Clinical study of ultrasound-guided pulse radiofrequency treatment of the saphenous nerve for knee osteoarthritis
Objective To study the efficacy and safety of ultrasound-guided pulse radiofrequency(PRF)treatment of the saphenous nerve for knee osteoarthritis(KOA).Methods A total of 289 KOA patients were followed up from March 2021 to October 2023 and divided into PRF group(group A,n=142)and conservative treatment group(group B,n=147)according to different treatment methods.Pain degree(VAS),knee function(OKS),and sleep quality(AIS)of the two groups were recorded before treatment and at 1 week,1 month,3 months and 6 months after treatment;the occurrence of complications was recorded for comparison between the two groups.Results After treatment,VAS,OKS and AIS scores in both groups decreased compared with those before treatment(P＜0.001).In addition,the scores of group A showed a gradual downward trend 6 months after surgery,while the scores of group B showed an overall upward trend 6 months after surgery.The scores of VAS and OKS were significantly lower in group A than in group B from 1 week to 6 months after surgery(P＜0.001).The AIS score of group A was much lower than that of group B from 1 month to 6 months after surgery(P＜0.001).There was no significant difference in the incidence of complications between the two groups(P=0.236).Conclusion Ultrasound-guided PRF treatment of the saphenous nerve is better than conservative treatment because it can better reduce pain and improve knee joint mobility and sleep in patients with KOA.
