What is a knee replacement surgery and how safe is it for one to undergo it? - Sreemathy Saran, Mambalam
Total knee replacement surgeries are usually conducted on patients suffering from age-related issues and involves replacement of natural joints with artificial ones. Today, more and more patients are coming up for knee replacement surgeries as early as in their mid-50s, due to a growing need for active and pain free life. When the implant wears out or develops a problem, patients are required to undergo a second surgery to replace the existing implant, which is referred to as revision surgery.

Why do men accumulate fat around the waist? - Joy Peter
It is not true that men alone accumulate fat around waist, women also do accumulate. But men have the preponderance due to hormonal activity. Generally, men have high level of testosterone when compared to women that is one of the reason for fat around waist. Women also do accumulate when oestrogen level decreases and testosterone level increases in special conditions.
