BackgroundThis systematic review aimed to evaluate the effectiveness and safety of ultrasound-guided acupotomy (UGAT) therapy in the treatment of patients with knee osteoarthritis (KOA).MethodsWe conducted online researches in the databases including PubMed, the Cochrane Library, EMBASE, China national knowledge infrastructure, China biomedical literature database, and Wan Fang data. All data were collected until January 1, 2022. Relevant randomized controlled trials on the effectiveness of UGAT for the treatment of KOA were included. Meta-analyses were carried out by RevMan 5.3 software. Evidence quality was evaluated by the grading of recommendations, assessment development, and evaluation.ResultsEight studies including 543 participants were analyzed in this study. The pooled analysis indicated that UGAT was significantly more efficient than the control group in decreasing the visual analogue scale score (mean difference = -0.81, 95% confidence interval (CI) = [-1.15, -0.47], P < .00001, 8 studies), improving knee function on the Lysholm knee score (mean difference = 8.26, 95% CI = [1.56, 14.97], P = .02, 2 studies), and increasing clinical effective rate (relative risk = 1.14, 95% CI = [1.06, 1.23], P = .0005, 6 studies). For adverse events, UGAT was also associated with lower incidence of adverse event (odds ratio = 0.27, 95% CI = [0.12, 0.63], P = .002, 4 studies) compared to traditional acupotomy.ConclusionCurrent evidence suggested that UGAT therapy was effective and safe in the clinical treatments of KOA, thus could be suggested in the clinical managements of KOA. However, considering the unsatisfactory quality of the available trials, more large-scale, and better quality randomized controlled trials were recommend in future.Copyright © 2023 the Author(s).
