Abstract

AimsTo determine the effectiveness of acupuncture as a therapy complementary to the pharmacological treatment of osteoarthritis of the knee.MethodsRandomised, single blind, placebo controlled trial. Patients with osteoarthritis of the knee were randomly assigned to either 12 sessions of true acupuncture or 12 sessions of placebo acupuncture (Streitberger needle), these sessions taking place once a week. A baseline measurement was carried out, followed by further observations at 4, 8, 12 and 16 weeks. The clinical variables were the WOMAC (Western Ontario and McMaster Universities Osteoarthritis) index, knee pain measured by a visual analogue scale (pain VAS), the weekly consumption of diclofenac and the Profile of the Quality of Life of the Chronically Ill (PQLC). The two groups were compared for each of the clinical variables per protocol and by intention to treat. A multiple linear regression model for the dependent variables was constructed.ResultsNinety seven outpatients were selected, with 88 remaining for the per protocol analysis; the analysis of homogeneity concluded that the lost subjects were not significantly different from those that completed the study.
