标题：跳高48吋的练武奇才？小牛新秀DSJ for Real
在今年选秀前，到湖人试训，传说跳出了历史等级的48吋最大起跳度的Dennis Smith Jr.
，过去几天应该也没多少人把这句话当真，顶多当成乡野传奇，搞不好是选前放的消息，
抬抬自己身价，所以大家看看也就过了。不过好胜心强的DSJ在选秀结束，确定加入小牛
之后，总算也愿意自己揭密了。

今天早上视频流出，妈阿！跨下接360度，OK，不要惊慌，去年Boston Celtics的新秀
Jaylen Brown也干过，咱门来复习一下。

根据体测数据：
Jaylen Brown 身高6-6.25 穿鞋6-7.5 翼展7-0 最大摸高8-7.5
Dennis Smith 身高6-2 穿鞋6-3 翼展6-3 最大摸高8-1
所以我们简单的算，两人站立的最大摸高差6吋。
Jaylen Brown 16-18岁的时候测试，他的最大跳跃高度约39.5到42吋之间。
所以用数据来做换算，39.5到42吋加上6吋，结果就是45.5吋到48吋之间。
看来DSJ这个48吋应该是确实的，而且比较起来，
DSJ助跑的距离短上许多阿，真是吓死人的爆发力。
至于DSJ之前经历过的ACL手术，首先看一下下面这一段话：
As you read about ACL surgery you will see references to many different
techniques. Our thoughts about how to fix an ACL are changing. Surgery to
replace a torn torn ligament have evolved A LOT over the past 5-7 years.
Older methods did not place the ligament where nature intended it to be.
Many sports docs are very knowledgeable about these latest technique
modifications. This is an area of much interest. You should feel open to
talk with your surgeon about what type of reconstructive surgery they perform.
ACL手术确实在这5-7年之间突飞猛进，技术的进步不可同日而语，目前普遍使用的方式是
类似于棒球的Tommy John手术，利用自体或异体的方式移植接近长度与宽度的韧带过来做
桥接。
We need to use something to reconstruct your new ACL with during surgery.
See our video discussion below on graft choices. We have two broad options:
1. Allograft – tissue from a cadaver, and
2. Autograft – tissue from your own body.
The literature surrounding the use of allografts, especially in young
patients has demonstrated a failure rate approaching 40% in some series.
Bottom line, unless there is a strong reason why you can not use your own
tissue (autograft) then you should probably not use allograft.
In the autograft category we have two main choices- a portion of your
hamstring tendons, or the center of your patella tendon. Both grafts work
well and stand the test of time in a properly performed surgery. A patella
tendon graft certainly hurts more, but that may be worth it in certain
individuals. Research is starting to show that a hamstring harvest in women
may not be a good thing for a high level athlete. Women tend to be
quadriceps dominant… so the front of their thigh is stronger than the back
where the hamstrings are. It stands to reason that we do not want to make
them even more quadriceps dominant by harvesting their hamstring tendons.
In some people, especially elite athletes, a hamstring graft can produce
weakness. While barely perceptible to most, some will notice the difference.
Over my career the pendulum has swung from patella tendon grafts to
hamstrings and it appears to be swinging back once again to patella tendon
grafts. Have a long discussion with your physician.. question why they
suggest a certain graft. This is especially true if considering ACL surgery
with an allograft.
上段文章中也做出了说明，一般来说异体移植有40%的机率可能会排斥，自体移植没有问
题，大部分取自腱肌腱的一部分，或髌骨肌腱的中心，对菁英运动员来说，腿筋移植可能
会产生问题，可能会感受到不适，大多数的人几乎不知道，但有些人会注意到差异。目前
移植的摆锤已经从髌骨腱移植到腿筋，并且似乎再次回到使用髌骨腱移植。
不过呢！有趣的来了，咱们讨论的这位Dennis Smith Jr.是天生的练武奇才，他多别人一
条阿，所以就完美移植，不只不需要考虑移植之后适应的问题，因为不论长度宽度韧性，
几乎一模一样，就像打电动DSJ天生就是多别人一条命，那自动接关只是刚刚好，而且因
为他两边都多一条，所以现在拿掉一条，他另一边还多一条可以用阿，就算再出一次状况
，还是可以无损接关，根本就是不公平吗！
Yet while undergoing surgery, Smith received some surprisingly good news.
Doctors found an extra ligament in his knee, something only 20% of humans
have. The extra ligament would allow him to recover faster than originally
thought, with the initial timetable for recovery being up to ten months.
Smith would go on to see the injury as somewhat of a stroke of good luck,
though, calling it “one of the best things to happen to me before college.”
DSJ其实正式比赛已经不那么跳了，自从断掉ACL之后，多多少少还是有自觉要保护自己，
做为一个同样受过大伤的篮球爱好者，这天生多几条命接关真是可遇不可求，好真希望自
己也是练武奇才阿，不过诚挚的建议DSJ灌篮大赛就不用了，没事可以上篮就不要灌篮，
多打几年才是王道阿，学学你头上那个阿北，人家打了20年了阿。
