Knee osteoarthritis (OA) develops as the articular cartilage degrades over time, leading to bone-on-bone contact, joint space narrowing, osteophyte formation, and inflammation. Pain, stiffness — particularly in the morning and after rest — reduced range of motion, and difficulty with stairs are the hallmarks.
Knee OA affects over 3 million Canadians and is the leading cause of functional disability in people over 65. Conservative management (physio, weight management, NSAIDs, injection therapy) is the standard of care before surgical options are considered. The waitlist for primary care orthopaedic assessment averages 6–12 months in most provinces; knee replacement waitlists are 12–36 months. The window for self-management is long, and the evidence supports using it well.
The Evidence for Acupoint Stimulation in Knee OA
The 2016 Cochrane review on acupuncture for osteoarthritis (Manheimer et al.) analysed 16 trials with 3,498 participants. The review found moderate-quality evidence that acupuncture produces clinically meaningful pain reduction and functional improvement compared to sham acupuncture, and stronger evidence vs no treatment. Notably, the evidence for knee OA was specifically stronger than for hip OA — partly because knee trials were more numerous and methodologically rigorous.
The OARSI (Osteoarthritis Research Society International) clinical practice guidelines, updated in 2019, include acupuncture as a conditional recommendation for knee OA in patients with comorbidities who cannot tolerate pharmacological options. This is the mainstream international guideline for OA — acupuncture's inclusion reflects the evidence level, not a fringe endorsement.
For acupressure specifically, a 2015 trial published in the Journal of Advanced Nursing (PMID 25329903) found self-acupressure at knee points reduced pain and functional limitation in knee OA patients over 8 weeks compared to controls. Self-application is feasible and effective for the points directly around the knee.
Anatomy and TCM Mapping
In TCM, several meridians converge at the knee. The medial aspect of the knee is governed by the Spleen, Liver, and Kidney meridians — the three yin channels that run up the inner leg. The lateral aspect is governed primarily by the Gallbladder and Stomach meridians on the outer and anterior surfaces. This mapping corresponds reasonably well with the anatomical distribution of knee OA: medial compartment OA (the most common type, affecting the inner joint surface) vs lateral compartment and patellofemoral OA.
Using points on the relevant meridians for your OA distribution pattern makes practical sense — medial compartment pain responds best to medial points (SP9, SP10), lateral compartment pain to lateral points (GB34), and anterior knee/patellofemoral pain to the Xiyan eye-of-the-knee points.
Points for Knee Pain
SP9 / Yinlingquan — Yin Mound Spring
Location: In the depression directly below the medial condyle of the tibia — at the inner knee, follow the tibial bone upward until you reach the concave hollow just below where it widens into the condyle. Press against the bone.
What it does: SP9 is the primary point for medial knee pain, swelling, and fluid accumulation (effusion). It transforms Dampness in TCM — the pathological accumulation of fluid in the joint. For people whose knee pain is accompanied by visible swelling or a "tight, full" sensation in the joint, SP9 is especially relevant. 60–90 seconds. Note: if the knee has significant fluid accumulation (you can see swelling), do not press directly into the swelling — work the points on the margins around it.
ST35 / Dubi + EX-LE5 / Xiyan — Eye of the Knee
Location: These two points form a pair — one medial and one lateral — in the depressions on either side of the patellar tendon (the tendon below the kneecap). With the knee bent at approximately 45 degrees, you'll feel two soft hollows flanking the tendon.
What it does: The "eye of the knee" pair are the most anatomically direct points for knee joint pain — they sit directly at the joint line, level with the joint space. They are used in virtually all acupuncture protocols for knee OA. Apply 60 seconds to each point with the knee slightly bent. These points can be held simultaneously with the thumb and index finger on either side of the tendon.
GB34 / Yanglingquan — Yang Mound Spring
Location: In the depression just anterior and inferior to the head of the fibula — the small bony prominence on the outer side of the upper leg, just below the knee. Press into the depression and slightly upward toward the knee.
What it does: GB34 is the influential point of all sinews (tendons, ligaments, fascia) — it has broad musculoskeletal action across the body. For the knee specifically, it addresses lateral compartment OA, iliotibial band syndrome, and outer knee tightness. 60 seconds per side. If your knee pain is primarily on the outer aspect, this is a primary point.
