Abstract

Objective: Knee genicular nerve blocks have been a topic of discussion among various types of treatment for knee osteoarthritis. This study aims to evaluate the pain and function of patients diagnosed with knee osteoarthritis after undergoing ultrasound-guided genicular nerve blockade using pharmacological agents.

Methods: The study included 36 patients diagnosed with knee osteoarthritis, comprising 17 bilateral cases, totaling 53 knees undergoing UGNB using a mixture of triamcinolone, ropivacaine, and lidocaine under ultrasound guidance. Epidemiological data, pain outcomes measured by the Visual Analog Scale (VAS), and function assessed using the Western Ontario and McMaster Universities (WOMAC) score were evaluated before and after 12 weeks of the procedure.

Results: The mean age was 75.5 years (standard deviation of 9.4 years), with a predominance of females and right-sided involvement. There was a mean reduction of 3.0 points in VAS (p < 0.001) and 15.4 points in WOMAC (p < 0.001). Two cases reported only minor and transient complications related to the procedure (skin anesthesia and edema).

Conclusion: Ultrasound-guided genicular nerve blockade using pharmacological agents demonstrated pain reduction and improved function with a low complication rate after 12 weeks in patients with knee gonarthrosis. Level of Evidence IV, Case Series.

超声引导下膝神经阻滞治疗膝骨关节炎：病例系列。

目的：膝关节膝神经阻滞一直是膝关节骨性关节炎各种治疗方法中的一个讨论话题。本研究旨在评估膝关节骨性关节炎患者在接受超声引导下膝关节神经阻滞术后的疼痛和功能：研究纳入了36例确诊为膝关节骨性关节炎的患者，包括17例双侧病例，共计53个膝关节，在超声引导下使用曲安奈德、罗哌卡因和利多卡因的混合物进行膝关节神经阻滞。对手术前后12周的流行病学数据、视觉模拟量表（VAS）测量的疼痛结果以及西安大略和麦克马斯特大学（WOMAC）评分评估的功能进行了评估：患者平均年龄为 75.5 岁（标准差为 9.4 岁），女性居多，右侧受累。VAS 评分平均降低 3.0 分（p < 0.001），WOMAC 评分平均降低 15.4 分（p < 0.001）。两例病例仅报告了与手术相关的轻微和短暂并发症（皮肤麻醉和水肿）：结论：在超声引导下使用药物阻滞膝关节神经，12周后膝关节骨关节病患者的疼痛减轻，功能改善，并发症发生率低。证据等级 IV，病例系列。
