Computer Assisted Surgery (CAS) 

This approach can reduce surgical errors and improve surgical outcomes associated with knee and hip surgery. Computer assisted orthopedic surgery includes techniques that enhance the identification of the surgical anatomy, thereby improving surgical accuracy. 

These computer based tools are invaluable. They increase the repeatability and accuracy of surgical procedures and help improve quality control in orthopedic surgery. 

CAS is an excellent surgical method for total knee replacement surgery. Also referred to as computer navigation, the procedure uses an operating room-based computer and infra-red transducers pinned to the thigh and shin bones. The patient’s unique anatomy is mapped and displayed on the computer screen. The surgeon uses this real time anatomic data to plan and verify bone cuts for precise implant placement. 

Computer assisted surgery can be used with traditional total knee replacement or minimally invasive (MIS) total knee replacement. CAS has enhanced value when combined with MIS technique. This cutting edge technique requires unique surgical instruments and special surgeon training. CAS ensures proper positioning of the knee implants using smaller incisions and muscle sparing techniques, often times resulting in a shorter hospitalization, faster return to work and recreational activities and a less painful recovery process for the patient. 

Advantages of Computer Assisted Surgery 

• Enables the surgeon to create accurate and reproducible bone cuts helping to ensure accurate placement of Total Knee implants. 
• Greatly reduces possibility of MIS technique component mal-positioning. 
• Vital for complex TKR when unusual bone deformities are present. 
• Valuable tool when performing revision total knee replacement.
