Effective Relief for Inner Knee Pain Using Acupuncture

Inner knee pain, often referred to in clinical settings as medial knee pain, is a common issue affecting people of all ages. Whether it’s caused by sports injuries, repetitive strain, or degenerative joint conditions, pain on the medial (inner) side of the knee can significantly impact your mobility and quality of life.

In this article, we’ll explore the anatomy of the inner knee, potential causes, treatment options and how acupuncture can be a safe and effective part of your recovery.

Inner knee pain refers to discomfort located on the medial aspect of the knee joint, which is the side of the knee closest to the midline of your body.

This pain may present as:

• Sharp or dull aching sensations
• Swelling or tenderness
• A feeling of instability or weakness
• Stiffness, especially after rest
• Pain when walking, climbing stairs, or squatting

Pain on the inner side of the knee often results from injury or inflammation involving structures like the medial meniscus, medial collateral ligament (MCL), pes anserine bursa, or joint cartilage.

Several anatomical structures on the inner side of the knee can be involved. Here are some common causes:

1) Medial Meniscus Tear

The meniscus is a C-shaped cartilage that cushions the knee joint. The medial meniscus can tear due to sudden twisting movements, especially in sports or during weight-bearing activities.

2) MCL Injury

The medial collateral ligament stabilises the inner knee. Injury to this ligament usually occurs due to direct impact or forceful knee rotation.

3) Pes Anserine Bursitis

The pes anserinus is the conjoined tendons of the sartorius, gracilis, and semitendinosus muscles. When it is overused due to improper movement mechanics, a small fluid-filled sac near the inner lower part of the knee – this is the pes anserine bursa – becomes inflammed.

4) Knee Osteoarthritis

Degenerative changes in the joint, especially in the medial compartment, can lead to chronic inner knee pain. This is more common in middle-aged and older adults.

5) Repetitive Stress or Biomechanical Imbalance

Long-term strain from activities such as walking, running, or even standing with poor alignment can contribute to medial knee pain.

To properly diagnose medial knee pain, a healthcare professional may perform:

• Physical examination of the knee, assessing tenderness, swelling, and stability
• Range-of-motion tests and orthopaedic maneuvers to evaluate meniscus or ligament involvement

Imaging such as X-rays or MRI for detailed views of bone, cartilage, and soft tissue structures

Treatment plans vary depending on the diagnosis, severity of symptoms, and the patient’s lifestyle or activity level. Common interventions include:

• Rest and Ice: To reduce inflammation and pain in the acute stage
• NSAIDs (Non-Steroidal Anti-Inflammatory Drugs): For temporary pain relief
• Physical Therapy: To strengthen surrounding muscles, improve biomechanics, and support joint function
• Supportive Bracing or Orthotics: Especially in ligament injuries or joint instability
• Corticosteroid Injections: In cases of persistent inflammation

Acupuncture and Traditional Chinese Medicine: As a complementary, non-pharmaceutical therapy

Acupuncture is part of Traditional Chinese Medicine (TCM) and involves inserting fine, sterile needles into specific points to stimulate the body’s natural healing processes. Modern research suggests that acupuncture may help knee pain by:

1. Reduces Inflammation and Modulates Cytokines

Acupuncture has been shown to influence the body’s immune response by downregulating pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α, which are often elevated in conditions like osteoarthritis and bursitis. It may also increase anti-inflammatory mediators, helping to reduce joint inflammation and tissue irritation.

2. Improves Local Circulation and Nutrient Delivery

Needling specific acupoints can enhance microcirculation around the knee joint, promoting better oxygenation and nutrient flow to damaged tissues. This supports tissue regeneration, waste removal, and overall joint recovery.

3. Modulates Central and Peripheral Pain Pathways

Acupuncture activates afferent nerve fibers (A-delta and C fibers), which send signals to the spinal cord and brain, triggering the release of neurotransmitters that modulate pain perception. 

This neural regulation can be very effective at reducing pain signals from the affected knee and may shift pain processing in chronic cases.

4. Relaxes Muscles and Reduces Myofascial Tension

Muscle guarding and soft tissue tightness often develop around a painful or unstable joint. Acupuncture can induce local muscle relaxation, reducing tension in surrounding structures such as the hamstrings, gracilis, and sartorius, which attach near the medial knee.

Trigger point needling or motor point acupuncture techniques may also be used to restore proper muscle tone and movement patterns.

5. Enhances Joint Function and Mobility

Through its combined anti-inflammatory, analgesic, and muscle-regulating effects, acupuncture helps restore functional mobility in the knee joint. This is particularly beneficial for individuals with:

• Medial meniscus injuries
• MCL sprains
• Pes anserine bursitis
• Early to moderate osteoarthritis

Acupuncture is most effective when used as part of a multimodal approach, including movement retraining, manual therapy, and postural correction.

Acupuncture is suitable for individuals experiencing:

• Persistent or recurring inner knee pain
• Side effects from pain medications
• Limited results with physical therapy alone
• Interest in natural or integrative treatment approaches

If your pain is interfering with your lifestyle, daily function, or sleep, acupuncture can be an effective adjunct to your care plan.

During your acupuncture session, our acupuncturist will choose points to target soft tissue restriction, reduce inflammation and promote healing. Your practitioner may choose specific acupoints including some of these mentioned below:

SP9 (Yinlingquan): Located on the inner side of the lower leg, this point is effective at stimulating the tibialis posterior muscle, and releasing tension in the inner aspect of the knee. It is especially effective for restrictions that cause pain in the pes anserinus.

LV8 (Ququan): Found slightly beneath the medial knee crease, this point is used in conjunction with SP9.

Xiyan (Eyes of the Knee): A pair of points that enter deep into the knee joint, helpful in general knee pain and inflammation

SP10 (Xuehai): Traditionally used to invigorate blood circulation, this point is also used to stimulate the VMO muscle, which is weak in most cases of inner knee pain.

Don’t let medial knee pain become a long-term issue. Early intervention can prevent further joint damage and help you regain mobility.
