    Abstract:
    BACKGROUND: This study aims to determine whether 3 sessions per week of acupuncture treatment is superior to 1 session per week of acupuncture treatment for symptomatic outcomes in knee osteoarthritis. METHODS/DESIGN: This is a two parallel-group, assessor-blinded, randomized controlled trial. Sixty patients with knee osteoarthritis (Kellgren-Lawrence grade II or III) will be recruited and randomly allocated to receive 24 or 8 sessions (group M or group L) of acupuncture treatment in a 1:1 ratio. Patients in group M will receive 3 sessions per week of acupuncture for 8 weeks. Patients in group L will receive acupuncture once per week for 8 weeks. The primary outcome is the response rate-the percentage of patients achieving a decrease ≥ 2 points on a numerical rating pain scale and a decrease ≥ 6 points in the Western Ontario and McMaster Universities Osteoarthritis Index function score at 8 weeks compared with baseline. Secondary outcomes include pain, function, overall effect, quality of life, and treatment credibility and expectancy. DISCUSSION: Three sessions per week of acupuncture treatment may be superior to 1 session per week of acupuncture treatment for symptomatic outcomes in knee osteoarthritis. Results of the study will be of great importance for the guidelines of clinical therapy. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03359603 . Registered on 1 December 2017.
