And it doesn't take much common sense to understand that non-directly related injuries in the same area often have a causal relationship.
I guess I'd be more apt to believe that if the microfracture weren't on the right knee and the chipped/broken kneecap on the left. I think that Greg's microfracture and broken kneecap have about the same degree of causal relationship as Stoudemire's knee injury and his detached retina.
Chaos Theory tells us that when a butterfly flaps it's wings in the amazon, Greg Oden breaks a knee. True story!
I'm guessing you don't really believe the second half of that statement... Getting poked in the eye obviously has nothing to do with structural issues. As for Oden, unless it's an acute injury such as an ACL tear, it is highly likely that any two knee injuries, even on opposite knees, are related. People have bad knees, not a bad knee... None of Oden's three recent knee injuries are sufficiently explained by what happened at the time (i.e. getting off the couch, bumping knees, or jumping), so it's much more plausible that an underlying issue is at play.
not necessarily true. I have only one bad knee. Also, I don't think anyone said that the MF was caused by him getting off the couch, thats when he felt it the first time. And the patella breaking is actually explained by him jumping. I believe that your leg muscle contracts, and pulls on the knee-cap.
And, except for the fact that seismologists agree that the earthquakes (on 8 differerent plates with 2 different plate boundary types) aren't related causally...? Look, the human mind is designed to find causal relationships, patterns. When it sees things, it forms a pattern, a reason why that happened. Even if that reason is "they must be related somehow". It's instinct, way below frontal lobe thinking. It's natural. It's why we thrive as a species. But it produces false positives all the time. Those false positives are usually manifested in little things like small myths (the hot hand) and conspiracy theories (inside job). So feel good: your brain is wired to survive. It's finding connections all over the place. It's also finding some false positives.
