But they do suggest that the popular treatment can be an effective adjunctive, or complementary, therapy for people with osteoarthritic knees.

Researchers at the University of Maryland Center for Integrative Medicine conducted the 570-person study — the largest and best-designed trial of acupuncture to date. Women and men age 50 or over with osteoarthritis of the knee were assigned to one of three groups: true acupuncture, "sham" acupuncture, or arthritis education.
