曰∶厥阴之厥，好卧屈膝，阴缩肿， 内热。李东垣曰∶脚膝痿软，行步乏力或痛，乃肝肾二经伏热。王海藏
曰∶木瓜入肝，故益筋与血，病腰肾脚膝无力者不可缺也）。又属足太阴脾经、阳明胃经（《灵枢》曰∶足太

经；内廉膝曲横纹头，属足厥阴肝经；内前廉，属足太阴脾经）。
（膝盖骨也，又名为连骸骨）统属足厥阴肝经（《素问》曰∶刺膝膑，出液为跛。注∶膝
为筋府，筋会于膝中，液出筋干，故跛也）。〔内廉〕属足太阴脾经。〔外廉〕属足阳明胃经（《素问》曰∶

【骸关附】（大腿下方与膝盖上方相接的部位。膝盖骨解开的地方称为骸关）主要归属于足厥阴肝经和足少阴肾经（《素问》说：厥阴经发生厥逆，患者喜欢躺着并弯曲膝盖，出现生殖器收缩、肿胀以及体内发热等症状。李东垣说：脚膝痿软无力，行走乏力或疼痛，这是肝肾两经潜伏热邪所致。王海藏说：木瓜入肝经，因此能滋养筋脉和血液，治疗腰肾及脚膝无力的病症时不可缺少它）。另外也归属于足太阴脾经和足阳明胃经（《灵枢》说：足太阴脾经的经脉，上行至大腿内侧前缘，进入腹部。该经所生的疾病包括不能平卧、强行站立时股部和膝部内侧肿痛厥冷。又说：足阳明胃经的筋脉，向上结聚于膝盖外侧）。还归属于足少阳胆经（《灵枢》说：足少阳胆经的筋脉，沿小腿外侧上行，结聚于膝盖外侧，其病症表现为膝盖无法屈伸。《素问》说：少阳经引起的腰痛，应针刺成骨顶端出血。成骨，是指膝盖外侧单独突起的那块骨头，夏季不宜见血。沈承之说：膝盖外侧的辅骨，属于足少阳胆经；外侧前缘，属于足阳明胃经；内侧膝盖弯曲处的横纹头，属于足厥阴肝经；内侧前缘，属于足太阴脾经）。
（即膝盖骨，又名连骸骨）主要归属于足厥阴肝经（《素问》说：针刺膝盖膑骨部位，若流出液体则会导致跛行。注解说：膝盖是筋的府库，筋会合于膝中，如果液体流出导致筋干，所以会造成跛行）。【内侧缘】归属于足太阴脾经。【外侧缘】归属于足阳明胃经（《素问》说：针刺散脉，位于膝盖前方骨肉之间的络脉外侧束脉，分为三条。注解说：络脉在外侧，则是足太阴脾经的络脉，颜色青紫可见。《灵枢》说：足阳明胃经的经脉，抵达伏兔穴，下行至膝盖膑骨中间。该经所生的疾病包括膝盖膑骨处肿痛）。
（膝盖后方的弯曲处，即委中穴所在的区域）主要归属于足少阴肾经（《灵枢》说：足少阴肾经的正气，到达腘窝中，别走足太阳膀胱经而相合。又说：肾脏有邪气，其气体会停留在两腘窝中。《素问》说：膝盖疼痛如同分离感，应治疗巨阳经和少阴经的荥穴。注解说：疼痛且感觉膝盖如别离者，则治疗足太阳膀胱经和足少阴肾经的荥穴。足太阳膀胱经的荥穴是通谷穴；足少阴肾经的荥穴是然谷穴）。另外也归属于足太阳膀胱经（《灵枢》说：足太阳膀胱经的筋脉，沿脚跟结聚于腘窝中。又说：足太阳膀胱经的经脉，发生变动时会病发腘窝处像被捆结一样。又说：腘窝中外侧缘，名叫委阳，是足太阳膀胱经的络脉。手少阳三焦经，是三焦在足少阳胆经和足太阳膀胱经中的历络，也是足太阳膀胱经的别络，上行至内踝上五寸处，别出贯穿腘肠肌，出于委阳穴）。同时也兼属冲脉（《灵枢》说：冲脉与足少阴肾经的大络，沿大腿内侧前缘斜行进入腘窝中）。
[Haiguan (Knee Joint) Appendix] (The area where the lower thigh meets the upper knee. The junction of the knee bones is called Haiguan.) It primarily belongs to the Foot Jueyin Liver Meridian and the Foot Shaoyin Kidney Meridian (*Suwen* states: In Jueyin Jue, patients prefer lying down with bent knees, experiencing genital retraction, swelling, and internal heat. Li Dongyuan states: Flaccidity and weakness of the feet and knees, fatigue or pain in walking, are caused by latent heat in the Liver and Kidney meridians. Wang Haicang states: Mu Gua (Fructus Chaenomelis) enters the Liver Meridian, thus benefiting sinews and blood; it is indispensable for treating weakness of the waist, kidneys, and knees.) Additionally, it belongs to the Foot Taiyin Spleen Meridian and the Foot Yangming Stomach Meridian (*Ling Shu* states: The Foot Taiyin Spleen Meridian ascends along the anterior medial aspect of the thigh and leg, entering the abdomen. Diseases generated by this meridian include inability to lie flat, swelling and coldness in the medial thigh and knee when standing forcibly. It also states: The sinews of the Foot Yangming Stomach Meridian ascend and knot at the lateral aspect of the knee.) It also belongs to the Foot Shaoyang Gallbladder Meridian (*Ling Shu* states: The sinews of the Foot Shaoyang Gallbladder Meridian follow the lateral aspect of the leg and knot at the lateral aspect of the knee; their disease manifests as inability to flex or extend the knee. *Suwen* states: For Shaoyang-type lower back pain, bleed the end of Chenggu (Chenggu bone). Chenggu refers to the solitary protruding bone on the lateral aspect of the knee; bleeding should be avoided in summer. Shen Chengzhi states: The fibula (auxiliary bone) on the lateral aspect of the knee belongs to the Foot Shaoyang Gallbladder Meridian; the anterolateral aspect belongs to the Foot Yangming Stomach Meridian; the head of the transverse crease at the medial flexion of the knee belongs to the Foot Jueyin Liver Meridian; the anteromedial aspect belongs to the Foot Taiyin Spleen Meridian).
