Complementary and Alternative Medicine Use for Knee Osteoarthritis by Older Adults in Rural Settings in Southern Taiwan

This study examined complementary and alternative medicine (CAM) use among 80 older adults with knee osteoarthritis (OA) in rural southern Taiwan. Conducted from January 2023 to March 2024, the survey revealed that 83.7% used CAM: primarily acupuncture (50.7%), exercise (26.9%), and calcium supplements (26.9%). CAM use was higher among women (86.6%) and those not regularly taking conventional medication (P = .034). Only 4.5% of knee OA patients did not inform their health care providers. The main reason for CAM use was perceived fewer side-effects. Findings highlight the need for health professionals to understand CAM practices to ensure safe, informed, and comprehensive care for rural older adults.
