Acupuncture is ‘not profitable for knee pain’

According to a new investigate published in JAMA, pain-killer – possibly in a normal needle or complicated laser form – does not yield poignant pain service from ongoing knee pain or alleviation in knee function.

The justification ancillary pain-killer for relieving knee pain is mixed.

Traditional Chinese pain-killer involves inserting needles during specific points in a body, in a faith that doing so helps channel a “life force” famous as Qi.

In complicated Western acupuncture, it is believed that a needles kindle nerves underneath a skin, producing pain-relieving endorphins. The diagnosis is now also offering in a non-penetrative form, where low-intensity lasers are practical to pain-killer points.

In systematic trials, a outcomes of participants receiving pain-killer are compared with a outcomes of participants receiving “sham acupuncture,” that customarily involves a focus of retractable, non-penetrating needles to points of a physique not used in customary acupuncture.


Despite a augmenting recognition as an choice therapy, trials have shown that a justification ancillary pain-killer for relieving knee pain is mixed.

A 2006 investigate of 1,007 patients with knee pain found that nonetheless 53% of participants receiving pain-killer reported reduction pain and softened duty during 26 weeks, so did 51% of a participants receiving sham acupuncture. Also, 29.1% of patients who perceived no pain-killer in that investigate reported reduction pain and softened function.

In 2010, a investigate published in Arthritis Care Research likewise found that needle pain-killer and sham pain-killer were about a same in terms of outcomes for patients with osteoarthritis of a knee.

In a new study, researchers from a University of Melbourne in Australia incidentally reserved 282 ongoing knee pain patients aged 50 years and comparison to possibly accept needle acupuncture, laser acupuncture, sham laser pain-killer or no acupuncture. In sham laser acupuncture, a laser is inactive, and conjunction a participants nor a acupuncturists in a hearing knew when a laser pain-killer was sham or active.

‘No poignant difference’ between pain-killer and sham pain-killer outcomes

After 12 weeks of treatment, a needle pain-killer organisation and sham pain-killer groups reported some softened earthy duty compared with a organisation who perceived no acupuncture. Participants receiving possibly needle or laser pain-killer also reported medium improvements in pain control. However, conjunction pain nor earthy duty were softened after 1 year.


In terms of knee pain and earthy function, a researchers found no poignant differences between pain-killer and sham laser acupuncture.

The researchers also found no poignant differences in delegate outcomes – such as peculiarity of life – between participants who had active or dead acupuncture. The organisation did find that pain on walking softened in a needle pain-killer organisation during 12 weeks, though this was not confirmed during a 1-year follow-up.

The authors consider that a series of immaterial factors might change outcomes, including:

  • Treatment setting
  • Patient expectations and attitudes (such as optimism)
  • Acupuncturist’s certainty in treatment
  • Patient and acupuncturist interaction.

They write:

“In a study, advantages of pain-killer were exclusively attributed to immaterial effects, given a miss of poignant differences between active pain-killer and sham treatment. Continuous biased measures, such as pain and self-reported earthy function, as used in a study, are quite theme to remedy responses.

In patients comparison than 50 years with assuage or serious ongoing knee pain, conjunction laser nor needle pain-killer conferred advantage over sham for pain or function. Our commentary do not support pain-killer for these patients.”
