:: Perfection

Surgeon uses his eyes and fell to achive accuracy. Computer Image Guided Surgery enhances these modalities for higer accuracy.

Imagine the world of Cricket without the third umpire to judge the run outs. In the past the umpires did not get all the run outs precisely – failing to judge it correctly about 20% of time in close calls. Unfortunately there was no option of TV replays in those days and everyone accepted the ‘fallacies’ of the human eye and accepted the system. There was resistance to change but now the TV replays and the third umpire judging run outs is well accepted – simply because they are accurate and reliable.

Same is with knee replacement surgery. Good surgeons get near accurate alignment most of the times. A detailed survey reveals accuracy level of experienced surgeons up to 75%. An experienced surgeon’s eyes are good enough to judge up to 5 degrees out of alignments. There are mechanical instruments which help to refine this error but these systems still have limitations and fail to produce accurate alignment in about 25% of cases. Knee replacements which are out of alignment by more than 3 degrees have higher chances of early failure.

Obviously a system was necessary to improve on this state to achieve perfection. The combination of an experienced surgeon and highly accurate Knee replacements which are out of alignment by more than 3 degrees have higher chances of
early failure. This is where the Computer Image Guided Surgery comes into picture. Image Guided Surgery achieves correct alignment nearly every time.
