To evaluate the clinical and functional outcomes of the pharmacological block of the genicular nerves as a modality in the therapeutic arsenal for knee osteoarthritis, since it is simple, safe, and minimally invasive. The pharmacological block of the genicular nerves was performed in 20 patients with grades 3 and 4 knee osteoarthritis per the Kellgren-Lawrence classification. We assessed their clinical and functional outcomes one, three, and six months after the procedure. Of the 20 patients undergoing the procedure, 16 (80%) presented an excellent response in the first month of outpatient follow-up, since their pain level went from 8/9 to 2/3; 2 subjects presented a partial response, and 2 others did not respond to the treatment. The pharmacological block of the genicular nerves is efficient in reducing pain and improving the performance of daily activities by the patients, especially up to three months after the procedure.
为评估膝神经药物阻滞作为膝骨关节炎治疗手段的临床和功能结局，因其操作简单、安全且微创。
根据凯尔格伦-劳伦斯分类法，对20例3级和4级膝骨关节炎患者进行了膝神经药物阻滞。我们在术后1个月、3个月和6个月评估了他们的临床和功能结局。
在接受该手术的20例患者中，16例（80%）在门诊随访的第一个月表现出极佳的反应，因为他们的疼痛程度从8/9降至2/3；2例患者有部分反应，另外2例对治疗无反应。
膝神经药物阻滞在减轻疼痛和改善患者日常活动能力方面是有效的，尤其是在术后三个月内。
