膝关节骨关节炎(knee osteoarthritis, KOA)因其显著且持续的疼痛和功能障碍,已成为全球主要的致残因素之一。其疼痛的核心机制是机械损伤与关节退变触发“滑膜炎症-血管增生-神经支配异常-敏化”的恶性循环。传统保守治疗(如非甾体抗炎药、关节内注射)疗效有限,而全膝关节置换术(total knee arthroplasty, TKA)存在高风险和恢复期长等问题。膝动脉栓塞术(genicular artery embolization, GAE)作为一种新兴微创介入疗法,通过靶向栓塞膝关节异常新生血管,阻断滑膜炎症介导的神经血管耦联通路,从而达到缓解疼痛的目的。本文综述了KOA疼痛的病理生理机制、GAE的临床疗效、安全性及当前关键争议的最新循证依据,评估其在KOA阶梯治疗体系中的潜在价值与定位,并探讨未来研究方向。

Knee Osteoarthritis (KOA), characterized by significant and persistent pain and functional impairment, has emerged as a major global cause of disability. The core mechanism underlying its pain involves mechanical injury and joint degeneration triggering a vicious cycle of "synovitis-vascular proliferation-aberrant innervation-sensitization". Conventional conservative treatments (such as NSAIDs and intra-articular injections) offer limited efficacy, while Total Knee Arthroplasty (TKA) is constrained by its high-risk profile and prolonged recovery period. Genicular Artery Embolization (GAE), an emerging minimally invasive interventional therapy, aims to alleviate pain by selectively embolizing abnormal neovessels within the knee joint. This targeted approach disrupts the neurovascular coupling pathway mediated by synovial inflammation. This article systematically reviews the current evidence-based basis regarding the pathophysiology of KOA pain, GAE's clinical efficacy, safety profile, and key ongoing deliberations. It evaluates the potential value and positioning of GAE within the stepwise treatment framework for KOA and explores future research directions.
