Robert Walter Beeney was unable to walk due to a stiff hip when he landed in India January 24. Twenty days later, he not only recovered after a rare hip replacement surgery at Apollo Hospital here but also visited the famous Taj Mahal in Agra after that.

The 64-year-old real estate consultant from San Francisco underwent successful surface replacement surgery using the anatomic surface replacement (ASR) hip system January 27, reportedly becoming the first US national to come to India for the treatment.

Another patient from Florida will be landing in Chennai for a similar procedure at the Apollo Hospital there later this week.

A team of doctors, led by orthopaedic surgeon Vijay Bose, carried out the procedure for Beeney.

Jayaramchander Pingle, a member of the medical team, told a news conference on Tuesday that while in the conventional hip replacement surgery, the total hip was replaced, in the new system, the patient's original head and neck of femur were preserved and only their surface is replaced with metal on metal articulation.

With the use of very advanced metallurgy in this device, the wear and tear is reduced to a fraction in the artificial joint as opposed to the conventional total hip replacement.

Another advantage of the latest procedure is that in the event of any problem that may occur in the long term, the conventional total hip replacement can be done at a later stage.

Beeney, who came to know about the procedure in India through the Internet, said that since this was not yet cleared by the US Food and Drug Administration, he decided to come to India.

"This is despite the fact that the device that is fixed in the hip is made in the US," he said.

He also had other options like going to Britain or Belgium for treatment. "But I preferred India as the treatment costs there are huge," he said.

The treatment in India cost him $6,600 (Rs 300,000) while the same as a part of clinical trial in US would have cost $24,000. Even in Britain, where this procedure was first developed a few years ago, it would have cost 12,000 pounds.
