PREMISE

Developing a new system

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 .

PROMISE

Extensive research and science combining the latest in design kinematics, engineering and materials has been incorporated in the ATTUNE Knee System to deliver a high level of STABILITY IN MOTION .

PROMISE

Innovative
Comprehensive
Integrated

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:

  • Improve function through motion and stability
  • Improve patient fit
  • Improve patello-femoral function
  • Improve design and materials for implant durability
  • Advance surgical process for implant positioning
 

FEATURES AND BENEFITS

ATTUNE GRADIUS™ Curve

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.

SOFCAM™ Contact

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.3

LOGICLOCK™ Tibial Base

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.4

FEMORAL SIZING

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.

PATIENT INFORMATION

PATIENT JOURNEY PRE-SURGERY KNEE REPLACEMENT GUIDE

Feeling comfortable in hospital

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:

  • A consultant (a senior-level surgeon who will lead the procedure)
  • A team of junior doctors (to support the consultant)
  • An anaesthetist (to manage your pain)
  • A physiotherapist (to get you as fit as possible before and after replacement surgery)

Pre-operative assessment

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:

  • Blood test
  • Skin swab
  • Heart rhythm test (ECG)

You might also be asked some general questions such as:

  • What is your general medical history?
  • Have you had any operations and/or complications?
  • Are you currently on any medications? (if yes, please bring a list with you)

Evaluation and preparation

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.

Medical history

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.

Physical exam

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.

X-ray review

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.

Lifestyle management

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.

Preparing yourself and your home

  • Arrange for friends and/or family to help you out at home after you come out of hospital
  • Arrange a lift home from hospital
  • Cook some meals in advance for the freezer
  • Make your home as tidy and organised as possible, with all of your vital bits and pieces (phone, keys, money, address book) in easy-tofind places
  • Buy items such as a long-handled sponge, a footstool and grabbing tool to make your life as easy as possible

Some tips to make your home recovery-friendly

  • Convert a ground-floor room into a temporary bedroom
  • Remove any mats or rugs that you could slip on, or that could get caught on the tip of a walking aid or a crutch, and use non-slip mats in the bath
  • Repair loose carpeting. Mark changes in the floor levels in some obvious way (e.g. bright, non-slip tape)
  • Securely fasten all electrical and phone cords around the edges of the room
  • Move furniture around to clear easy paths throughout your house
  • Make sure your stairway bannisters are secure
  • Add a couple of nightlights around the house, especially in your bedroom
  • Remove all unnecessary clutter: clear countertops; organise your daily items within arm’s reach to reduce the need to reach up or bend down;
  • install slide-out shelving and adjustable rods; invest in baskets and other storage solutions

Consider the following in your bathroom:

  • Install an elevated toilet seat
  • Add a shower seat or transfer bench
  • For safety and support, install grab bars in the shower, by the bath
  • and near the toilet
  • Replace fixed shower heads with hand-held shower heads

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.

Knee exercises to help you prepare for surgery

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.

Knee bends

  • Stand close to a wall with your knees shoulder-width apart
  • Lean against the wall, and slide your back down by slowly bending your knees
  • Let your knees point slightly outwards in line with your feet as they start to support your weight
  • Return slowly up to your starting position, feeling your hamstrings tense
  • Repeat 10 times

Leg raise

  • Sit upright in a firm chair
  • Slowly straighten and raise your left leg until your hips and leg are in line
  • with the chair seat
  • Hold for 5 seconds before slowly returning to your starting position
  • Repeat 10 times, alternating legs

Thigh stretch

  • Sit on the edge of a firm chair and hold your back straight
  • Keep your right leg bent and extend your left leg out, resting your left heel on the ground
  • Bend your whole body forwards over your left leg, keeping your hamstring tense
  • Repeat 10 times, alternating legs

Single leg squat

  • Stand with both feet pointing outwards, shoulder-width apart
  • Slowly raise your right leg off the ground and balance on your left leg
  • Now bend your left leg slowly and lower yourself 6 inches, all the while keeping your foot straight
  • Return slowly to your starting position
  • Repeat 10 times, alternating legs

Recovery and discharge

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.

Weeks 1 to 6

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.

Weeks 6 to 12

New exercises may be added to your regimen at this point, including:

  • Toe and heel raises – alternating between rising up on toes and heels while standing
  • Partial knee bends – bending your knees slowly up and down while standing
  • Leg balance – standing on one foot at a time
  • Step-ups – raising alternating feet onto a step and straightening your leg
  • Bicycle – riding a stationary bicycle

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.
