I have a feeling this will become increasingly more normal. However, one issue that concerns is the athletes that have had it done. I don't know anything about medicine or surgery, but it seems like this prodcedure is for people that have been in the trenches. Years and years of wear and tear from hundreds, maybe even thousands, of games played.
Now we know Bynum's knee is a concern, and it was definitely worth the risk. But should him having this procedure be viewed as "Hey, who cares? It benefits him and a lotta people are doing it." Or "jesus he's 10 years younger than those other dudes. Is this indicative of more trouble to come soon?"
I'm not that worried, and I still think this is the greatest thing to ever happen. However, I was wondering if people with any medical knowledge could give some insight as to negative possibilities in Bynum's future...just to be comprehensive.
