baseball but Manny Machado had bad knees - just had abnormal knee structure - he went through 2 surgeries on both knees and hasnt had a problem since.
"The hope was because it was [a] partial [tear on the right side], that it wasn't as severe. The hope was that it would scar down, and we'd be able to get [Machado] back and see how it we went," head athletic trainer Richie Bancells said. "That, in combination with Dr. ElAttrache had always mentioned there was a risk, just given the way that Manny is structured physically, predisposes him to that kind of injury. There was always that risk.

I do think certain players are just injury prone from the way they are born (weak ligaments, abnormal knee structure, etc) plus the way that they play/expose themselves.
Guice is injury prone with his knees. Perhaps he has weak ligaments. Perhaps he doesnt stretch enough or the right way.
When he came back, AP told him he has to trust his knee and that knee and ligament is now stronger than it was before the surgery ...
AP is an example of a guy who has amazing 1% flexibility and laticity ... his knee bent last year in a way that any other player would have a torn ACL. he limped throughout the game but played. Guice would have died if that happened to his knee.
