Knee replacement is increasingly being done all over the world. A few years back once thought to be very complex surgery and was performed by only a few well-known, established, foreign-trained knee replacement surgeons. Osteoarthritis is the most common indication for one to undergo knee replacement surgery.
According to reports and studies about 13% of women and 10% of men above the age of 60 years suffer from knee arthritis. These numbers are constantly increasing due to increasing life expectancy and an increasing tendency for obesity. In simple terms millions are suffering from knee arthritis today and that number will only increase.
Osteoarthritis is one of the most common conditions that leads to disability in elderly. Initially arthritis was thought to be a condition in the more affluent western countries. But with the increasing prosperity in the 2nd and 3rd world countries, lifestyle diseases have increased to epidemic proportions.
Patients with osteoarthritis are at a higher risk of mortality mainly because of disability caused due to severe pain which inturn leads to invitation of other lifestyle diseases such as diabetes, obesity, cardiovascular disease etc.
More and more knee replacement surgery is being done on the younger population due to increasing incidence in younger people especially due to obesity. Though knee arthritis starts in the joint cartilage but slowly it involves other components and disturbs the mechanism of weight-bearing and walking.
