Knees that dread surgery: first sort out walking, stairs, and squatting
Female, 62. Symptoms for 5 years, both knees (right worse), overweight.
K-L grade III; orthopedics recommended replacement, which she is not ready for. The role of Chinese medicine is to make the years that can still be managed conservatively go better — pain and function are ours; structural change is not within what we promise.
History and prior work-up
Bilateral knee pain for 5 years, difficulty with stairs and squatting. Pain sat around and medial to the patella, with occasional swelling and buckling; morning stiffness under 30 minutes; walking distance on flat ground capped at about 500 meters.
Bilateral knee X-rays showed K-L grade III (right) and II (left); hyaluronic acid intra-articular injection had been tried with short-term benefit; NSAIDs were used; orthopedics recommended right knee replacement, which the patient deferred.
Examination and pattern differentiation
The main pattern is liver-kidney insufficiency with wind-cold-damp bi (painful obstruction), combined with phlegm and stasis obstructing the collaterals. Worsening with cold points to wind-cold, aching weakness with crepitus to liver-kidney insufficiency, swelling and heaviness to phlegm-dampness. The textbook classification of knee osteoarthritis in Chinese orthopedics and traumatology corresponds.
- Both knees mildly swollen, skin temperature not raised, flexion from 100° to 0°, medial joint line tenderness, mild varus alignment.
- Tongue pale and swollen with a white greasy coat; pulse deep and thready; aversion to cold with preference for warmth.
Treatment pathway
- External treatment first: medial and lateral eye-of-the-knee points (Xiyan), Dubi ST35, Xuehai SP10, Liangqiu ST34, Yanglingquan GB34, Yinlingquan SP9, Zusanli ST36, Xuanzhong GB39, Taixi KI3; acupuncture with needle warming or moxibustion (first choice for cold-damp); where swelling is marked, add bloodletting (pricking) or gentle tuina, avoiding forceful passive flexion and extension. Two to three times weekly.
- Herbal decoction as support: for wind-cold-damp, Duhuo Jisheng Decoction; for liver-kidney insufficiency, the intent of Zuogui Pill or Jianbu Huqian Pill; for phlegm and stasis, the intent of Shentong Zhuyu Decoction combined with Erchen Decoction (Two Aged Ingredients). Classical reference: Sun Simiao's Bei Ji Qian Jin Yao Fang and Duhuo Jisheng Decoction. Dosage is set at the in-person consultation.
- Functional training (core): quadriceps isometrics, straight-leg raises, wall sits (angle increasing gradually), gluteus medius work; weight reduction and walking on flat ground matter more than any manual technique.
- Concurrent management: correct use of a knee brace and walking aids, avoiding stairs and deep squatting; intra-articular treatment when necessary (performed by orthopedics).
Re-evaluation
| Timepoint | Stair pain | Rest pain | Flexion range | 6-minute walk | Training adherence |
|---|---|---|---|---|---|
| Baseline at first visit | 7/10 | 2/10 | 100° | 380 m | Not started |
| Week 4 | 5/10 | 1/10 | 110° | 430 m | 4 sessions/week |
| Week 12 | 3/10 | 0–1/10 | 120° | 480 m | Daily |
Follow-up and advice
The goals are framed as 'reduce pain, improve stair-climbing and walking, slow functional decline' — we do not promise cartilage repair. Where late-stage structural damage is severe and life is markedly affected, the orthopedic surgical opinion should still be heard — the role of Chinese medicine is to make the years that can be managed conservatively go better.
