Observation Of Clinical Efficacy Of Ultrasound-Guided Water Needle Knife Treatment For Adhesive Capsulitis

ObjectiveThis study aims to evaluate the clinical efficacy of ultrasound-guided water needle knife therapy for treating adhesive capsulitis and provide clinical evidence to support its use.MethodsA total of 66 patients with adhesive capsulitis(adhesive phase)were randomly divided into a control group and an observation group,with 33 patients in each group.Both groups received basic treatment(acupuncture and functional exercise).The control group was treated with small needle knife,which performed sharp loosening through the needle blade;the observation group was treated with water needle knife,which performed water separation loosening by injecting physiological saline through the hollow needle body of the water needle knife.Both groups underwent loosening operations under ultrasound guidance,targeting the subcoracoid bursa,the internodular bursa,the subacromial bursa,the subdeltoid bursa,and the posterior joint capsule.Both groups received weekly treatment once a week for 3 weeks.Before the first treatment and the first day after the last treatment,the thickness of the inferior capsule was measured by musculoskeletal ultrasound,and VAS score,CMS score,and ROM of shoulder flexion,abduction,external rotation,and internal rotation were evaluated.Results(1)The thickness of inferior capsule:(1)within-group comparison:the thickness of the affected side in both groups decreased after treatment,and the differences were statistically significant(P< 0.05);(2)between-group comparison:the thickness of the affected side in the observation group was lower than that in the control group after treatment,and the difference was statistically significant(P<0.05).(2)VAS score:(1)within-group comparison:the VAS score in both groups decreased after treatment,and the differences were statistically significant(P < 0.05);(2)between-group comparison:the VAS score in the observation group was lower than that in the control group after treatment,and the difference was statistically significant(P<0.05).(3)CMS score:(1)within-group comparison:the CMS score in both groups increased after treatment,and the differences were statistically significant(P < 0.05);(2)between-group comparison:the CMS score in the observation group was higher than that in the control group after treatment,and the difference was statistically significant(P<0.05).(4)ROM:(1)within-group comparison:the ROM of shoulder flexion,abduction,external rotation,and internal rotation increased in both groups after treatment,and the differences were statistically significant(P<0.05);(2)between-group comparison:the ROM of shoulder flexion,abduction,external rotation,and internal rotation in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).(5)Efficacy evaluation:the total effective rate was 83.87% in the control group and 96.88%in the observation group after treatment,and the difference between the groups was statistically significant(P<0.05).Conclusions(1)Ultrasound-guided water needle knife therapy can effectively reduce the degree of IC thickness in patients with adhesive capsulitis,with better efficacy than ultrasound-guided small needle knife therapy.(2)Ultrasound-guided water needle knife therapy can effectively alleviate pain,improve shoulder joint function,and increase ROM in patients with adhesive capsulitis,with better efficacy than ultrasound-guided small needle knife therapy.
