We found that only a quarter of patients had weight-bearing x-rays before the MRI. We found that half of the MRIs obtained prior to referral to an orthopaedic surgeon did not contribute to the patient’s treatment.

School of Health Sciences, Faculty of Medicine, Dentistry and Health Sciences, University of Melbourne, Melbourne, Australia

Medical Research: What are the main findings of the study?

Dr. Metcalf: This study investigated whether acupuncture is an effective treatment for people aged more than 50 years with chronic knee pain. Participants in our study were randomly assigned to one of four groups; needle acupuncture, laser acupuncture, sham laser acupuncture or no treatment. The people in the treatment groups received acupuncture treatment from a family physician for 12 weeks. Participants were assessed after treatment and again after one year.

There were no significant differences in knee pain or physical function between active and sham laser acupuncture at 12 weeks or at one year. Both needle and laser acupuncture resulted in modest improvements in pain compared with no treatment at 12 weeks that were not maintained at one year. Needle acupuncture improved physical function at 12 weeks compared with no treatment but was not different from sham acupuncture and was not maintained at one year.
