Abstract
BACKGROUND:Symptomatic knee osteoarthritis (KOA) is common in China. Pharmacological therapy is not the first recommendation because of its safety issues. Nonpharmacological therapy, such as lifestyle adjustments, weight loss, muscle strengthening, and aerobic exercise programs, is strongly recommended for KOA. However, these approaches may fail due to poor patient compliance. There is a lack of high-quality randomized controlled trials of acupotomy, an effective treatment for KOA. This study was designed to investigate the efficacy of acupotomy in patients with KOA. METHODS: A total of 136 patients will be enrolled at the First Affiliated Hospital of Guangzhou University of Chinese Medicine and assigned to theacupotomy group or sham acupotomy group according to the block randomization scheme. Patients in the acupotomy group will receive 2 sessions of acupotomy for 2 weeks (once a week). Patients in the sham group will receive 2 sessions of sham stimulation for 2 weeks (once a week). All patients will use indomethacin cream externally. The primary outcome will be the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the secondary outcomes will be the visual analog scale (VAS) score, plantar pressure distribution test result, X-ray examination findings, musculoskeletal ultrasound findings, maximum knee circumference, joint mobility, and quality of life. Measurements will be taken at baseline, 1 week after the end of treatment, and at the 3- and 6-month follow-ups. DISCUSSION: To the best of our knowledge, this will be the first single-blind, sham-controlled study of acupotomy. The outcome assessors will also be blinded. The aim of this work is to demonstrate the efficacy of acupotomy in treating KOA. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2000033047 . Registered on 18 May 2020.
