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. 医生并不是刻意移除他的ACL，而是修复失败 2. 他的ACL逐渐退化後消失，但因为是渐进式的过程，他的周边肌群得以适应并强化， 如果是手术移除的话他可能就爆了 3. 长期下来可能造成骨关节炎 http://goo.gl/8iFGc (骨关节炎的定义跟成因) 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缓冲效果较好的落地方式， 或者纯粹他就天生神力周边肌群的回复比其他人更快 2. 他是O型腿，而O型腿对於ACL的倚赖比较没那麽高 http://goo.gl/sSV2H (有用吗?) 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. 其他没有ACL的运动员案例： 2008年 San Diego Chargers 的四分卫 Philip Rivers 把膝盖搞爆了之後， 拖着烂掉的ACL打完总冠军战，然後开始复健人生； Pittsburgh Steelers 的接球员 Hines Ward 在幼年时因受伤而逐渐丧失ACL， 不过同样因为是渐进式的过程所以连他自己都没发现自己「少根筋」。 --
