Abstract: 【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.
