is designed with a gradually reducing femoral radius. This curve creates a smooth transition during knee bending and produces high stability of the knee by minimizing unnatural sliding of the femur on the tibia.Click to view animation
For the Posterior Stabilized design, the interaction between the cam and spine, the articular surface geometry, and the collateral ligaments is complex and essential to the function of the knee in deep flexion. The proprietary s-curve design of the SOFCAM Contact provides a smooth engagement for gradual femoral rollback and stability in flexion, while reducing the forces transferred to the tibial spine.3Click to view animation
Differentiated to current offerings, surgeons are able to match the femoral size to the insert size every time to achieve the highest conformity and optimized stability in early flexion.4Click to view animation
The patello-femoral interaction is one of the more challenging aspects of total knee arthroplasty.5 The GLIDERIGHT Articulation encompasses a trochlear groove designed to accommodate patient variation and soft tissue interaction, and patella components designed to optimize patella tracking while maintaining bone coverage.Click to view animation
To provide implant sizes that were reflective of the global patient population, DePuy Synthes collaborated with University College Dublin to conduct extensive anthropometric research. The ATTUNE Knee Femoral Sizing Line was created to accommodate the global patient population and avoid mediolateral overhang.Click to view animation
The INTUITION™ Instruments were developed to deliver efficiencies for all stakeholders and an intuitive surgical process.
These innovative instruments work with the advancements in the implant design to help balance the soft tissues and precisely control the implant position and fit for each patient.Click to view Precise Control Animation

Visitation Centres (VCs) are an established part of the DePuy Synthes Professional Education Pathway for Healthcare Professionals (HCPs). They provide the respective HCP with an opportunity to visit a recognized Key Opinion Leader (KOL) at their practice/centre of excellence in small groups of 2 – 4 HCPs. The objective of each VC is to enable the visiting HCP to have a better understanding of a specific technique/procedure that may have previously been introduced at a DePuy Synthes course or on-line at Do-Surgery.com

Knee replacements are very common these days and specialists often have the experience of hundreds and thousands of procedures.
Patients are usually told at their initial consultation who will be performing the operation, and again at the pre-operative assessment, but if you’re not told please ask. Your team will most probably include:
This will help to ensure you feel comfortable and well-informed going into surgery – because we know it can be scary – but it also helps reduce your risks.
You will undergo a few necessary tests relevant to your procedure, for example:
You might also be asked some general questions such as:
Your surgeon, or a member of their team, will ask you a few questions about your knee, as well as your health generally, to confirm that knee replacement surgery is right for you.
A careful review of your entire medical history will help the surgeon understand your pain and physical limitations, as well as the progression of your knee problem.
A physical exam will measure the range of motion of your knee and evaluate your muscle strength. The surgeon will observe how you walk, sit, bend, and move.
Previous knee X-rays will help your surgeon plan the surgery and evaluate the fit of your new knee prosthesis. Be prepared for new X-rays to be taken as part of your physical exam.
Other factors such as alcohol consumption, obesity and smoking can also impact your mobility and quality of life, so your surgeon will advise you to monitor these.
Consider the following in your bathroom:
Your GP, surgeon and hospital team will be able to help you with much more advice and practical support, so please ask them about post-operative care during one of your appointments.
Trying to stay as mobile and active as possible is one of the most effective ways of preparing for a knee replacement, as well as limiting the pain you feel because of your condition.
It might be tough as you approach the date of your operation, but even doing a few minutes per day can really make a difference.
Swimming and cycling are ideal, because both allow you to exercise your knee without exerting unnecessary strain on it. Because water is buoyant, swimming also relieves some of the pressure on your joints.
Please see below for some low impact stretches and movements that have been specifically developed to ease knee pain.
Recovery times obviously differ from procedure-to-procedure and person to- person, but regardless of how you feel, it’s important to try not to do anything too quickly.
However, hospital support staff will want you to be feeling good as soon as possible, so don’t be surprised if they want you to straighten your knee and try to get up on your feet again within a day or two.
Generally, after knee surgery, people leave hospital after 3 to 5 days. You will be able to move around with the help of a walking frame or crutches and will need to continue using one of these walking aids for the next 4 weeks.
Other types of movement, such as stretching and turning, will also be restricted for some time as your body recovers and regains its strength.
There will be some discomfort and swelling when you get up and start moving around again. You might be given some painkillers to relieve the pain or antibiotics to help protect you from infection.
You will continue the knee exercises you began in hospital and gradually increase the number and duration of the exercises. If you used a continuous passive motion machine in the hospital, your healthcare team may ask you to continue with it at home.
You will also be advised to gradually increase household activities such as cooking, cleaning, and doing laundry.
New exercises may be added to your regimen at this point, including:
Your GP will be able to help you with much more advice and practical support – as will your hospital team – so please ask them about post-operative care during one of your appointments.
