General Osteoarthritis Remove this slide
What’s the Leading Cause of Knee Pain?
What is Osteoarthritis?
Cartilage deteriorates and friction is created between bone surfaces.
Chronic knee pain
Difficulty with everyday activities (walking, driving, stair climbing)
Check Your Mobility If you have difficulty performing any of the movements below, it may be time to talk to your doctor about next steps

General Facts About Knee Replacement Remove this slide
Knee Replacement Knee replacement surgery is the replacement of the worn and arthritic surfaces of the knee joint
Script to Use During Animation
This animation shows that very little bone is actually removed.
The damaged cartilage, along with a very small amount of bone, is removed, and the knee replacement, which is made of metal and plastic, is then fitted to the bone to provide an artificial surface.
The components of a knee replacement comprise the femoral component, the tibial tray, and the tibial component

Are You Ready for Knee Replacement?
Does your knee hurt one or more days per week?
Does the pain interfere with your sleep?
Is it painful for you to walk more than a block?
Are pain medications no longer working?
Is knee pain limiting your participation in activities?
Has inactivity from knee pain caused you to gain weight?
Can you limit activities for a few months to recover from surgery?
Are you willing to commit to work hard during rehabilitation for a successful recovery?
Knee Replacement Facts
Based on a National Institute of Health (NIH) study, 85% of patients are satisfied with the results of their knee replacement surgery 1
1: NIH Consensus Development Conference on Total Knee Replacement, NIH Consensus Development Program ( http://www.guideline.gov/summary/summary.aspx?view_id=1&doc_id=5299 )
But You Should Also Know…
Performance of joint replacements depends on age, weight, activity level and other factors.
There are potential risks and recovery takes time.
People with current infections or conditions limiting rehabilitation should not have this surgery.
Potential complications which could result in pain, stiffness or dislocation of the joint include:
Wearing of the components
Knee Replacement Options: Rotating Platform Knees Remove this slide
Knee Replacement Options
Unique: mobile-bearing (also called Rotating Platform)
Unique Options in Knee Replacement
Rotating Platform Knee
Designed to rotate as it bends, imitating natural knee movement
The surfaces roll and glide against each other as the knee bends, just as your natural knee does
Designed for patients who want to remain active since it minimizes implant wear, compared to fixed-bearing knees 1
A multi-center internal study shows 97% patient satisfaction at 5 years 2
1: McNulty, D. et al. “In Vitro Wear Rates of Fixed-bearing and Rotating Platform Knees (Rev. 2)” (2003) 2: DePuy Multi-Center Study (2006)
Why is Rotation Important?
Script to Use During Animation
What makes the Rotating Platform knee unique is that the part of the implant that replaces the worn cartilage actually rotates slightly as you move, imitating the natural movement of the knee.
On traditional knee replacements, this piece stays locked in place. While these types of knee replacements are extremely successful, for more active patients, the rotation is beneficial because it helps minimize wear and tear on the implant.
Comment during animation:
Note the white component is moving slightly side to side
Your knee rotates slightly during normal movement:
Walking-5 degrees of rotation
Climbing stairs-8 degrees of rotation
Kneeling-15 degrees of rotation

Consequences of Delaying Surgery Remove this slide
Should You Delay Surgery? 1: Fortin, Paul R., et al. “Outcomes of Total Hip and Knee Replacement.” Arthritis & Rheumatism 42 (1999): 1722-1728 2: Fortin, Paul R., et al. “Timing of Total Joint Replacement Affects Clinical Outcomes Among Patients with Osteoarthritis of the Hip or Knee.” Arthritis & Rheumatism 46 (12) (2002): 3327-3330 3: www.jointreplacement.com
Early diagnosis and treatment for total knee replacement are important 1
Delaying surgery can lower quality of life before the operation and up to two years after surgery 2
Pre-existing medical conditions may become more serious, delaying elective surgery 3
Osteoarthritis is degenerative – it won’t get better and will likely get worse!
What to Expect With or Without Knee Replacement Severe pain Inability to walk any distance Medications don’t help Interrupted sleep Surgery is recommended 3-6 months+ Return to activities 3-6 months+ Continued or increased pain and reduced mobility 1-2 months Rehabilitation 1-2 months Continue to address symptoms Have Surgery Delay Surgery

