Advantages of Computer Assisted Surgery (CAS)

The CAS System allows your surgeon to more accurately position your implant, which optimizes the alignment of the implant. An accurately positioned and aligned implant gives the artificial joint an optimal distribution of forces, which translates into more equal amounts of wear on the surfaces of the device. The more precise the alignment, the less wear and loosing that potentially occurs over the long-term and the longer your implant will last. With a well-aligned implant many patients find they may not have to be as concerned about a complex revision surgery later which is caused by premature implant failure due to poor alignment. 1

There are many types of CAS technologies being used by surgeons, and not all are the same. One of the major differences between these devices is whether the surgeon manually positions the cutting instruments by hand, or whether the computer electro-mechanically positions instruments (as is the case with PiGalileo™). It is believed that by eliminating the error associated with manual handling of these instruments, systems like PiGalileo™ that have mechanical instrument positioning technologies can provide an even higher degree of precision and accuracy.
