Increasing population age = more joint replacements

There's another thing that I should have mentioned in my previous post. According to WebMD, hip replacements are expected to rise 174% in the next 20 years, and knee replacements are expected to rise by as much as 673%. That is an astronomical increase in joint replacement surgeries! This relates back to my previous post, when I talked about the increasingly active lifestyle that today's older generations are living. The knee replacement rates are particularly indicative of this. A total knee replacement is frequently performed on an individual who has been active for a lifetime, and consequently has done damage to the knees. This is unavoidable for many active people. Eventually joints wear out, but luckily we have great replacement technology. Total knee replacements can be expected to last for upwards of twenty years without any significant degradation. Of course, it is always possible for an extremely active and young individual who gets a knee replacement to have a revision later without much hassle.
