As per a new US report, it has been revealed that joint replacement has become quite coming thing in America. Official data has revealed that one in 20 Americans, more than 50 years of age, has replaced the knees. This is a clear indication that the US population is ageing at fast pace.

Dr. Daniel Berry, who is President of the American Academy of Orthopedic Surgeons and chairman of orthopedic surgery at the Mayo Clinic in Rochester, told that there is great need to know the total number of elderly people who are in the need of joint replacement.

This urgency is due to the fact that if they are not provided joint replacements on time then they are at high risk of developing knee fractures, joint infections and hurt tissues. Joint problem is no more restricted to elderly people as there are many cases where joint replacements surgeries have been conducted on adults.

Berry said that this is also beneficial for them as young adults get joint treatment on time. The number will increase in the coming time and having joint replacement surgery is not enough as many instances have been found where people go for repeated surgeries.

Elena Losina, from the Harvard's Brigham and Women's Hospital, told that joint replacement operation is not something new and dates back to the time of 1970s. With increase in the trend, it has become important that people should take great acre of their health.

Some of the important things they need to take care about them are that they should keep a tab on their weight, and should take vitamin D rich diet and should never give up on their exercise routine. "These data are sobering because we didn't know what an army of people we've created over the last decade ", said Elena.
