Acupuncture for treatment of knee osteoarthritis: A clinical practice guideline.

Compared with no treatment, acupuncture is suggested to reduce pain, stiffness, and disfunction in KOA patients, ultimately improving the patient's health status. Acupuncture can be used as an alternative therapy when usual care is ineffective or there are adverse reactions so that patients can no longer continue the treatment. Manual acupuncture or electroacupuncture is suggested for 4-8 weeks to improve the health status of KOA. The patient's values and preferences should be considered when selecting acupuncture for KOA treatment.
