1 Computer Assisted Knee Replacement Surgery By (insert surgeon name)

2 Knee Replacement Surgery Arthritic surfaces on the tibia and femur are removed Bones are prepared for new covering Femoral and tibial components are attached Patella is resurfaced

3 Addressing Implant Alignment

4 Malpositioning can lead to… Early loosening Increased poly wear Poor function

5 Computer assisted surgery can assist the surgeon in providing proper implant alignment, even through small incisions

6 What is computer-assisted surgery? A new approach to knee replacement The patient’s specific anatomy is simulated and displayed on a computer during surgery Computer provides information about where to place components for proper alignment

7 CAS – Common names Computer Assisted Surgery (CAS) Image Guided Surgery (IGS) Computer Assisted Orthopaedic Surgery (CAOS) Computer Navigation

8 Types of CAS Passive vs. Active Systems –Use of wires or infrared to communicate to the computer Open vs. Closed Systems –Whether a system’s software can be used with multiple manufacturers’ implants (open) or those of one manufacturer (closed) Image vs. Imageless Systems –Use or non-use of CT scans or fluoroscopy to register patient anatomy

9 Ci ™ System DePuy Orthopaedics’ computer-assisted surgery system, powered by a leading computer-assisted surgery company Passive and image-free Hardware and software are unique to DePuy for use with clinically proven implants. Optional instrumentation, designed specifically for use with the Ci ™ System, gives surgeons fine-tune precision and reduces the traditional number of surgical steps required

10 How does the Ci System work? Patient’s anatomical information is entered into the computer through a process called registration. Computer calculates the best position to place the components for accurate alignment. Camera searches for arrays placed on the patient via infrared signals. Information is fed back to the camera and communicated to the computer

11 Why are surgeons using the Ci System? Assists with new techniques, such as smaller incisions, that reduce visualization Assists with intraoperative decision making during technically demanding procedures Enables better precision and accuracy Addresses patient demand for the latest technology

12 Benefits Guides surgeon in areas that are difficult to visualize Relays specific measurements not previously available to surgeons Gives precise, accurate data on the patient’s specific anatomy – not a “standard” patient anatomy Fine-tuning instruments allow surgeons to make adjustments within 1 mm and 1 degree of accuracy, guided by on-screen imaging
