Context • Knee osteoarthritis is a common form of joint disease found in humans and one of the leading causes of disability globally. Knee osteoarthritis (KOA) is responsible for a higher number of disabilities than any other medical condition affecting activities of daily living (ADL). To date no definitive, conventional medical protocol is available to deal with KOA. Objectives • The study intended to clinically investigate whether the benefits of acupuncture in the treatment of KOA) could be augmented by the addition of Chinese herbal fumigation steam therapy (CHFST) to the treatment protocol and to what degree it had benefits. Design • The research team designed a three-armed, randomized, controlled trial. The sample size was determined by analysis of power; for a sample size of 42, the power was 83.5%; the effect size was 0.5; and the α was 0.05. Setting • The setting was the traumatology department in the Chinese Medicine Branch of Taipei City Joint Hospital in Kun Ming, Taiwan. Participants • Participants were 45 males and females between the ages of 35 and 75, who were patients in the traumatology department and who were suffering from bilateral knee osteoarthritis. Three participants were lost to follow-up. Interventions • Participants were randomly assigned to one of three groups, each with 15 participants; (1) the control group, who received acupuncture only; (2) the normal CHFST group, an intervention group who received acupuncture plus a normal dose of CHFST; and (3) the one-sixteenth CHFST group, an intervention group who received acupuncture plus one-sixteenth of a normal dose of CHFST. Participants underwent biweekly treatments for four consecutive weeks. Outcomes Measures • The primary outcome measures included a visual analog scale (VAS) to assess variations in pain intensity and a goniometer measure for range of motion (ROM). Results • The addition of CHFST to acupuncture in the treatment of KOA significantly reduced pain (P = .0017) for the normal CHFST group compared to the control group and the one-sixteenth CHFST group. Chinese medical interventions overall for all groups showed a decrease in pain and increases in ROM, and health related quality of life (HrQoL). Conclusions • CHFST, in conjunction with acupuncture, showed promise in the treatment of KOA in reducing pain, increasing ROM, and improving quality of life (QoL).
