Ludhiana, April 9
Dr Avtar Singh, an Amritsar-based orthopaedics surgeon, said that the advent of computer-assisted joint replacement technology had brought about a revolution in the joint replacement surgery. The most common cause of failure of joint with manual procedure was mal-alignment, which was prevalent among 30 to 40 per cent of the patients. With the introduction of the navigation system, the problem of faulty alignment of the joint had been completely eliminated and joint replacement made cent per cent accurate.
Dr Avtar Singh was delivering a lecture to orthopaedics surgeons and other members of medical fraternity, including members of the IMA, on “Latest advances in joint replacement” at the Ludhiana Club here last evening.
He remarked that the joint replaced with the computer-assisted navigation system had remarkably prolonged the life of the replaced joint vis-a-vis the manual procedure. Whereas the joint replaced with a manual procedure had a lifespan of around 10 to 12 years, the computer-assisted procedure had an expected life of between 20 to 30 years. "With improvement in the design of the implant, a patient can now comfortably fold the legs fully and sit cross-legged," he added.
Dr Avtar Singh further said that the latest techniques in joint replacement helped the surgeons to accurately and precisely align the artificial joint in the bone, which increased the longevity of the joint. Previously, after knee or hip joint replacement surgery, patients remained hospitalised for 10 to 15 days, while under this improved computer-assisted surgery, a patient can walk to his home within five days.
"A new technique of hip replacement, called surface replacement, has been developed for young patients. After this operation, the patient can sit cross-legged on the
ground. The navigation system has been found to be very useful in revision arthroplasty patients, who, having undergone joint replacement earlier, face failure of the joint due to some reason."
Dr Avtar Singh maintained that “orthopilot navigation” (computer-assisted surgery) could help in the replacement of these joints accurately, leading to prolonged life of the artificial joint. The procedure (orthopilot navigation) had brought a new ray of hope for badly deformed joints, which now could be replaced very accurately without any complications, he stated.
