To the Editor Among the findings in the study by Dr Hinman and colleagues1 was that at 12 weeks, needle and laser acupuncture treatment reduced pain and needle acupuncture improved functional scores compared with control in patients with knee pain persisting for longer than 3 months. One year after needle acupuncture, both outcomes (pain intensity and physical function scores) were still improved by approximately 25%, but the differences were not statistically significant. The authors concluded that their findings did not support acupuncture in patients older than 50 years with moderate or severe chronic knee pain.
