Then, over time, Blair's ACLs deteriorated to the point of disappearance. Since this was a gradual change, his muscles and other ligaments could have adapted slowly to the added strain. Without such an adjustment period—if his doctors had simply cut out the ligaments, for example—it's likely he would have injured himself on the court quite rapidly. Blair is now thought to face a higher risk of damaging his knees (especially his meniscus) than athletes with repaired ACLs—and he may end up with osteoarthritis. 1. 醫生並不是刻意移除他的ACL，而是修復失敗 2. 他的ACL逐漸退化後消失，但因為是漸進式的過程，他的週邊肌群得以適應並強化， 如果是手術移除的話他可能就爆了 3. 長期下來可能造成骨關節炎 http://goo.gl/8iFGc (骨關節炎的定義跟成因) Another athlete with Blair's deficiency wouldn't necessarily be capable of operating at such a high level. It's possible that Blair, without consciously intending to do so, has found a way to jump and land that's less harsh on his knees. Or that his other ligaments are particularly resilient. Anatomy may also have something to do with his success. Knock-kneed types are more dependent on their ACLs than the bow-legged. 1. 另外的可能性是他找到了緩衝效果較好的落地方式， 或者純粹他就天生神力週邊肌群的回復比其他人更快 2. 他是O型腿，而O型腿對於ACL的倚賴比較沒那麼高 http://goo.gl/sSV2H (有用嗎?) Blair is not the first professional athlete to play with a missing ACL. In 2008, San Diego Chargers quarterback Philip Rivers blew out his right knee but played with a completely nonfunctional ACL in a conference championship game against the New England Patriots. The Chargers lost, and Rivers underwent an extensive reconstructive operation. Pittsburgh Steelers wide receiver Hines Ward is missing the ACL in his left knee—the result of a bike accident during childhood. Like Blair, he didn't realize the deficiency until he left college to go professional. 其他沒有ACL的運動員案例： 2008年 San Diego Chargers 的四分衛 Philip Rivers 把膝蓋搞爆了之後， 拖著爛掉的ACL打完總冠軍戰，然後開始復健人生； Pittsburgh Steelers 的接球員 Hines Ward 在幼年時因受傷而逐漸喪失ACL， 不過同樣因為是漸進式的過程所以連他自己都沒發現自己「少根筋」。 --
