Broadcast:
Greater Range of Motion While Sparing Healthy Bone Tissue
In a live Internet webcast on December 6, 2007, Lawrence S. Crossett, M.D., will perform two knee replacement surgeries using the LCS® Complete™ Mobile Bearing Knee Systems from DePuy Orthopaedics, Inc. This broadcast will take place at the University of Pittsburgh Medical Center (UPMC) Shady Side Hospital in Pittsburgh, Pennsylvania. DePuy is making the broadcast available for free via www.OR-Live.com.
At 6 P.M. EST Dr. Crossett will perform a primary knee replacement surgery that will highlight the LCS® Complete RPS, a mobile-bearing knee implant that is designed to provide increased range of motion while sparing the patient's natural, healthy bone tissue.
Earlier in the day at 3 P.M. EST Dr. Crossett will perform a revision knee replacement surgery using a new revision implant, the LCS® Complete™ System. This system helps diffuse loosening forces from the increased mechanical constraint and offers surgeons increased fixation through the use of metaphyseal sleeves on the femoral and tibial side.
About Knee Replacement
The demand for knee replacement is growing rapidly. It is estimated that the number of primary total knee replacements will increase by 673 percent -- to 3.48 million -- in 2030. This is due in part to the growing number of Baby Boomers with osteoarthritis and the rise in obesity among the population.1
As with any medical treatment, individual results may vary. Only an orthopaedic surgeon can determine whether an orthopaedic implant is an appropriate course of treatment. There are potential risks, and recovery takes time. The performance of the new joint depends on weight, activity level, age and other factors.
About the OR-Live Broadcast
Surgeons, patients, caregivers and others may view this procedure for free on the Web at www.OR-Live.com. Information is available at this site about how to view the broadcast. The 6 PM EST surgery broadcast will be moderated by Brian D. Haas, MD, Clinical Director, Rocky Mountain Musculoskeletal Research Laboratory, Denver, Colorado and Clinical Director, Colorado Joint Replacement, Denver, Colorado.
The 3 PM EST surgery broadcast will be moderated by James E. Dowd, MD, Assistant Professor of Orthopaedic Surgery, Eastern Virginia Medical School, and Director of Clinical Research, Jordan-Young Institute, Virginia Beach, VA.

Additional Information about Primary Knee Replacement
DePuy Orthopaedics, Inc., one of the world's leading orthopaedic companies, offers both a rich history of innovation in knee replacement and a long history of clinical success in knee replacement, including:
The only FDA-approved Rotating Platform knee in the US, helps to accommodate normal movement
High-flex Rotating Platform knee replacements that allow for deep knee bending and reduced implant wear
The Rotating Platform Knee is based on a revolutionary technology, the mobile bearing knee, which DePuy Orthopaedics pioneered 30 years ago. Today, nearly 1,000,000 mobile bearing knees have been chosen by surgeons and patients around the world. The Rotating Platform Knee is the only FDA-approved mobile bearing knee implant available in the United States.
Advanced technologies are revolutionizing knee replacements. Among the good news in recent years for people with osteoarthritis is the Rotating Platform knee implant. This knee replacement implant brings technological advancement to a proven design in knee implants. The Rotating Platform knee (also called a mobile bearing knee) is the only one in the United States designed to bend and rotate, helping to accommodate more normal movement.
DePuy Orthopaedics Inc. has the only FDA-approved Rotating Platform knee available in the United States. DePuy designed the first Rotating Platform knee system nearly 30 years ago.
Comparing Rotating Platform Knees to Fixed-Bearing Knee Implants
A fixed bearing knee uses a femoral component, tibial bearing insert and tibial tray. The femoral component articulates or moves on top of the insert to allow for natural motion about the knee. The insert is fixed or locked into the tibial tray. Therefore, all movement of the knee takes place on the top or primary bearing surface between the femoral component and insert.
The main difference between a fixed and rotating platform-bearing knee is in the attachment of the tibial bearing insert to the tibial tray. As mentioned, the insert of a fixed knee is locked into the tibial tray. No movement is intended at this interface. The rotating platform-bearing knee uses an insert that is free to rotate about a central post. Therefore, the rotating platform implant allows motion at the primary articulating interface between the femoral component and tibial insert as well as unidirectional motion around the post between the insert and tibial tray.
