Abstract：
UNASSIGNED: Pulsed radiofrequency (PRF) of the saphenous nerve (SN) has shown effective pain relief in knee pain because of knee osteoarthritis (KOA). The adductor canal (AC) contains other sensory nerves innervating the medial part of the knee joint apart from SN. We compared the PRF of SN within and outside the AC for their quality and duration of pain relief in knee osteoarthritis of the medial compartment (KOA-MC).
UNASSIGNED: We conducted a randomized prospective study in 60 patients with anteromedial knee pain because of KOA-MC. Patients in group A received PRF-SN, and those in group B received PRF-AC. The primary objectives were comparison of pain by Visual Analog Scale (VAS) scores and changes in quality of daily living by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and OXFORD knee scores. The secondary objectives were comparison of analgesic requirements using Medicine Quantification Scale (MQS) scores and block-related complications. Intra-group comparison was performed by analysis of variance. Inter-group normally distributed data were assessed by Student\'s t-test, non-normally distributed and ordinal data were assessed by Mann-Whitney U-test, and categorical data were assessed by Chi-square test. A P value of <0.05 was considered significant.
UNASSIGNED: VAS scores were significantly lower in Gr-B at 12 weeks. The WOMAC scores and OXFORD scores at 4, 8, 12, and 24 weeks were significantly lower in Gr-B compared to Gr-A.
UNASSIGNED: The PRF-AC provides better pain relief and functional outcome than PRF-SN; however, duration of pain relief was not significantly different.

摘要：
■由于膝骨关节炎（KOA），隐神经（SN）的脉冲射频（PRF）在膝关节疼痛中显示出有效的疼痛缓解。内收肌管（AC）包含除SN外的其他感觉神经支配膝关节的内侧部分。我们比较了AC内外SN的PRF，以了解它们在内侧室膝骨关节炎（KOA-MC）中疼痛缓解的质量和持续时间。
■我们在60例因KOA-MC引起的膝前内侧疼痛患者中进行了一项随机前瞻性研究。A组患者接受PRF-SN,B组接受PRF-AC治疗。主要目标是通过视觉模拟量表（VAS）评分比较疼痛，并通过西安大略省和麦克马斯特大学骨关节炎指数（WOMAC）和OXFORD膝关节评分比较日常生活质量的变化。次要目标是使用医学量化量表（MQS）评分和与阻滞相关的并发症比较镇痛需求。组间比较采用方差分析。组间正态分布数据采用学生t检验进行评估，非正态分布和序数数据采用Mann-WhitneyU检验进行评估，分类数据采用卡方检验。<0.05的P值被认为是显著的。
■12周时Gr-B的VAS评分显著降低。与Gr-A相比，Gr-B在第4、8、12和24周的WOMAC得分和OXFORD得分显着降低。
■PRF-AC比PRF-SN提供更好的疼痛缓解和功能效果；然而，疼痛缓解的持续时间没有显著差异.
