A healthy 50-year-old woman comes to her primary care physician’s office. She has early osteoarthritis in her knees, hips, and feet. She has been taking ibuprofen with some relief, but is reluctant to be on long-term medication. She asks if acupuncture could be an effective treatment for her arthritis. Her primary care physician asks you to research this and let him know what you find before the patient’s next appointment.
