I'm sorry my friend, but this simply isn't true. This is an excerpt from an article written in 2013 citing quotes from Dr Andrews (the pope of sports medicine) himself, as well as some statistics from a study written about in a recent medical journal:
-- Below is a comment from Dr. James Andrews on how athletes return from major knee reconstruction:
“They’re all different,” Andrews said. “There’s still a big spectrum in how they heal and how they come back . . . It’s hard to predict recovery from an ACL surgery, and to say that we’re getting them back quicker than we used to would be false information from my standpoint.”
Many don’t come back at all. A 2010 study published in the American Journal of Sports Medicine found that only 63 percent of NFL athletes who had an ACL reconstruction returned to play another game. Roughly two out of three. And two years after ACL surgery, Andrews said, about 55 percent of NFL players are no longer playing in the league. For the majority, an ACL still is pretty synonymous with the end of a career.
So as you can see from one of the most renown orthopedic surgeons in the country, it is a pretty life-altering surgery, especially for a professional athlete. --
And this is for NFL players. It's important to note that association football players and gridiron football players build very different types of muscle. Gridiron players build vast amounts of white muscle for size, a kind that allows them to better compensate for the stresses placed on the joints. Association players' training is more geared towards building red muscle for endurance, and this kind does not provide the protection that white does due to its bulk and more fibrous nature.
So there's two important factors at hand here for why you likely have a misaligned sample from which you've developed your opinion:
1) The media does not tell the stories of the failures to recoup from major injuries. That's depressing, and people don't want to watch it. What spreads like wildfire and gets people talking and watching is the stories of hope, the success stories. Simple media phenomenon.
2) You, like me, are American. We're exposed to more American sports. American sports have become almost entirely based on size, and especially athletes obsessed with the accumulation of that white muscle. Therefore, it is more likely that we see athletes recover than they would from sports in the rest of the world.
This is not due to better modern medicine though bro, it's due to a displaced sample from which we develop our opinions. The fact is, cartilage is what it is. Cartilage is avascular, not great at healing, and was never meant to undertake the athletic demands we place upon it. There is nothing we can do in medicine to change that. Modern rehab techniques are intended to strengthen in areas to compensate for the weakness to fully allow it to heal as optimally as possible, but they can do nothing for that ligament itself.
So I'm sorry my friend, while I heavily respect your opinion specifically, in this case I wish I shared your hope so as to agree with your excitement.
