膝蓋積水老是反覆發作?問題可能不只是膝蓋

這幾週門診來了好幾位膝蓋反覆積水的患者。比較特別的是,他們都沒有明顯的外傷或扭挫傷史——有人只是久未運動,跑個步後膝蓋就腫了起來;也有人並未進行任何劇烈活動,只是連續幾天久坐辦公,起身走動後,竟發現膝蓋腫脹、彎曲受限。

這些患者在來找我之前,已經接受過抽水及基礎的復健電療,但往往在一兩週後又再度出現積水。

積水只是結果,不是問題的根源

在我門診處理膝蓋積水的患者時,我一定會先使用超音波檢查,評估關節腔內的積液狀況,並觀察是否有韌帶、骨骼等結構的損傷。

接著,會透過中醫把脈,結合動作測試與姿態評估,找出造成關節發炎的肌肉失衡來源。

很多人以為「積水在膝蓋,問題就在膝蓋」,但實際上,造成膝關節長期磨損與滑膜發炎的源頭,可能來自臀部、大腿、腳踝等部位的不平衡代償。

針刀鬆解 + 乾針修復,標本兼治

治療上,我會依據患者的體質、病程長短,以及肌肉筋膜的緊繃狀態,設計個別化的治療方案。

在針刀治療方面,我會特別處理膝關節肌(Articularis Genus)與膝前滑囊等處。這些結構常因長期摩擦與緊繃而造成局部滑液發炎,透過針刀的微創鬆解,可有效疏通黏連、降低局部壓力。多數患者在第一次治療後,膝蓋腫脹即能明顯改善,一週回診時常已有顯著變化。

接著,我會使用乾針深入修復相關肌群,例如臀肌、大腿、小腿及足弓。這些部位的張力失衡,往往是導致膝關節負擔過大的幕後黑手。

中藥內服,調理體質助修復

如果病人合併明顯的體質偏差,例如濕重、血虛、風寒濕閉阻等狀況,我也會根據其症型開立中藥,幫助身體調整回正軌。常用的處方包括:獨活寄生湯、當歸拈痛湯、桂枝芍藥知母湯及龍膽瀉肝湯。

總結

對於膝蓋反覆積水的患者來說,重點並不只是「把水抽掉」就好。如果只是反覆抽水、吃消炎藥,卻沒有處理真正造成滑膜發炎的根源,往往只是治標不治本。

當然,也有一小部分患者是合併明確的結構性損傷,如半月板撕裂、韌帶斷裂等,這類情況就需要進一步安排 MRI 等高階影像檢查,並轉介至骨科進行更完整的處置。

但若經過評估屬於功能性積水,或是早期退化、過度使用引起的慢性發炎,中醫的整合式治療,往往能讓這類患者擺脫反覆積水、反覆抽水的惡性循環。


Recurrent Knee Effusion Without Injury? The Real Cause Might Not Be Your Knee

In recent weeks, several patients have visited my clinic for recurrent knee swelling (effusion)—yet none had major injuries. Some developed swelling after jogging for the first time in a while, others simply after prolonged sitting. Many had already tried joint aspiration and basic physical therapy, but symptoms quickly returned.

🔎 Knee effusion is a symptom, not the root problem

At my clinic, I always start with musculoskeletal ultrasound to assess fluid buildup and check for ligament or joint damage. Most of these cases reveal no structural injury, but rather muscle imbalances around the hip, thigh, or ankle. These imbalances overload the knee, causing inflammation and excess fluid.

💉 Minimally invasive treatments: acupotomy and dry needling

Treatment is personalized based on body constitution and tissue condition. I use acupotomy to release tension near the articularis genus muscle and inflamed bursae—often improving swelling within a week.

I then apply dry needling to correct underlying muscle dysfunctions—commonly in the gluteus medius, quadriceps, calf muscles, and foot arch—to address long-term imbalance.

🌿 Herbal medicine for internal regulation

For patients with signs of dampness, blood deficiency, or wind-cold blockage, I prescribe classic Chinese herbal formulas like Duhuo Jisheng TangDanggui Niantong Tang, or Longdan Xiegan Tang to support systemic recovery and reduce inflammation.

🧩 Conclusion: Treat the cause, not just the fluid

Recurrent joint effusion often stems from functional imbalances, not just localized inflammation. Simply draining the fluid and using NSAIDs is not enough. Combining ultrasound assessmentacupotomydry needling, and TCM herbal therapy offers an effective, holistic solution.
