五积散（见上文）
十全大补汤 治疗气血两虚的证候
人参、白术、茯苓、炙甘草、熟地黄、当归、白芍、黄芩（炙）、肉桂（各一钱），川芎（五分），加大枣同服。
（孙思邈之孙孙心典）按语：鹤膝风，是指小腿纤细而膝盖肿胀的病证。初起时有发热、头痛等症状，适宜使用五积散加松节，或者大防风汤、三气饮之类的方剂，也可以间隔送服一钱活络丹，或者用八味丸、六味丸加入鹿茸、牛膝之类的药物进行调补。
《内经》说：“膝是筋的府库，如果屈伸不能，说明筋将要衰败了。”薛己说：这多半是风邪乘虚侵入三阴经所致，治疗方法以温补肝肾为主，如果无效，就必须温暖脾胃。另外有两种外治法，不可不知道。一种是用芥菜子敷法，治疗初起时漫肿不红、屈伸不便的患者，在溃破之前，用陈年的芥菜子研成细末，用姜汁、葱涕调和后涂抹，经过一个时辰（约两小时），患处起泡，泡干脱皮后即可自愈。另一种是用雷火针法，治疗风、寒、湿留滞于筋脉，剧烈疼痛不止的情况，用蕲艾五钱、丁香五分、麝香三分，混合研匀装入纸筒中，在痛处衬垫四、五层布，对着火淬烤数十遍，以筋脉活动自如为限度。但是这两种方法，一旦脓液形成就不可使用了。
喻嘉言说：“鹤膝风，就是风、寒、湿痹阻于膝盖的病证，如膝盖骨头日渐肿大，上下肌肉日渐枯瘦，此时不可以直接治疗膝盖，而应先滋养气血，使肌肉得到滋润荣养，然后再治疗膝盖。”这与治疗偏枯（半身不遂）的病症大同小异，即灌溉那些尚未枯瘦的部位，使气血流通恢复荣润。倘若不懂这个道理，只用麻黄、防风等疏散风邪的药物，很少有不导致病情更加枯败的。所以治疗鹤膝风的人如果急于攻逐痹阻，必然会导致足部痿废不能使用。
Wuji San (see above)
Shiquan Dabu Tang (Complete Ten Tonifying Decoction) treats syndromes of deficiency in both Qi and Blood.

(Sun Xindian, grandson of Sun Simiao) Commentary: He Xi Feng (Crane's Knee Wind) refers to a condition where the lower legs are thin while the knees are swollen. In the initial stage, symptoms such as fever and headache may appear; it is appropriate to use Wuji San added with Songjie (Pinus node), or formulas such as Dafangfeng Tang (Great Wind-Expelling Decoction) or Sanqi Yin (Three-Qi Drink). Alternatively, one may administer Huoluo Dan (Meridian-Activating Pill) at intervals, or use Bawei Wan (Eight-Ingredient Pill) or Liuwei Wan (Six-Ingredient Pill) added with Lurong (Deer Antler Velvet) and Niuxi (Achyranthis Bidentatae Radix) for tonification and regulation.
The *Classic* states: "The knee is the mansion of the sinews; if flexion and extension are impossible, the sinews are exhausted." Xue Ji stated: This is mostly caused by wind pathogens invading the Three Yin meridians due to deficiency. The treatment method should focus on warming and tonifying the Liver and Kidney. If ineffective, warming the Spleen is necessary. Additionally, two external treatment methods must be known. One is the Mustard Seed Poultice method, used for initial swelling without redness and difficulty in movement. Before ulceration occurs, old mustard seeds are ground into fine powder and mixed with ginger juice and scallion sap for topical application. After one fu period (approx. two hours), blisters will form at the affected site; when the blisters dry and the skin peels off, the condition heals spontaneously. The other is the Lei Zhen (Thunder Needle) method, used for severe, unceasing pain caused by the stagnation of wind, cold, and dampness in the sinews. Use 5 qian of Qiai (Artemisia argyi from Qichun), 0.5 qian of Dingxiang (Caryophylli Flos), and 0.3 fen of Shexiang (Moschus), grind them evenly together, and pack them into paper tubes. Place four or five layers of cloth over the painful area, and apply the heated tube to quench the area dozens of times until the sinews regain mobility. However, these two methods are contraindicated once pus has formed.
Yu Jiayan said: "He Xi Feng is essentially Bi syndrome (obstruction) of wind, cold, and dampness in the knee. As the knee bone enlarges daily and the muscles above and below waste away, one should not directly treat the knee first. Instead, one must first nourish Qi and Blood so that the muscles become moistened and flourishing, and only then treat the knee." This is largely similar to treating Pian Ku (hemiplegia/paralysis of one side); it involves irrigating the parts that have not yet wasted away, allowing Qi and Blood to circulate and recover their nourishment. If this principle is not understood, and one merely uses wind-dispelling herbs like Mahuang (Ephedrae Herba) and Fangfeng (Saposhnikoviae Radix), the condition will rarely fail to deteriorate further. Therefore, those who treat He Xi Feng and rush to attack the Bi obstruction will inevitably cause the foot to become flaccid and unusable.
