HYDERABAD: Sunshine Hospitals has announced that a team of doctors headed by Dr A.V. Guruva Reddy, MD of the hospital, and Dr. Mark A. Synder, a designer surgeon from the US, conducted an oxinium ceramic knee surgery for the first time in the State.
“Oxinium is the name of a brand. It is an alloy made of bio-compatible material. Oxidized zirconium is called oxinium. These are better than the cobalt chrome implants used until now and can be effective without any replacement for more than 30 years,” said Dr Reddy announcing the achievement to reporters.
The hospital, operational for the past six months, would be officially open on May 2, he said. Oxinium was approved by the FDA (Federal Drug Authority) ten years ago. It would suit patients sensitive to metal, especially nickel, said Dr Synder.
Unlike the current practice of using cobalt chrome on one side and plastic on the other usage of oxinium was of superior strength, with high wear resistance and endurance though it might cost Rs 10,000 to Rs 20,000 more. Cost of replacement surgery for a knee would be Rs 2,00,000 per knee with the cost being Rs 90,000 for the implant per knee, Dr Reddy said.
Stressing the need to remove misconceptions which persisted among people on the success of knee replacement surgeries, Dr Reddy said: “Unlike other surgeries, 98 per cent of the knee replacement surgeries have succeeded. The basic surgical technique is the same for both cobalt chrome and oxinium replacement surgeries.”
The surgery could bring more patients from the West as the same operation cost Rs 15 lakh there, Dr Reddy said. As insurance companies did not pay for the revision surgeries, unlike in the US, patients in India should go for oxinium as it guaranteed near lifetime usage, he added.
The ceramic surface makes oxinium implants 4,900 times more abrasion-resistant than cobalt chrome. It also reduces friction between the implant and the plastic or cartilage surfaces resulting in superior durability over time.
“With the increasing incidence of rheumatic arthritis in younger generation between 20 and 30, they can go for oxinium transplants factoring in the longer usage. Post-surgery patients can even sit on the floor and participate in sports like skiing, he said. Dr A.V. Guruva Reddy has over 20 years' experience in joint replacement surgeries and conducts on an average 1,000 surgeries per annum.
