Knee 膝
To say the knee is a hinge joint seems to oversimplify its actual movement: it is a very special joint, in that your lower leg (tibia + fibula) has a minor degree of rotation (see photo) so your foot can turn outward and inward. However, do not think it is like your ankle or hip - it performs flexion extension and a small degree of rotation internally and externally. 除了屈曲伸直，膝關節還有一個幅度小卻重要的方向- 內外旋轉；膝關節不會是一個普通的單方向門骹式關節，但也絕非靈活如腳踝或髋關節（大髀骹）。
To have a healthy knee, you need the followings （健康膝關節由此👇🏼起）:
1. Synchronized movement of your menisci with your tibia 🦴 (小腿脛骨和半月板的活動方向是一致同步）
2. Intact ligaments and muscle tendons with no fibrosis or abnormal tension (韌帶要穩健、肌腱沒有不尋常阻緊張或纖維化）
3. Nerves & blood vessels supplying the knee joint be healthy, capable of smooth gliding throughout knee joint full range of motion (支配膝關節的神經線和血管要在膝頭活動時靈活滑動、神經線要健康）
4. The bones are in good density and alignment (骨頭要健康，沒有骨質疏鬆，位置適當）
Today’s focus is #1 : if the menisci do not move in regards to knee’s movement, with time, the menisci would have tear, or erosion, or degeneration. In internal rotation of lower leg in knee flexed position (only 10 deg, as in photo), the medial meniscus (the bigger C-shape one) should be able to move up (as in photo) at most 10-12mm; in lateral rotation of lower leg in the same position (30-40 deg), the lateral meniscus (the smaller one) should be able to move up to at most 5-6mm.
Your therapist should be able to check this for you to understand if meniscal movement is possibly one of the causes for your knee problem. But of course, the big picture is, there are organs affecting your meniscal movement 🤓. Let’s talk about this later.
今日先討論 #1: 假設半月板不能和小腿骨同步移動、他們就會有撕裂、退化（因為他們像水牛芝士夾在兩塊三文治之間😆）; 在屈膝90度後，小腿內旋大概有10度，內側半月板要向上移動（最多10-12mm）；同一位置，小腿外旋大概有30-40度，外側半月板要向上移動（最多5-6mm）。你的治療師應該要為你檢查你的半月板活動，是否構成你膝關節問題的一部分。當然，宏觀的角度是，原來背後還有內臟器官會影響半月板活動。🤓有緣再談。

脛神經支配 在 動身指南 Getting Started Facebook 的最佳貼文
#案例分享
一位兩週前滑雪跌倒的女性，主訴在尾椎和左側的屁股後側有疼痛感，在走路時（跨大步）、彎腰的時候痛感會加劇（約為六分痛）
#評估
從主訴中跌倒的病史和疼痛的部位可以推估薦髂關節和髖關節都可能是症狀的來源，在步態分析中發現，左腳承重期時，#骨盆後傾、#骨盆往右側偏移、#跟骨內翻、且同時伴隨左屁股疼痛加劇。
髖關節CKC檢查結果為左側臀大肌、半腱肌、股二頭肌長頭lock short。
#治療
腰椎骨盆薦椎排列好了之後，疼痛下降一半，在處理臀大肌、半腱肌、股二頭長頭之後痛感就消失了，走路的也變得順暢。
#結論
「真正」的膕旁肌群必須符合三個條件：
1. 為雙關節肌肉
2. 做髖伸直和膝蓋彎曲的動作
3. 由脛神經支配
故四條膕旁肌只有半腱肌、半膜肌和股二頭長頭為真正的腿後肌（股二頭短頭由總腓神經支配且為單關節的動作肌），半腱肌和股二頭長頭不只連接到坐骨粗隆上，也藉由薦粗隆韌帶來穩定薦髂關節的後側，故 #有薦髂關節的症狀且同時有髖部肌群失能時，除了臀大肌之外，半腱肌和股二頭長頭也是髖部評估的重點。