Computer Assisted Surgery Remove this slide
Computer Assisted Surgery
What is computer assisted surgery (CAS)?
A new approach to knee replacement
The patient’s anatomy is simulated and displayed on a computer
Computer provides information about where to place the components
How Does CAS Work? Your anatomical information is entered into the computer through a process called registration This information is fed back to the camera and communicated to the computer Computer calculates the best position to place the components for accurate alignment Camera searches for arrays placed on the patient via infrared signals
Potential Benefits of CAS
Guides surgeon in areas that are difficult to visualize
Relays specific measurements not previously available to surgeons
Gives precise, accurate data on your specific anatomy
Allows surgeons to make informed decisions about precise implant placement based on detailed data from the computer
Why Use Computer Assisted Knee Replacement Surgery?
Allows surgeons to be more precise when making decisions about placing knee components
Provides the surgeon with extensive information to assist with surgical decisions
Women’s Issues in Knee Replacement Remove this slide
Important Considerations for Women
Osteoarthritis affects three times more women than men 1
Women are more likely than men to be disabled
The pain is more severe for women 2
Women’s knees rotate more than men’s, especially during deep bending (kneeling) 3
Current knee replacements are designed to fit the anatomies of both women and men
1: Hawker, Gillian A., et al. "Differences Between Men and Women in the Rate of Use of Hip and Knee Arthroplasty." The New England Journal of Medicine 342 (2000): 1016-1022 2: Harris Interactive research survey, April 2005 3: Hsu, Wei-Hsiu, et al. “Difference in Torsional Joint Stiffness of the Knee Between Genders.” The American Journal of Sports Medicine Vol. 34, No. 5 (2006): 765-770.
There is no clinical support of the need for gender-specific implants
It is too new for any clinical data; won’t know results of the implant for 10-15 years
All orthopaedic manufacturers have knee implant systems with sizes appropriate for both females and males
More than 60% of knee replacements have been implanted in women 1
Current knee replacement patients have a 90 to 95% satisfaction rate with the results of their surgery 2
1: American Academy of Orthopaedic Surgeons ( http://www. aaos .org/ wordhtml /research/stats/ Hipkneefacts . htm ) (2006) 2: The Arthritis Foundation ( http://www.arthritis.org/research/Bulletin/vol51no11/Printable. htm ) (2006)
Gender Issues in Knee Replacement: The Bottom Line
Rotation is important, especially for women
Women’s knees rotate more than men’s
In deep flexion (deep knee bending)
Only one knee, the Rotating Platform knee, is designed to accommodate your knee’s anatomical need for rotation
Minimally Invasive Surgery Remove this slide
Minimally Invasive Knee Replacement Surgery
Minimally invasive surgery (MIS) is still very new
Visibility of your knee during surgery to help ensure proper alignment is more important to the long-term success of your knee replacement than the length of your incision or even your recovery
How long your knee replacement lasts
Benefits of MIS
Some early studies of MIS have shown some benefits of the surgery (when compared to traditional, “open” surgery), such as:
Less blood loss
Shorter hospital stays
Complications of MIS
Other studies, however, have shown several complications with the surgery, (when compared to traditional, “open” surgery), including:
Increased number of surgical complications
Poor implant positioning
No difference in the length of recovery
What Really Matters When It Comes to MIS
MIS is still relatively new
It won’t be known for 10 to 15 years if the new techniques affect the long-term function and durability of the implant
You should discuss with your surgeon whether MIS is an appropriate surgical course of treatment for you
