Electroacupuncture (EA), a modality combining traditional acupuncture with electrical stimulation, has gained attention as a non-pharmacological intervention for KOA. Growing evidence suggests that EA not only reduces pain and enhances joint mobility but also modulates diverse biological processes-such as neuroendocrine signaling, inflammatory cascades, cartilage metabolism, and local hemodynamics. Mechanistically, EA acts through multi-target mechanisms, including suppression of pro-inflammatory mediators, promotion of anti-inflammatory and chondroprotective factors, and regulation of critical signaling pathways such as NF-κB, MAPK, and Wnt/β-catenin. Additionally, EA engages central and peripheral neuromodulatory systems involving opioid, serotonergic, and cannabinoid receptors, underpinning its analgesic properties. Despite encouraging outcomes, current support derives predominantly from small-scale clinical trials with short follow-up periods, underscoring the necessity for large-scale, randomized controlled studies with rigorous designs to establish standardized protocols and validate long-term benefits.