SP10 / Xuehai — Sea of Blood
Location: On the inner thigh, approximately 2 finger-widths above the superior medial angle of the patella (upper inner corner of the kneecap), in the bulk of the vastus medialis (the teardrop-shaped muscle on the inner thigh).
What it does: SP10 is the "sea of blood" point and has specific action on blood stagnation and inflammation. In OA, the synovial inflammation component — the warmth, swelling, and inflammatory pain — is what SP10 addresses. For people whose OA has a significant inflammatory component (morning stiffness lasting over 30 minutes, swelling, warmth around the joint), SP10 is a key addition. 60 seconds per side.
ST36 / Zusanli — Leg Three Miles
Location: Four finger-widths below the bottom of the kneecap, one finger-width lateral to the tibial crest.
What it does: ST36 is the systemic anti-inflammatory tonic point with the strongest evidence base in acupoint research. Beyond local knee work, ST36 modulates systemic inflammation — IL-6, TNF-alpha, and other inflammatory markers are reduced in acupuncture trials targeting ST36. For OA with a systemic inflammatory component, this point provides benefit beyond what local knee points can achieve. 60 seconds per side.
KD3 / Taixi — Great Stream
Location: Posterior to the medial malleolus (inner ankle bone), in the hollow between the malleolus and the Achilles tendon.
What it does: KD3 is indicated for the Kidney deficiency pattern of OA — the presentation common in older patients, where knee pain is worse at night, accompanied by weakness and a sense of the knee "giving way," and aggravated by fatigue rather than activity alone. In TCM, the Kidneys govern bone, and Kidney deficiency is a primary pathology in age-related OA. If your knee OA fits this pattern (night pain, weakness, worse when tired), add KD3 to your routine. 60 seconds per side.
Positioning and Application
Most knee points are easiest to access seated in a chair with the knee at approximately 90 degrees. ST35/Xiyan (the eye-of-the-knee pair) require the knee slightly bent — between 30 and 45 degrees — to open the joint space and make the depressions accessible. SP9 and SP10 are most accessible with the knee slightly extended (more toward straight) so the muscles are relaxed.
Never apply direct pressure over an actively swollen knee with visible fluid accumulation (effusion). You can see this as a visible fullness or puffiness around the kneecap. Work the distal and proximal points (ST36, KD3, SP6) until the effusion resolves, and avoid the local knee points until the swelling is down.
Frequency and Timing
For OA management, daily practice shows the most consistent evidence. A 10–15 minute session working through the knee points systematically is the target. Two practical approaches that work well: preemptive (before activities involving significant knee load — stairs, long walks, gardening) and recovery (after activity, when the knee is stiff and sore). Both are valid; daily preemptive tends to produce better cumulative outcomes.
Expect 4–6 weeks before assessing whether the practice is working. OA-related pain reduction with acupoint stimulation in positive trials typically reaches measurable levels at the 4-week mark and increases through 8 weeks.
Physio Integration
Quadriceps strengthening is the most evidence-based conservative intervention for knee OA — stronger quads reduce the mechanical load on the knee joint, which directly slows cartilage degradation. Acupressure for pain management and physiotherapy for structural support are complementary tools, not competing ones. Trials comparing combined approaches consistently outperform either alone.
Most Canadian extended health plans cover physiotherapy: Alberta Blue Cross, Sun Life, Great-West Life, and Manulife typically cover $500–1,000/year for physiotherapy services. At $80–120/session, that's 6–12 sessions per year — enough to establish a home exercise programme and have follow-up assessments. Self-acupressure costs nothing and fills the daily gap between appointments.
Acupressure Mats and Knee Pain
Acupressure mats are not well-suited for knee-specific work. The mat's spikes apply general surface stimulation, not targeted point pressure at the knee's anatomically specific locations. Manual point work (your thumb or knuckle at the specific locations above) is substantially more accurate and effective for knee OA. See the general chronic pain acupressure guide for systemic pain management where mats have more applicability.

Acupressure is a complementary self-care practice. It is not a treatment for knee osteoarthritis or any musculoskeletal condition. If you have knee pain with swelling, locking, instability, or progressive worsening, seek medical assessment before attempting self-treatment. Do not apply pressure over a visibly swollen, fluid-filled joint. This page is for informational purposes only and does not constitute medical advice.
