Computer aided total knee replacement gets several arthritis patients off bed
80 year old Shreenivasan, an avid yoga practitioner and a resident of Bengaluru had been suffering from arthritis for several years. He had been postponing his surgery until he reached a point where he was not able to even walk, forget about his yoga. After much discussion and analysis of the technology, he underwent computer aided total knee replacement at Sakra World Hospital, Bengaluru in the month of March 2015. Within two months he was not just able to walk but was also able to do his yoga.
Hence, the computer aided total knee replacement could be perfectly termed as the perfect example of advancement in medical sciences and its integration with technology. It could also be noted that this technology is fast growing as it entails less pain, less muscle cut, less blood loss, precise,durable and more effective in restoring knee mobility, besides alleviating pain.
“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. P, renowned computer assisted knee replacement surgeon, Senior Consultant and Head, Department of Orthopedics at Sakra World Hospital. 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.
The new technology coupled with expert surgical skills has come as a great boon for knee replacement patients who continue to suffer the pain and trauma for long years due to apprehension attached to the surgery. Meanwhile about the cost part, experts say it costs the same than what a patient spends on a conventional replacement.
