Objective:To explore the clinical efficacy of ultrasound-guided acupotomy therapy in treatment of knee osteoarthritis(KOA).Methods:50 patients with KOA were randomly assigned into the observation group and the control group,with 25 patients in each group.The observation group received ultrasound-guided acupotomy therapy,once a week for 5 weeks;whereas the control group received traditional acupotomy therapy,once a week for 5 weeks.Scores of Visual Analog Scale(VAS),Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC),Lysholm knee assessment and Self-Rating Anxiety Scale(SAS)were compared between the two groups at the second week of treatment,at the end of treatment,and at 7-week follow-up after the treatment.Results:At the second week of treatment,the observation group showed significantly better scores compared to the control group(P＜0.01).There were no significant differences in scores between the observation group and the control group at the end of treatment(P＞0.05).However,at the 7-week follow-up visit,the observation group demonstrated superior scores compared to the control group(P＜0.01).Conclusion:Ultrasound-guided acupotomy therapy is more effective than traditional acupotomy therapy in rapidly relieving pain and anxiety symptoms,improving joint function,and achieving significant long-term efficacy for patients with KOA.
