大家好,小弟和幾個朋友的團隊https://goo.gl/RCiPF5 剛成立,我們致力於推廣健康運
動的文化。有興趣歡迎參觀與分享!
大家都知道前陣子雷帝(KD, Lady)被喳喳一個move弄傷了膝蓋,幫QQ
而勇士近十戰也只打出了五勝五負的糟糕戰績,反觀KD離開的舒適圈在沒有他的情況下依
舊打出了>>>>五成勝率的戰績,果然舒適。
好啦今天是來酸勇勇的,不是,今天是來借KD的傷勢讓大家了解自己的膝蓋,以及讓大家
有機會能預防運動傷害的。

再來看看他傷勢的診斷。
節錄andy大大的文章:
直接翻譯外電原文大意大概是MRI結果出來,顯示為第二級內側副韌帶扭傷及脛骨挫傷。

這是我們人類膝蓋的側面觀,在影片當中我們可以看到喳喳倒地之後,直接撞擊到了KD的
脛骨,造成了一個膝關節過度伸直(knee hyper-extension)的動作。

至於膝關節過度伸直會發生甚麼事情呢?
http://imgur.com/IWMmKU4
這是我們膝蓋裡面的軟組織,右邊是內側,左邊是外側。
其實當膝關節過度伸直發生時,通常會是後十字韌帶受力最大;然而這次KD受撞擊的角度
跟站姿,我們不能排除前十字韌帶(Anterior cruciate ligament, ACL)有可能斷裂,再
來才是內側副韌帶(medial collateral ligament, MCL)以及內側的半月板(medial
meniscus),以上這三者常常被合稱為ACL以及他的不快樂夥伴(unhappy triad),因為他
們常常一起壞掉。
對KD來說,值得慶幸的是ACL並沒有受傷(如果報告沒嘴砲的話),因為根據芝加哥骨科和
運動醫學名醫Dr. John Brna的說法,對運動員來說,ACL是沒有所謂的部分斷裂
(partial tear)的,因為當ACL受傷,整個生物力學都會改變,這樣的ACL並沒有辦法應付
高強度的運動競技,所以一定要接受手術。
不過我今天其實重點並不想放在MCL怎麼受傷的,因為膝蓋被折成那樣,每個人都知道韌
帶有可能受傷。
所以今天我的重點比較想放在為什麼離開舒適圈的KD為什麼膝蓋會被折成那樣。
或是這樣的運動傷害有可能避免嗎?

這是撞擊瞬間的截圖。
我們可以看到不舒適的KD正專心的注意球的動向,完全沒有注意到喳喳壞壞。
如果這時喳喳撞到的是他的右膝,也許傷害並不會發生。
http://imgur.com/a/zrE1B
我們可以看到KD在這瞬間左腳因為鞋子的摩擦力所以是被釘在地上的,而髖關節也明顯是
在發力或是緊繃的狀態,也就是說沒有一個關節能做出代償的動作抵銷掉膝蓋的受力。
如果是撞到右膝,右腳明顯已經準備離開地板,在撞擊的瞬間可以抬離地面,讓膝關節過
度伸直的狀態解除,那運動傷害也許不會發生。
在下肢的傷害(或是運動)中,我們的腳踝、膝蓋以及髖關節,永遠是一起作用的,在KD這
個case中,由於腳踝已經被鞋子的摩擦力釘在地上,唯一能拯救他的,只能是他的髖關節
了。如果在撞擊的瞬間,他的髖關節可以做出屈曲(flexion)並且順勢往後倒的話,這樣
撞擊的力量也許就能夠被抵銷。
http://imgur.com/sB0NBPL
但是如果我們很仔細看影片的話,我們會發現KD的髖關節在被撞擊的瞬間幾乎是紋風不動
的,也許是來不及反應,但以我們的觀點來說,我們會懷疑KD的髖關節也許柔軟度是有些
問題的。
OK,由上述的動作分析我們可以發現一件事情—KD的髖關節可能有些緊繃。
也就是說,在他的復健中,我們不能只完全專注在他的MCL傷勢,還有另外一個重點項目
就是要確定他的髖關節是強壯而柔軟的,如果不是,那麼KD將不能馬上回到球場,不然其
他的傷勢一定會出現。
我相信他的髖關節檢查之後應該會有些問題,不然其實這種傷害不該這麼容易發生。
頂級運動員的身體應該能馬上做出反應,避免自己傷害。

可以在遭受外力之後馬上做出適當的反應分散掉身體各部分的受力。
或是這些照片也可以

說了這麼多,其實就是想提醒大家,當運動傷害發生時,請不要覺得很理所當然,而是要
尋找發生的原因,一點想法,謝謝大家。
