Acupuncture for hip osteoarthritis.

Area of Science:

• Evidence-based medicine
• Complementary and alternative medicine
• Rheumatology

Background:

• Hip osteoarthritis (OA) significantly impacts pain and function, with limited evaluated treatment options.
• Acupuncture, a traditional Chinese therapy, involves inserting fine needles at specific body points.
• Few treatments for hip OA have undergone rigorous safety and effectiveness evaluation.

Purpose of the Study:

• To evaluate the safety and effectiveness of acupuncture for hip osteoarthritis (OA).
• To assess benefits and harms of acupuncture in patients diagnosed with hip OA.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) sourced from Cochrane CENTRAL, MEDLINE, and Embase up to March 2018.
• Included RCTs compared acupuncture to sham acupuncture, active treatments, or no treatment, or as an adjunct therapy.
• Primary outcomes focused on pain and function at short-term follow-up (<3 months) and adverse events.

Main Results:

• Two sham-controlled RCTs (120 participants) indicated moderate-quality evidence of little to no effect of acupuncture on pain and function.
• Four unblinded RCTs suggested low-quality evidence of benefits for pain and function when acupuncture was added to routine primary care.
• Minor side effects like bruising or bleeding at needle sites were reported; no serious adverse events were attributed to acupuncture.

Conclusions:

• Acupuncture likely provides minimal to no pain relief or functional improvement compared to sham acupuncture for hip OA.
• While one trial suggested benefits when added to primary care, these may be influenced by participant expectations.
• The overall quality of evidence for comparative effectiveness was low to very low, necessitating cautious interpretation.
