“There is very little bleeding during the computer guided knee-replacement surgery. The recovery period post surgery for both knee replacement is between 2-3 weeks. Because all measuring is computer aided there is little scope for mismatch between the original and the artificial knee or any major deviation in alignment. All these ensures that there is little post-operative complication, shorter stay at hospital and the patient gets along well with the new knee for nearly 20 years,” says Dr Chandrashekar.

Dr Chandrashekar has conducted over 200 computer assited knee replacements in the past six months.

About the working of the system, Dr Chandrashekar says, the camera and the tracker is connected by the infra-red rays and the observation is displayed in the attached computer screen. As against the normal non-computer guided total knee replacement, where a surgeon has to rely on his calculations and skills to ensure the right fit, computer navigation technology guides a surgeon through the entire process of implantation of a total knee replacement. “The computerised system precisely advises surgeon on a screen as to the exact location where the new knee implants to be positioned through infrared sensing of patient’s anatomy. The technology promises to improve the short and long-term performance of the knee replacement,” says Dr Chandrashekar.
