研究目的:

本研究拟开展一项随机双盲对照试验,以全膝关节置换术后患有慢性疼痛超过3月的患者为研究对象,评估超声引导下行收肌管阻滞(ACB)+膝神经阻滞(PNB)与收肌管阻滞(ACB)+假手术在膝关节置换术后慢性疼痛患者疼痛控制中的有效性和持续时间,旨在为临床实践提供最佳指导依据。  

Objectives of Study:

This study intends to conduct a randomized double-blind controlled trial, targeting patients who have suffered from chronic pain for more than 3 months after total knee arthroplasty. The study aims to evaluate the efficacy and duration of ultrasound-guided adductor canal block (ACB) + knee nerve block (PNB) versus adductor canal block (ACB) + sham surgery in pain control for patients with chronic pain after knee arthroplasty, with the aim of providing the best guidance for clinical practice.