(Refers to the Patella, also known as Lianhai Bone.) It primarily belongs to the Foot Jueyin Liver Meridian (*Suwen* states: Needling the patellar region causing fluid discharge leads to claudication. Commentary: The knee is the mansion of sinews, where sinews converge; if fluid discharges, sinews dry out, leading to claudication.) [Medial Aspect] belongs to the Foot Taiyin Spleen Meridian. [Lateral Aspect] belongs to the Foot Yangming Stomach Meridian (*Suwen* states: Needling Sanmai vessels located between the muscle and bone anterior to the knee, specifically the collateral vessels binding the lateral aspect, divided into three branches. Commentary: The collateral vessels on the lateral aspect refer to the visible cyanotic collaterals of the Foot Taiyin Spleen Meridian. *Ling Shu* states: The Foot Yangming Stomach Meridian reaches Futu, descends through the middle of the patella. Diseases generated by this meridian include swelling and pain in the knee and patella).
(The posterior flexure of the knee, corresponding to the location of Weizhong Acupoint.) It primarily belongs to the Foot Shaoyin Kidney Meridian (*Ling Shu* states: The proper qi of the Foot Shaoyin Kidney Meridian reaches the popliteal fossa, diverges to join the Foot Taiyang Bladder Meridian. It also states: When pathogenic factors reside in the Kidneys, their qi remains in the two popliteal fossae. *Suwen* states: For knee pain resembling separation, treat the Ying-Spring points of Juyang (Foot Taiyang) and Shaoyin. Commentary: For pain feeling like separation in the knee, treat the Ying-Spring points of the Foot Taiyang Bladder Meridian and Foot Shaoyin Kidney Meridian. The Ying-Spring point of the Foot Taiyang Bladder Meridian is Tonggu; the Ying-Spring point of the Foot Shaoyin Kidney Meridian is Ran Gu.) Additionally, it belongs to the Foot Taiyang Bladder Meridian (*Ling Shu* states: The sinews of the Foot Taiyang Bladder Meridian follow the heel and knot in the popliteal fossa. It also states: Movement disorders of the Foot Taiyang Bladder Meridian cause symptoms such as a knotted sensation in the popliteal fossa. It also states: The lateral outer aspect of the popliteal fossa is named Weiyang, which is the collateral vessel of the Foot Taiyang Bladder Meridian. The Hand Shaoyang Sanjiao Meridian acts as the traversing collateral for the Foot Shaoyang Gallbladder and Foot Taiyang Bladder meridians; it is a branch of the Foot Taiyang Bladder Meridian, ascending five cun above the ankle, diverging to penetrate the gastrocnemius muscle, and emerging at Weiyang Acupoint.) It also concurrently belongs to the Chong Mai (Penetrating Vessel) (*Ling Shu* states: The Chong Mai and the large collateral of the Foot Shaoyin Kidney Meridian follow the anteromedial aspect of the thigh, obliquely entering the popliteal fossa).
