The Effectiveness of Acupuncture for Knee Pain Relief

“For individuals dealing with knee pain symptoms from injury and/or arthritis, can incorporating an acupuncture and/or electroacupuncture treatment plan help in pain relief and management?”

Acupuncture For Knee Pain

Acupuncture involves inserting very thin needles into the skin at specific acupoints on the body. It is based on the premise that the needles restore the flow of the body’s energy to activate and promote healing, relieve pain, and help the body relax.

• Acupuncture can help address various health conditions, including knee pain caused by arthritis or injury.
• Depending on the type and severity of pain, treatments can help reduce the pain for days or weeks.
• Acupuncture is often used as a complementary therapy – treatment in addition to other treatment or therapy strategies like massage and chiropractic.

Acupuncture Benefits

Knee pain caused by osteoarthritis or injury can reduce flexibility, mobility, and quality of life. Acupuncture can help provide relief.

When the acupuncture needles are placed on the body, a signal is sent along the spinal cord to the brain, which triggers a release of endorphins/pain hormones. Medical researchers believe this helps reduce pain. (Qian-Qian Li et al., 2013) Acupuncture also helps decrease the production of cortisol, a hormone that helps control inflammation. (Qian-Qian Li et al., 2013) With reduced pain sensations and less inflammation after acupuncture treatments, knee function and mobility can be improved.

• Various factors play a role in the pain relief experienced from acupuncture. Some evidence suggests that an individual’s expectations may impact the results of acupuncture treatment. (Stephanie L. Prady et al., 2015)
• Researchers are currently assessing whether the expectation that acupuncture is beneficial contributes to a better outcome after treatment. (Zuoqin Yang et al., 2021)
• In 2019, acupuncture was recommended in treating knee osteoarthritis in the American College of Rheumatology/Arthritis Foundation guidelines for hand, hip, and knee osteoarthritis pain management. (Sharon L. Kolasinski et al., 2020)

Research

• Different clinical studies support acupuncture’s ability to help in knee pain relief and management.
• One study found that acupuncture helps manage various conditions that cause chronic pain. (Andrew J. Vickers et al., 2012)
• A scientific review analyzed previous studies on pain management interventions after knee surgery and found supporting evidence that the treatments delayed and reduced the use of medications for pain relief post-surgery. (Dario Tedesco et al., 2017)

Osteoarthritis

• A systematic review analyzed randomized control studies to determine whether or not acupuncture reduced pain and improved joint function in individuals with chronic osteoarthritis knee pain. (Xianfeng Lin et al., 2016)
• Individuals received six to twenty-three weekly acupuncture sessions for three to 36 weeks.
• The analysis determined that acupuncture can improve short and long-term physical function and mobility and provide up to 13 weeks of pain relief in individuals with chronic knee pain caused by osteoarthritis.

Rheumatoid Arthritis

• Rheumatoid arthritis is a chronic disease that affects joints, including the knee joint, causing pain and stiffness.
• Acupuncture is beneficial in treating rheumatoid arthritis/RA.
• A review found that acupuncture alone and in combination with other treatment modalities benefits individuals with RA. (Pei-Chi, Chou Heng-Yi Chu 2018)
• Acupuncture is believed to have anti-inflammatory and antioxidant effects to help regulate immune system function.

Chronic Knee Pain

• Various conditions and injuries can cause chronic knee pain, making mobility difficult.
• Individuals with joint pain often turn to complementary therapies for pain relief management, with acupuncture being one of the popular modalities. (Michael Frass et al., 2012)
• A study showed modest improvements in pain relief at 12 weeks. (Rana S. Hinman et al., 2014)
• Acupuncture resulted in modest improvements in mobility and function at 12 weeks.

Safety

• Acupuncture is considered safe when administered by a trained, licensed professional.
• Few complications have been reported from the use of acupuncture. (National Center for Complementary and Integrative Health. 2022)

Side Effects

• Side effects can include soreness, bruising, or bleeding at the site of needle insertion and dizziness.
• Less common side effects include fainting, increased pain, and nausea. (Harvard Medical School. 2023)
• Working with a licensed, professional acupuncture practitioner can reduce the risk of unwanted side effects and complications.

Types

Other acupuncture options that may be offered include:

Electroacupuncture

• A modified form of acupuncture where a mild electrical current passes through the needles, providing additional stimulation to the acupoints.
• In one research study, individuals with knee osteoarthritis reported significant improvements in their pain, stiffness, and physical function after electroacupuncture treatment. (Ziyong Ju et al., 2015)

Auricular

• Auricular or ear acupuncture works on acupoints in the ear corresponding to the body’s different parts.
• A research review analyzed several studies on auricular acupuncture for pain relief and found that it can provide relief within 48 hours of pain onset. (M. Murakami et al., 2017)

Battlefield Acupuncture

• The military and veteran healthcare facilities use a unique form of auricular acupuncture for pain management.
• Studies show that it is effective at providing immediate pain relief, but more research is necessary to determine long-term pain relief effectiveness. (Anna Denee Montgomery, Ronovan Ottenbacher 2020)

Before trying acupuncture, consult a healthcare professional for guidance, as it may be integrated with other therapies and lifestyle adjustments.
