Corbett MS, Rice SJ, Madurasinghe V, Slack R, Fayter DA, Harden M, et al. Acupuncture and other Physical Treatments for the Relief of Pain Due to Osteoarthritis of the Knee: Network Meta-analysis. Osteoarthritis and Cartilage / OARS, Osteoarthritis Research Society. 2013;21(9):1290-8.
Summary: Out of 156 eligible studies, 114 trials (involving 9,709 patients) provided data suitable for analysis. End of treatment results showed that eight interventions: interferential therapy, acupuncture, TENS, pulsed electrical stimulation, balneotherapy, aerobic exercise, sham acupuncture and muscle strengthening exercise produced a statistically significant reduction in pain compared with standard care. Based on a summary of the current available research, the meta-analysis results indicate that acupuncture can be considered one of the more effective physical treatments for alleviated osteoarthritis knee pain in the short term.
