標題：跳高48吋的練武奇才？小牛新秀DSJ for Real
在今年選秀前，到湖人試訓，傳說跳出了歷史等級的48吋最大起跳度的Dennis Smith Jr.
，過去幾天應該也沒多少人把這句話當真，頂多當成鄉野傳奇，搞不好是選前放的消息，
抬抬自己身價，所以大家看看也就過了。不過好勝心強的DSJ在選秀結束，確定加入小牛
之後，總算也願意自己揭密了。

今天早上視頻流出，媽阿！跨下接360度，OK，不要驚慌，去年Boston Celtics的新秀
Jaylen Brown也幹過，咱門來複習一下。

根據體測數據：
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
所以我們簡單的算，兩人站立的最大摸高差6吋。
Jaylen Brown 16-18歲的時候測試，他的最大跳躍高度約39.5到42吋之間。
所以用數據來做換算，39.5到42吋加上6吋，結果就是45.5吋到48吋之間。
看來DSJ這個48吋應該是確實的，而且比較起來，
DSJ助跑的距離短上許多阿，真是嚇死人的爆發力。
至於DSJ之前經歷過的ACL手術，首先看一下下面這一段話：
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手術確實在這5-7年之間突飛猛進，技術的進步不可同日而語，目前普遍使用的方式是
類似於棒球的Tommy John手術，利用自體或異體的方式移植接近長度與寬度的韌帶過來做
橋接。
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說明，一般來說異體移植有40%的機率可能會排斥，自體移植沒有問
題，大部分取自腱肌腱的一部分，或髕骨肌腱的中心，對菁英運動員來說，腿筋移植可能
會產生問題，可能會感受到不適，大多數的人幾乎不知道，但有些人會注意到差異。目前
移植的擺錘已經從髕骨腱移植到腿筋，並且似乎再次回到使用髕骨腱移植。
不過呢！有趣的來了，咱們討論的這位Dennis Smith Jr.是天生的練武奇才，他多別人一
條阿，所以就完美移植，不只不需要考慮移植之後適應的問題，因為不論長度寬度韌性，
幾乎一模一樣，就像打電動DSJ天生就是多別人一條命，那自動接關只是剛剛好，而且因
為他兩邊都多一條，所以現在拿掉一條，他另一邊還多一條可以用阿，就算再出一次狀況
，還是可以無損接關，根本就是不公平嗎！
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其實正式比賽已經不那麼跳了，自從斷掉ACL之後，多多少少還是有自覺要保護自己，
做為一個同樣受過大傷的籃球愛好者，這天生多幾條命接關真是可遇不可求，好真希望自
己也是練武奇才阿，不過誠摯的建議DSJ灌籃大賽就不用了，沒事可以上籃就不要灌籃，
多打幾年才是王道阿，學學你頭上那個阿北，人家打了20年了阿。
