Joint replacement surgery is a combination of precision and surgical skills. The most important aspect of knee replacement surgery is to accurately restore the mechanical alignment of the leg. Computer navigation improves component position and alignment after knee replacement; thereby it is expected to further improve the results.
The use of such a technology has certain additional benefits. Not only does the computer guide the accurate bony cuts, but they can also be carried out with a small incision, which is called ‘minimally invasive surgery’ (MIS). Computer navigation also reduces the risk of complications by providing constant guidance and monitoring during the surgery.
However, there are few disadvantages of Computer Navigation. Technology is expensive and has long learning curve. If the bone mapping is not done accurately then there is high chances of error in the component final position.
