Computer aided knee replacement(also known as computer assisted knee replacement surgery or computer aided knee arthroplasty) is attracting a large number of medical tourist to hospitals in India. The less invasive nature of this medical procedure, will also help increase the popularity in India of the total & partial knee replacement surgeries. In this procedure a computer is installed with a medical surgery software and is connected to a surgery infra red camera & specialized surgical instruments. This “knee surgery computer system” is used by the surgeon to perform the knee replacement. This allows for more precision & accuracy during the surgery.The surgeon can see the computer generated image real time while preforming the knee operation. The alignment of the knee replacement implant is more accurate (accuracy of 0.5 mm and 0.5 degrees) & predictable compared to how it would be when doing surgery just with naked eyes. The system acts as a GPS for the human body helping the surgeon by providing real time navigation information and enhanced 3-D visualization. The International Society for Computer Assisted Orthopaedic Surgery is a non profit organization working towards the growth of this field. Other advantages of computer aided knee replacement surgery are: – Smaller incisions as its a minimally invasive surgery – Faster recovery – Less bleeding and lesser chance of blood clotting. – Less pain – Easy on patient & doctor – Reduces chances of human error – Increased implant longevity as it reduces chances of bad alignment requiring revision surgeries. The total knee replacement usually lasts about 10 to 15 years. With the computer assisted orthopedic surgery the knee replacement can last up to 30 years without needing an replacement. These advantages are achieved as computer assisted total knee replacement is a minimally invasive surgery (also known as laparoscopic or endoscopic surgery). In these type of surgeries specialized instruments, monitors, fiber optic lights, miniature cameras and computer monitors are used to perform the surgery though a small incision unlike a traditional surgery which is more invasive. Although the surgery is performed using a computer system, this does not reduce the knowledge & experience that the surgeon needs for a successful knee replacement. The procedure combines the surgeons skill with computer technology. In India many surgeons have this expertise and experience. Research has shows that not only does the computer aided knee replacement results are clearly more favorable in comparison to conventional knee replacement surgery, but also it significantly reduces the chances of error outliers. With advancements in surgical robotics & the field of computer assisted surgical navigation, the use of traditional surgery means for knee replacement will reduce. Computer assisted knee replacement is the future of knee replacement surgery. A number of people visit India for this cutting edge medical procedure. Although premier hospitals in USA, Canada & UK have this latest medical procedure available, majority of the hospital don’t. The associated price & cost of the Knee replacement surgery in India, Costa Rica & Mexico is about 50-80 percent less that what is in the USA. Medical Tourism Corporation facilitates computer assisted(aided) knee surgery in India. The typical price of this surgery in India is about 20 percent of what is would cost in the USA. This price includes the estimated travel & lodging expenses that would be occurred for a person to fly form North America to India.
