Knee replacement technology has undergone sea change with years passing by. With time and progress in technology the surgeons and researchers are constantly working towards achieving perfection in each surgery. One such example is ‘Computer Navigated Knee Replacement Surgery.
Pin less Computer Navigated Total Knee Replacement technology is used by Dr Anil Arora, the head of unit and lead consultant of department of Orthopedics at Max Super Specialty Hospital, for Knee Replacement, in North India.
Computer navigated system for knee replacement uses special sterile probes which are touched to various parts of your knee during surgery to create a 3D Model of your knee in the computer with the help of infrared camera.
With the guidance of Computer navigated system for knee replacement, knee is then replaced, and the position of implant confirmed, to be almost hundred percent sure of positioning and balancing.
Pin Computer navigation technology came into practice about a decade back. But it never became popular because of serious drawbacks. Earlier versions of computer assisted replacements used drilling extra few pins in thigh and leg bones to attach Arrays (Guides).
Drilling extra holes in thigh and leg bones can sometimes lead to complications. So the advantages of earlier version of computer navigation were attended with chances of some extra complications also.
The latest state of the art Pinless Navigation does not require drilling extra holes in thigh and leg bones. It is recommended rather than using earlier versions of pins.
Computer assisted surgery helps surgeons align the patient’s bones and joint implants with a degree of accuracy not possible with the naked eye. Everyone is different and so are their knees! Computer navigated surgery takes into account each patient’s shape and size of the knees and allows a surgeon to use, what is essentially a mini GPS system, to register the exact bio-mechanic anatomy of the leg and knee joint to ensure each replacement is as accurate as possible.
