60 million cases of osteoarthritis in India by 2025

"Such diseases lead to complete disability of the knee. If the pain is not relieved by medication or physiotherapy for long, a person may be bedridden in the long run. So, surgery is advisable," he said.

Osteoarthritis occurs when there is damage in and around the joints that the body cannot fully repair. The exact causes are not known but there are several factors thought to increase the risk of developing the condition. According to doctors, though the current solution for osteoarthritis is surgery -- transplant -- only 10 percent of the Indians undergo it due to fear of late recovery.

Nirad vengsarkar, consultant orthopedic joint replacement surgeon at the Lilavati and Breach Candy Hospital, said: "Women are more prone to suffer from osteoarthritis because of weaker bone and muscle strength in women."

"Come 2025 and India is likely to notice an endemic of osteoarthritis with about 80 percent of the 65 and above population in the country suffering with wear and tear of joints. Forty percent of these people are likely to suffer from severe osteoarthritis, which will disable them from daily activities."

The reason behind the onset of this endemic is said to be increasing longevity of Indians. By 2020, the number of 65 and above population in India is likely to be about 177 million, whereas India had 100 million people in this age group in 2010.
