If your knee’s been giving you trouble, the last place you’d think to look for relief is your elbow. But there’s a technique in Chinese medicine that does exactly that: easing knee pain by working a point near the opposite elbow, called LI11 (Quchi).
What is LI11, and where is it?
LI11 sits at the outer end of your elbow crease, found by bending your arm to a right angle. It’s the final point on the Large Intestine channel, and it’s one of the most-used points in Chinese medicine — traditionally applied to clear heat, move Qi and Blood, and treat elbow and arm conditions like tennis elbow.
Why would an elbow point help a sore knee?
Because the two joints are treated as mirrors of each other. Acupuncture systems built around body correspondences — often grouped under the “Balance Method” — map the arm’s joints onto the leg’s: shoulder to hip, elbow to knee, wrist to ankle.
The elbow and knee are both large hinge joints, and LI11 sits on the arm’s Yang Ming channel, which pairs functionally with the Yang Ming channel that runs straight through the knee. Following that logic, a sore right knee can be worked through the left elbow, and vice versa. Practitioners lean on this when a joint is too inflamed, swollen, or simply too sore to touch directly.
What does the research say?
A pilot randomised controlled trial in the Journal of Pain Research tested this directly. Researchers compared needling local knee points, needling LI11 alone, and combining both, in patients with knee osteoarthritis.
At four weeks, the combined group had the best response rate at 85%. LI11 alone still beat local points on their own — 71% versus 52%. The authors’ takeaway: LI11 is a genuinely useful option, not just a theory.
Can you try this yourself at home?
You can, with the right expectations. Needling by a practitioner is what the study above actually tested, and that’s still the more effective approach. But firm acupressure on LI11 is a safe, simple thing to add between sessions.
Bend your elbow to a right angle. Run your finger along the crease on the thumb side of your arm to its outer end, near the bony point of your elbow — that’s LI11. Using your opposite thumb, press firmly in small circles for one to two minutes, working the side opposite your sore knee. A few times a day is plenty.
What else causes knee pain in Chinese medicine?
Rarely just the knee itself. Chinese medicine usually traces it to one of three patterns: Bi syndrome, where Wind, Cold or Damp settle into the joint; Kidney and Liver deficiency, which weakens the tendons and bones as we age; or Blood stasis left over from an old injury.
That’s why an assessment matters before treatment. LI11 is one tool in the kit, not a stand-alone fix — the right plan depends on which of those patterns is actually driving your knee pain.
If your knee’s been nagging at you for a while, it’s worth getting it properly looked at rather than guessing. Book a consultation and we’ll work out what’s actually going on. You can also read more about our approach to pain management for the full picture beyond this one point.
